Canada detects its first presumptive human H5 bird flu case

OTTAWA, Ontario — Canada has detected its first presumptive case of H5 bird flu in a person, a teenager in the western province of British Columbia, health officials said Saturday.

The teenager likely caught the virus from a bird or animal and was receiving care at a children’s hospital, the province said in a statement.

The province said it was investigating the source of exposure and identifying the teenager’s contacts. The risk to the public remains low, Canada’s Health Minister Mark Holland said in posting on X.

“This is a rare event,” British Columbia Health Officer Bonnie Henry said in a statement. “We are conducting a thorough investigation to fully understand the source of exposure here in B.C.”

H5 bird flu is widespread in wild birds worldwide and is causing outbreaks in poultry and U.S. dairy cows, with several recent human cases in U.S. dairy and poultry workers.

There has been no evidence of person-to-person spread so far. But if that were to happen, a pandemic could unfold, scientists have said.

Earlier in November, the U.S. Centers for Disease Control and Prevention asked for farm workers who have been exposed to animals with bird flu to be tested for the virus even if they do not have symptoms.

Bird flu has infected nearly 450 dairy farms in 15 U.S. states since March, and the CDC has identified 46 human cases of bird flu since April.

In Canada, British Columbia has identified at least 22 infected poultry farms since October, and numerous wild birds tested positive, according to the province.

Canada has had no cases reported in dairy cattle and no evidence of bird flu in samples of milk.

Experts release new guidelines for preventing strokes

Most strokes could be prevented, according to new guidelines aimed at helping people and their doctors do just that. 

Stroke was the fourth-leading cause of death in the U.S. in 2023, according to the Centers for Disease Control and Prevention, and more than half a million Americans have a stroke every year. But up to 80% of strokes may be preventable with better nutrition, exercise and identification of risk factors. 

The first new guidelines on stroke prevention in 10 years from the American Stroke Association, a division of the American Heart Association, include recommendations for people and doctors that reflect a better understanding of who gets strokes and why, along with new drugs that can help reduce risk. 

The good news is that the best way to reduce your risk for stroke is also the best way to reduce your risk for a whole host of health problems — eat a healthy diet, move your body and don’t smoke. The bad news is that it’s not always so easy to sustain. 

Dr. Sean Duke, a stroke doctor at the University of Mississippi Medical Center, blames the forces in society that keep people sedentary and eating poorly, like cell phones and cheap, unhealthy food. “Our world is stacked against us,” he said. 

Here’s what to know about stroke and the new guidelines: 

What is a stroke? 

A stroke happens when blood flow to part of the brain is blocked or if a blood vessel in the brain bursts. That deprives the brain of oxygen which can cause brain damage that can lead to difficulty thinking, talking and walking, or even death. 

How eating healthy can reduce your risk for stroke 

Eating healthy can help control several factors that increase your risk for stroke, including high cholesterol, high blood sugar, and obesity, according to the heart association. 

The group recommends foods in the so-called Mediterranean diet such as fruits, vegetables, whole grains and olive oil, which can help keep cholesterol levels down. It suggests limiting red meat and other sources of saturated fat. Instead, get your protein from beans, nuts, poultry, fish and seafood. 

Limit highly processed foods and foods and drinks with a lot of added sugar. This can also reduce your calorie intake, which helps keep weight in check. 

Moving your body can help prevent strokes 

Getting up and walking around for at least 10 minutes a day can “drastically” reduce your risk, said Dr. Cheryl Bushnell, a neurologist at Wake Forest University School of Medicine who was part of the group that came up with the new guidelines. Among the many benefits: Regular exercise can help reduce blood pressure, a major risk factor for stroke. 

Of course, more is better: The heart association recommends at least 150 minutes of moderate aerobic or 75 minutes of vigorous activity — or some combination — per week. How you do it doesn’t matter so much, experts said: Go to the gym, take a walk or run in your neighborhood or use treadmills or stepper machines at home. 

New tools to reduce obesity, a risk factor for stroke 

Diet and exercise can help control weight, another important risk factor for strokes. But a new class of drugs that can drastically reduce weight have been approved by regulators, providing new tools to reduce stroke risk since guidelines were last updated. 

The guidelines now recommend that doctors consider prescribing these drugs, including those sold under the brand names Ozempic, Wegovy, Mounjaro and Zepbound, to people with obesity or diabetes. 

But while those drugs can help, people still need to eat well and get exercise, cautions Dr. Fadi Nahab, a stroke expert at Emory University Hospital. 

Guidelines help identify people who might be at higher risk 

The new guidelines for the first time recommend doctors screen patients for other factors that could increase stroke risk, including sex and gender and non-medical factors such as economic stability, access to health care, discrimination and racism. For example, the risk for having a first stroke is nearly twice as high for Black adults in the U.S. as it is for white adults, according to the CDC. 

“If somebody doesn’t have insurance or they can’t get to a doctor’s office because of transportation issues or they can’t get off work to get health care … these are all things that can impact the ability to prevent stroke,” Bushnell said. 

Doctors may be able to point to resources for low-cost health care or food, and can give ideas about how to be active without breaking the bank for a gym membership. 

The guidelines also now recommend doctors should screen for conditions that could increase a woman’s risk for stroke, such as high blood pressure during pregnancy or early menopause. 

How do I know if I’m having a stroke and what do I do? 

Three of the most common stroke symptoms include face weakness, arm weakness and difficulty speaking. And time is important, because brain damage can happen quickly and damage can be limited if a stroke is treated quickly. Stroke experts have coined an acronym to help you remember: FAST. F for face, A for arm, S for speech, and T for time. If you think you or a loved one could be having a stroke, call 911 right away.

Climate, health crises must be resolved together, experts say

GENEVA — Ahead of next week’s U.N. Climate Change Conference, or COP29, in Baku, Azerbaijan, health experts warn that the climate crisis is also a health crisis and say they must be addressed in tandem to save the planet for future generations.

“Human health and planetary health are intertwined,” U.N. Secretary-General Antonio Guterres said in a statement. “Countries must take meaningful action to protect their people, boost resources, cut emissions, phase out fossil fuels and make peace with nature.”

His call for action is buttressed by Tedros Adhanom Ghebreyesus, the WHO director-general, who calls COP29 “a crucial opportunity for global leaders to integrate health considerations into strategies for adapting to and mitigating climate change.”

In preparation for the climate summit, the World Health Organization, in collaboration with more than 100 organizations and 300 experts, has developed a plan of action to protect the health of all people, “particularly the estimated 3.6 billion people who live in areas which are most susceptible to climate change.”

“This document is a collective call from the health community to make sure that everybody understands the devastating impacts that climate change is having on our health” and to know what actions must be taken to prevent the worst from happening, Dr. Maria Neira, director of the WHO’s Environment Department, told journalists at a briefing Thursday.

“We must move away from fossil fuel subsidies,” she said, noting that “implementing fair carbon pricing and, of course, mobilizing the finance that is needed for climate and health action could save millions of lives every year.”

WHO data show the many ways in which climate change threatens human lives. Between 2030 and 2050, the WHO estimates that climate change will cause 250,000 additional deaths every year “from malnutrition, malaria, diarrhea and heat stress alone.”

Without preventive action, the WHO warns, temperature and precipitation changes will spread death and illness from vector-borne diseases, which currently stand at more than 700,000 a year. It says heat-related deaths among people over age 65 have risen by 70% in two decades and are likely to rise further as the planet heats up.

“If we were to meet the Paris Agreement goals, we would save somewhere in the region of a million lives a year from reduced air pollution alone,” said Dr. Diarmid Campbell-Lendrum, WHO team lead for climate change and health.

The 2016 Paris Agreement on climate change enjoins nations to keep greenhouse gas emissions from rising 1.5 degrees Celsius above preindustrial levels. The U.N. environment agency’s annual emissions gap report, however, finds the world is headed in the wrong direction, with temperatures likely to rise to 3.1 degrees Celsius above preindustrial levels by the end of the century if preventive action is not taken.

“At the moment, the world is currently massively subsidizing fossil fuel consumption,” Campbell-Lendrum said. “The costs of fossil fuel consumption are not only felt in the atmosphere, they are felt in people’s lungs, old people’s lungs, triggering heart attacks and so on, but also young people’s lungs, impairing their development, giving them asthma, hampering their life chances.

“If we were to invest those resources more wisely, then we would have both a healthier planet and also much healthier populations,” he said, adding that financing climate action “is a really good investment, in that you get a lot more back than you put in.”

“We will be able to save almost 2 million lives a year and bring in $4 in benefits for every $1 that you invest in climate action,” he said.

His colleague, Dr. Vanessa Kerry, WHO director-general special envoy for climate change health, agreed that the world cannot afford to ignore the warnings of the impact of climate change on health.

“Whether we choose to recognize it or not, climate change is here. Its impacts are accelerating, altering our ecosystems and communities and threatening our lives.

“Poor health destabilizes economies, widens inequalities and drives political unrest,” she said. “When people cannot access essential needs for their families and lives, it leads to political and social instability. We must address health as a fundamental part of our climate response to prevent these cascading effects.”

Kerry called on leaders gathering for COP29 to urgently “fast-track a just transition and increase funding for health systems” and for frontline health workers to protect the most vulnerable.

Global warming tops milestone ahead of climate summit

London — 2024 is likely to be the hottest year ever recorded, with global warming already exceeding the threshold of 1.5°C above pre-industrial levels, according to scientists, who released the latest data ahead of the COP29 climate summit due to start Monday in Azerbaijan. 

Carlo Buontempo, the director of the European Union’s Copernicus Earth observation program, which produced the data, said it was an important moment for humankind. 

“I call it psychological because it’s something that has been agreed not only among scientists, but between scientists and policymakers and society and nations to use as a reference point. … It is a benchmark with respect to that global discussion,” he told the Associated Press on Thursday. 

Paris Agreement 

Keeping global warming to within 1.5°C of pre-industrial levels was a central pillar of the 2016 Paris Agreement, a deal signed by 196 countries, which forms the basis for the annual COP summits. Scientists say exceeding that threshold will likely have catastrophic impacts. 

“It can be the difference between a country existing, particularly small island developing states, and not. We’re also nearing a lot of Earth system tipping points,” said Ruth Townend, a senior research fellow at Britain’s Chatham House and co-author of its recent report, Azerbaijan’s climate leadership challenge. 

“Our delicate Earth systems are in a fine balance. And once we pass certain thresholds, we can trigger climate impacts that might not be reversible, moving ourselves into new types of systems.” 

Emissions gap 

As for the current trajectory, the United Nations says the world is heading toward around 3°C of warming by the end of this century. 

“We are teetering on a planetary tightrope,” U.N. Secretary-General Antonio Guterres said in a recorded message ahead of the summit. 

“Either leaders bridge the emissions gap or we plunge headlong into climate disaster, with the poorest and most vulnerable suffering the most. This report shows annual greenhouse gas emissions at an all-time high, rising 1.3% last year. They must fall 9% each year to 2030 to limit global temperature rise to 1.5°C and avoid the very worst of climate change,” Guterres said. 

COP29 

Such is the backdrop for the COP29 summit in Baku.  

Over 12 days, hundreds of world leaders and thousands of delegates will enter thorny negotiations on how to cut global greenhouse gas emissions — and, crucially, who should pay for those cuts, along with the adaptation measures necessary to mitigate against climate change caused by past emissions. 

Who pays? 

A key part of COP29 is “to establish the finance in place to help developing countries produce strong new climate plans,” explained Townend.  

“And those climate plans are meant to be delivered ahead of COP30 in Brazil next year. Without the finance domino in that line of dominoes, everything will essentially fall apart a little bit because developing countries won’t have any kind of promise of support from developed countries in order to produce those ambitious new climate plans,” Townend said. 

Fossil fuels 

Some have questioned Azerbaijan’s suitability as host of the summit. It is a major producer of oil and gas — among the fossil fuels that drive climate change.  

“Around 90% of its export revenues come from oil and gas. And it is also a climate vulnerable country — so it gets around 50 to 70% of its water from over its borders, outside its borders,” Townend said. 

“So, it really is between a rock and a hard place on climate action and transition. And as such, it has a really strong interest in getting finance in place to help developing countries such as itself to find a feasible path forward,” she told VOA. 

Trump shadow 

Looming over the summit is Donald Trump’s victory in the Tuesday U.S. presidential election. 

In his first term, Trump withdrew the United States from the Paris Agreement and could do so again once he assumes the presidency in January. He has also pledged to open vast areas of the U.S. for oil and gas drilling. 

There are also fears that Trump’s proposed import tariffs could lead to a trade war with China. The U.S. and China are the top two emitters of greenhouse gases and together account for around a third of global emissions. 

The world must adapt to such tensions, said Townend. 

“We’re unlikely to be moving towards a world that is more stable with increasing climate impact. So, we do need to learn to manage under these conditions of geopolitical instability, which will only increase going forward.” 

Extreme weather 

From the wildfires currently raging in California to the recent deadly floods in Spain’s Valencia, scientists say extreme weather events are a clear indication of the urgency of curbing global warming.  

“There is very strong evidence suggesting that many of these extreme events have become more intense because of climate change. And there is a good understanding of why,” said Buontempo of the EU Copernicus program, who added it’s vital that COP29 is a success. 

“These multilateral negotiations and discussion is the mechanism we have to find a global solution,” he added.

Global warming tops crucial milestone ahead of COP29 climate summit

The COP29 climate summit is due to get under way on Monday in Baku, Azerbaijan — a country whose economy is largely based on selling fossil fuels. Over 12 days, world leaders and thousands of delegates will try to negotiate ways to cut greenhouse gas emissions, amid warnings that efforts to limit global warming are way off track.

DNA evidence rewrites long-told stories of people in ancient Pompeii

When a volcanic eruption buried the ancient city of Pompeii, the last desperate moments of its citizens were preserved in stone for centuries.

Observers see stories in the plaster casts later made of their bodies, like a mother holding a child and two women embracing as they died.

But new DNA evidence suggests things were not as they seem — and these prevailing interpretations come from looking at the ancient world through modern eyes.

“We were able to disprove or challenge some of the previous narratives built upon how these individuals were kind of found in relation to each other,” said Alissa Mittnik of the Max Planck Institute for Evolutionary Anthropology in Germany. “It opens up different interpretations for who these people might have been.”

Mittnik and her colleagues discovered that the person thought to be a mother was actually a man unrelated to the child. And at least one of the two people locked in an embrace — long assumed to be sisters or a mother and daughter — was a man. Their research was published Thursday in the journal Current Biology.

The team, which also includes scientists from Harvard University and the University of Florence in Italy, relied on genetic material preserved for nearly two millennia. After Mount Vesuvius erupted and destroyed the Roman city in 79 A.D., bodies buried in mud and ash eventually decomposed, leaving spaces where they used to be. Casts were created from the voids in the late 1800s.

Researchers focused on 14 casts undergoing restoration, extracting DNA from the fragmented skeletal remains that mixed with them. They hoped to determine the sex, ancestry and genetic relationships between the victims.

There were several surprises in “the house of the golden bracelet,” the dwelling where the assumed mother and child were found. The adult wore an intricate piece of jewelry, for which the house was named, reinforcing the impression that the victim was a woman. Nearby were the bodies of another adult and child thought to be the rest of their nuclear family.

DNA evidence showed the four were male and not related to one another, clearly showing “the story that was long spun around these individuals” was wrong, Mittnik said.

Researchers also confirmed Pompeii citizens came from diverse backgrounds but mainly descended from eastern Mediterranean immigrants – underscoring a broad pattern of movement and cultural exchange in the Roman Empire. Pompeii is located about 241 kilometers from Rome.

The study builds upon research from 2022 when scientists sequenced the genome of a Pompeii victim for the first time and confirmed the possibility of retrieving ancient DNA from the human remains that still exist.

“They have a better overview of what’s happening in Pompeii because they analyzed different samples,” said Gabriele Scorrano of the University of Rome Tor Vergata, a co-author of that research who was not involved in the current study. “We actually had one genome, one sample, one shot.”

Though much remains to be learned, Scorrano said, such genetic brushstrokes are slowly painting a truer picture of how people lived in the distant past.

US health officials call for expanded bird flu testing for farm workers

Federal health officials on Thursday called for more testing of employees on farms with bird flu after a new study showed that some dairy workers had signs of infection, even when they didn’t report feeling sick. 

Farmworkers in close contact with infected animals should be tested and offered treatment even if they show no symptoms, said Dr. Nirav Shah, principal director of the U.S. Centers for Disease Control and Prevention. 

The new guidance comes after blood tests for 115 farmworkers in Michigan and Colorado showed that eight workers — or 7% — had antibodies that indicated previous infection with the virus known as Type A H5N1 influenza. 

“The purpose of these actions is to keep workers safe, to limit the transmission of H5 to humans and to reduce the possibility of the virus changing,” Shah told reporters. 

The CDC study provides the largest window to date into how the bird virus first detected in March in dairy cows may be spreading to people. It suggests that the virus has infected more humans than the 46 farmworkers identified in the U.S. as of Thursday. Nearly all were in contact with infected dairy cows or infected poultry. 

Outside experts said it’s notable that the study prompted the CDC to take new action. Previous recommendations called for testing and treating workers only when they had symptoms. 

“This is a significant move towards the assessment that these H5N1 viruses are a greater risk than the CDC estimated before,” said Dr. Gregory Gray, an infectious disease researcher at the University of Texas Medical Branch in Galveston. 

Every additional infection in animals or humans gives the virus the chance to change in potentially dangerous ways, said Angela Rasmussen, a virus expert at the University of Saskatchewan in Canada. 

“It shows yet again that we are not responding effectively to the H5N1 cattle outbreak in humans or animals and if we continue to let this virus spread and jump from species to species, our luck will eventually run out,” Rasmussen said in an email. 

The CDC study included 45 workers in Michigan and 70 in Colorado tested between June and August. Of the eight workers with positive blood tests, four reported no symptoms. All eight cleaned milking parlors and none used respiratory protection such as face masks. Three said they used eye protection. 

High levels of the virus have been found in the milk of infected cows, increasing the risk of exposure and infection, researchers said. 

Researchers said that efforts to monitor dairy workers for illness have been hindered by several barriers including the reluctance of farm owners and farmworkers to allow testing. 

The virus has been confirmed in at least 446 cattle herds in 15 states. Last week, the Agriculture Department said a pig at an Oregon farm was confirmed to have bird flu, the first time the virus was detected in U.S. swine.

Mpox spread slows slightly in Africa

KINSHASA, DEMOCRATIC REPUBLIC OF CONGO — The spread of mpox has slowed down slightly across Africa, but the epidemic is not over, the African Union’s health watchdog said Thursday.

Fifteen countries across Africa recorded 11,453 mpox cases in the last four weeks, compared with 12,802 in the four weeks prior, the Africa Centers for Disease Control and Prevention said during an online briefing.

But the head of the Africa CDC, Jean Kaseya, warned the epidemic was not over.

“We are still in the acute phase of the outbreak that is pushing us to double our effort to control mpox in Africa,” Kaseya said.

“Unfortunately, we are still losing a number of people,” he said.

Since the start of the year, authorities have recorded 50,840 mpox cases and 1,083 deaths across Africa.

Central Africa accounts for more than 85% of cases and almost all deaths.

The Democratic Republic of Congo, which has recorded more than 39,000 cases and more than 1,000 deaths since the start of the year, launched a vaccination campaign last month that is still “limited,” according to the Africa CDC.

Some 51,649 people have been vaccinated in six provinces, the Africa CDC said.

“We hope that with these vaccines we can continue to support countries to stop this outbreak,” Kaseya said.

Health agencies across the world have allocated just under 900,000 vaccine doses for nine African countries “hard hit by the current mpox surge,” the Africa CDC said in a statement Tuesday.

The countries include the DRC, Kenya and Uganda.

“The largest number of doses — 85% of the allocation — will go to the Democratic Republic of the Congo as the most affected country, reporting four out of every five laboratory confirmed cases in Africa this year,” the statement said.

Mpox, previously known as monkeypox, is caused by a virus transmitted to humans by infected animals but can also be passed from human to human through close physical contact.

It causes fever, muscular aches and large boil-like skin lesions, and can be deadly.

European climate agency says this will likely be the hottest year on record — again

CHICAGO — For the second year in a row, Earth will almost certainly be the hottest it’s ever been. And for the first time, the globe this year reached more than 1.5 degrees Celsius of warming compared to the pre-industrial average, the European climate agency Copernicus said Thursday.

“It’s this relentless nature of the warming that I think is worrying,” said Carlo Buontempo, director of Copernicus.

Buontempo said the data clearly shows the planet would not see such a long sequence of record-breaking temperatures without the constant increase of greenhouse gases in the atmosphere driving global warming.

He cited other factors that contribute to exceptionally warm years like last year and this one. They include El Nino — the temporary warming of parts of the Pacific that changes weather worldwide — as well as volcanic eruptions that spew water vapor into the air and variations in energy from the sun. But he and other scientists say the long-term increase in temperatures beyond fluctuations like El Nino is a bad sign.

“A very strong El Nino event is a sneak peek into what the new normal will be about a decade from now,” said Zeke Hausfather, a research scientist with the nonprofit Berkeley Earth.

News of a likely second year of record heat comes a day after Republican Donald Trump, who has called climate change a “hoax” and promised to boost oil drilling and production, was reelected to the U.S. presidency. It also comes days before the next U.N. climate conference, called COP29, is set to begin in Azerbaijan. Talks are expected to focus on how to generate trillions of dollars to help the world transition to clean energies like wind and solar, and thus avoid continued warming.

Buontempo pointed out that going over the 1.5 degree Celsius threshold of warming for a single year is different than the goal adopted in the 2015 Paris Agreement. That goal was meant to try to cap warming at 1.5 degrees Celsius since pre-industrial times on average, over 20 or 30 years.

A United Nations report this year said that since the mid-1800s on average, the world has already heated up 1.3 degrees Celsius — up from previous estimates of 1.1 degrees or 1.2 degrees. That’s of concern because the U.N. says the greenhouse gas emission reduction goals of the world’s nations still aren’t nearly ambitious enough to keep the 1.5 degree Celsius target on track.

The target was chosen to try to stave off the worst effects of climate change on humanity, including extreme weather. “The heat waves, storm damage, and droughts that we are experiencing now are just the tip of the iceberg,” said Natalie Mahowald, chair of Earth and Atmospheric Sciences at Cornell University.

Going over that number in 2024 doesn’t mean the overall trend line of global warming has, but “in the absence of concerted action, it soon will,” said University of Pennsylvania climate scientist Michael Mann.

Stanford University climate scientist Rob Jackson put it in starker terms. “I think we have missed the 1.5 degree window,” said Jackson, who chairs the Global Carbon Project, a group of scientists who track countries’ carbon dioxide emissions. “There’s too much warming.”

Indiana state climatologist Beth Hall said she isn’t surprised by the latest report from Copernicus, but emphasized that people should remember climate is a global issue beyond their local experiences with changing weather. “We tend to be siloed in our own individual world,” she said. Reports like this one “are taking into account lots and lots of locations that aren’t in our backyard.”

Buontempo stressed the importance of global observations, bolstered by international cooperation, that allow scientists to have confidence in the new report’s finding: Copernicus gets its results from billions of measurements from satellites, ships, aircraft and weather stations around the world.

He said that going over the 1.5 degree Celsius benchmark this year is “psychologically important” as nations make decisions internally and approach negotiations at the annual U.N. climate change summit Nov. 11-22 in Azerbaijan.

“The decision, clearly, is ours. It’s of each and every one of us. And it’s the decision of our society and our policymakers as a consequence of that,” he said. “But I believe these decisions are better made if they are based on evidence and facts.”

Vaccine doses allocated for 9 African countries hardest hit by mpox

An initial 899,000 vaccine doses have been allocated for nine countries across Africa that have been hit hard by the current mpox surge, the WHO and other health organizations said on Wednesday.

The WHO declared mpox a global public health emergency for the second time in two years in August after a new variant of the virus, called clade Ib, spread from the Democratic Republic of Congo to neighboring countries.

In September, after facing criticism on moving too slowly on vaccines, the World Health Organization cleared Bavarian Nordic’s BAVA.CO vaccine for mpox and said it was considering LC16, made by Japan’s KM Biologics as a potential vaccine option.

The WHO also set up a scheme to help bring mpox vaccines, tests and treatments to the most vulnerable people in the world’s poorest countries, similar to efforts during the COVID-19 pandemic.

The global health agency said on Wednesday the newly allocated vaccines will go to the Central African Republic, Ivory Coast, the Democratic Republic of Congo, Kenya, Liberia, Nigeria, Rwanda, South Africa and Uganda.

The largest number of doses – 85% of the allocated vaccines – will go to the Democratic Republic of Congo as the most affected country, the WHO said.

The allocated vaccines are from European countries, the United States, Canada and Gavi, a public-private alliance that co-funds vaccine purchases for low-income countries.

According to the latest WHO figures, there have been more than 46,000 confirmed and suspected cases of mpox in Africa this year, and more than 1,000 deaths in the continent due to the viral illness.

WHO: 2 UK mpox cases first local transmissions in Europe

London — Two new cases of the mpox variant clade 1b detected in the U.K. are the first locally transmitted cases in Europe and the first outside Africa, the World Health Organization said Tuesday.

The U.K. Health Security Agency (UKHSA) confirmed late Monday that the two new cases were household contacts of Britain’s first case identified last week, bringing the country’s total confirmed cases to three.

The WHO warned that European states should be prepared for “rapid action” to contain the latest mpox variant, which spreads through close physical contact including sexual relations and sharing closed spaces.

The two cases are also the first to be locally transmitted outside Africa since August 2024, when the WHO declared the outbreak of the new variant an international public health emergency — its highest level of alarm.

Those affected are under specialist care and the risk to the U.K. population “remains low,” UKHSA said.

The original case was detected after the person traveled to several African countries on holiday and returned to the U.K. on Oct. 21.

The patient developed flu-like symptoms more than 24 hours later and, on Oct. 24, started to develop a rash that worsened in the following days.

Mpox, a viral disease related to smallpox, has two types, clade 1 and clade 2. Symptoms include fever, a skin rash or pus-filled blisters, swollen lymph nodes and body aches.

The WHO first declared an international public health emergency in 2022 over the spread of clade 2. That outbreak mostly affected gay and bisexual men in Europe and the United States.

Vaccination and awareness drives in many countries helped stem the number of worldwide cases and the WHO lifted the emergency in May 2023 after reporting 140 deaths out of around 87,400 cases.

In 2024, a two-pronged epidemic of clade 1 and clade 1b, a new strain that affects children, has spread widely in the Democratic Republic of Congo.

The new strain has also been recorded in neighboring Burundi, Kenya, Rwanda and Uganda, with imported cases in Sweden, India, Thailand, Germany and the U.K.

WHO identifies priority pathogens for new vaccines development

Geneva — The World Health Organization on Tuesday listed 17 pathogens that cause widespread disease and death, including HIV, malaria and tuberculosis, for which it said new vaccines were “urgently needed.”

The U.N. health agency said that it with its list was providing the first global effort to systematically prioritize endemic pathogens based on criteria including disease burdens, antimicrobial resistance risk and the socioeconomic impact.

“We need to do this because we would like to shift the focus from developing vaccines away from commercial returns towards regional and global health needs,” Mateusz Hasso-Agopsowicz, a WHO vaccine specialist, told reporters in Geneva via video link from Poland.

The study reconfirms longstanding priorities for vaccine research and development, including HIV, malaria and tuberculosis — three diseases that collectively kill nearly 2.5 million people each year, WHO said.

But it also identifies lesser-known pathogens as top disease control priorities, highlighting the urgency to develop new vaccines for pathogens that are becoming increasingly resistant to antimicrobials.

Among them was Group A streptococcus, which causes severe infections and contributes to some 280,000 deaths from rheumatic heart disease each year, mainly in lower-income countries.

Ita also highlights the dangers of Klebsiella pneumoniae — a bacterium that is responsible for around 40% of neonatal deaths due to blood infection, or sepsis, in low-income countries.

These vaccines “would not only significantly reduce diseases that greatly impact communities today but also reduce the medical costs that families and health systems face,” WHO vaccine chief Kate O’Brien said in a statement.

Vaccines for the various pathogens listed are at different stages of development, WHO said, with some like ones for HIV, Group A streptococcus and hepatitis C virus still at the research stage. 

Others, like ones for dengue and tuberculosis, have been developed and are approaching regulatory approval or introduction.

Hasso-Agopsowicz explained that the 17 listed pathogens were wreaking the most havoc in lower-income countries, explaining why more progress has not been made previously on developing vaccines against them.

“What typically has happened in the past is that vaccine research and development has been influenced by profitability of new vaccines. What that means is that diseases that severely affect low-income regions unfortunately receive much less attention,” he said.

With the new list, he said, “we want to change the focus… so that the new vaccine research and development is driven by health burden and not just commercial opportunities.”

WHO continues talks to prepare world for pandemics

geneva — World Health Organization member countries resumed negotiations Monday to finalize an agreement on pandemic prevention, with outbreaks of mpox, Marburg and H5N1 stressing the urgency of reaching an agreement without repeating the deadly mistakes of COVID-19.

After more than two years of negotiations, there is hope of reaching an agreement in the next 15 days, especially since the negotiators have agreed to postpone discussions on the most contentious points: the sharing of knowledge and equitable access to medical advances.

Recent negotiations at COP16 in Colombia on biodiversity, which provided for a comparable mechanism, stumbled on this point.

WHO chief Tedros Adhanom Ghebreyesus stressed the need to balance timeliness and workable deal.

“Time is not our friend,” Tedros told national negotiators at the opening of the talks. “COVID is still circulating. Mpox is a global health emergency. We have a Marburg outbreak and H5N1 spreading. The next pandemic will not wait.”

Never again

In December 2021, fearing a repeat of the catastrophe caused by COVID-19, which killed millions of people, the 194 member countries of WHO agreed to reach an agreement on pandemic prevention, preparedness and response.

The emergence of a new strain of mpox, the deadly Marburg virus outbreak in Rwanda and the spread of H5N1 avian flu in recent months have clarified the issues.

Diplomats have agreed on most of the draft’s 37 articles during 11 rounds of negotiations.

The main section on which consensus will need to be found concerns access to pathogens for the scientific community and medical research, and then to products to combat the pandemic such as vaccines or other tests derived from this research.

In order not to block everything, the idea is to postpone the discussion on the details of the pathogen access and benefit sharing system (PABS) until later.

Battle for fairness

For the moment, there is an impasse between rich and poor countries, which have not forgotten that they were abandoned to their fate during the COVID-19 pandemic.

“If the world has failed on one thing, it is on the issue of equity” during the COVID-19 pandemic, the head of WHO stressed on Friday.

“Africa was left behind at the time, and this should not happen,” Tedros said.

‘Bitter taste’

Helen Clark, former New Zealand Prime Minister, believes that “the South sees the North as protecting its pharmaceutical industries,” and this “has left an incredibly bitter taste between the North and the South.”

The International Federation of Pharmaceutical Manufacturers and Associations called for an agreement “allowing the private sector to innovate.”

“Intellectual property must be respected, and technology transfer must always be voluntary and on mutually agreed terms,” the federation insisted.

Among the country representatives, Malaysia, speaking on behalf of a group of developing countries known as the Equity Group, said “major improvements are still desperately needed in many areas.”

It demanded that at least 20% of real-time production of vaccines, tests and treatments go to developing countries.

Tanzania, on behalf of 48 African countries, said it could not “accept an agreement not based on equity.”

The Indonesian negotiator said an agreement that only preserves the status quo is unacceptable, because “empty promises will not save lives.”

China insisted that “quality should not be sacrificed for time.”

Germany’s representative called for an acceleration of the talks to “focus on what is achievable.”

Public funding for nature conservation stalls at COP16, eyes on private investment

CALI, Colombia — Wealthy nations appeared to hit a limit with how much they are willing to pay to conserve nature around the world, instead shifting their focus at the two-week U.N. biodiversity summit toward discussions of private money filling the funding gap.

At the COP16 negotiations in Cali, Colombia, countries failed to figure out how they would mobilize $200 billion annually in conservation funding by 2030, including $30 billion that would come directly from rich nations.

That money, pledged two years ago as part of the landmark Kunming-Montreal Global Biodiversity Framework agreement, is meant to finance activities that boost nature, such as sustainable farming or patrolling wildlife reserves.

But there was no consensus as talks dragged on beyond the summit’s scheduled end on Friday, during which dozens of delegations departed. By Saturday morning’s roll call, there was no longer a quorum among the nearly 200 nations for an agreement to pass, forcing organizers to abruptly suspend the meeting.

“I am both saddened and enraged by the non-outcome of COP16,” said Shilps Gautam, chief executive of project finance firm Opna.

“The wild thing about the nature financing discussions is that the numbers discussed are already a pittance.”

Human activities such as farming, mining, and urban development are increasingly pushing nature into crisis, with 1 million or so plant and animal species thought to be at risk of extinction.

Climate change, a result of fossil fuel burning, is also adding to nature’s woes by raising temperatures and disrupting weather cycles.

Countries will meet again in Azerbaijan next week for the U.N.’s COP29 climate summit, which again will be focused on the steep need for funding from wealthy nations to their poorer counterparts to help shoulder climate costs.

Little money from rich nations

Even before the talks broke down, developed nations had signaled an unwillingness to offer large amounts of cash.

European governments including Germany and the Netherlands have slashed their foreign aid budgets over the last year, while France and the U.K. are also cutting back.

Government development money specifically targeted at nature conservation abroad fell to $3.8 billion in 2022 compared with $4.6 billion in 2015, according to the Organization for Economic Co-operation and Development.

At COP16, U.N. Secretary General Antonio Guterres demanded that countries make significant new contributions to the Global Biodiversity Framework Fund.

The response was muted. Nations at COP16 pledged $163 million in contributions to the fund, bringing total contributions to roughly $400 million – far from a major contribution to the $30 billion target from nations by 2030.

The United States, which is not a party to U.N. Convention on Biological Diversity, has not contributed.

“The public money is already leveraged as much as we can,” Florika Fink-Hooijer, the European Union’s director general of environment, told reporters at the summit.

“We now have to look at other sources of funding.”

Private cash

When it came to going after private capital, delegates at the COP16 summit agreed to a plan to charge pharmaceutical and other companies for their use of genetic information in the research and development of new commercial products.

Pharmaceutical companies Pfizer, Merck, AstraZeneca and Land Sanofi did not respond to request for comment on the deal.

Experts estimate the plan could generate about $1 billion annually.

That still doesn’t cover the billions needed to halt the collapse of ecosystems, like the Amazon rainforest or coral reefs. The world will need to devise ways for enticing private investment in nature-friendly projects, said Marcos Neto, director of global policy at the U.N. Development Program.

Some tools include green bonds or debt-for-nature swaps, whereby countries refinance their debt at lower interest rates in order to spend the savings on conservation. The World Economic Forum estimates that debt-for-nature swaps could generate $100 billion in nature funding.

Mpox cases in Congo may be stabilizing, but more vaccines needed to stamp out virus 

Goma, Congo — Some health officials say mpox cases in Congo appear to be “stabilizing” — a possible sign that the main epidemic for which the World Health Organization made a global emergency declaration in August might be on the decline.  

In recent weeks, Congo has reported about 200 to 300 lab-confirmed mpox cases every week, according to WHO. That’s down from nearly 400 cases a week in July. The decline is also apparent in Kamituga, the mining city in the eastern part of Congo where the new, more infectious variant of mpox first emerged.  

But the U.N. health agency acknowledged Friday that only 40% to 50% of suspected infections in Congo were being tested — and that the virus is continuing to spread in some parts of the country and elsewhere, including Uganda.  

While doctors are encouraged by the drop in infections in some parts of Congo, it’s still not clear what kinds of physical contact is driving the outbreak. Health experts are also frustrated by the low number of vaccine doses the central African nation has received — 265,000 — and say that delivering the vaccine to where it’s needed in the sprawling country is proving difficult. WHO estimates 50,000 people have been immunized in Congo, which has a population of 110 million.  

Scientists also say there needs to be an urgent, broader vaccination effort for the entire continent to halt mpox’s spread and avoid further worrisome genetic mutations, like the one detected earlier this year in Congo after months of low-level circulation.  

“If we miss this opportunity, the likelihood of another significant outbreak increases substantially,” said Dr. Zakary Rhissa, who heads operations in Congo for the charity Alima.  

So far this year, there have been roughly 43,000 suspected cases in Africa and more than 1,000 people have died, mostly in Congo.  

“We’ve seen how past outbreaks, such as the one in Nigeria in 2017, can lead to larger global events if not effectively contained,” he said. The 2017 epidemic ended up leading to the 2022 global outbreak of mpox that affected more than 100 countries.  

Rhissa said the decline in cases in Kamituga — where mpox initially spread among sex workers and miners — is an opening to put more programs in place for vaccination, surveillance and education.  

Georgette Hamuli, an 18-year-old sex worker, hadn’t been aware of mpox until immunization teams arrived last week in the poor neighborhood where she works in Goma, the biggest city in eastern Congo.  

“They told us we’re highly exposed to the risk of infection,” she said. “We insist on condoms with our clients, but some refuse … if they don’t want to use a condom, they double the amount they pay.”  

Hamuli said she and other friends who are sex workers each received 2,000 Congolese francs ($0.70) from a charity to get vaccinated against mpox — but it wasn’t the money that swayed her. 

“The vaccine is also necessary,” she said. “I think we’re now protected.”   

The Africa Centers for Disease Control and Prevention has estimated Congo needs at least 3 million mpox vaccines to stop the virus, and another 7 million for the rest of Africa. So far, WHO and partners have allocated 900,000 vaccines to nine African countries affected by mpox and expect 6 million vaccines to be available by the end of this year.  

Mpox epidemics in Burundi, Kenya, Rwanda and Uganda had their origins in Congo, and a number of cases in travelers have also been identified in Sweden, Thailand, Germany, India and Britain.  

Fewer than half of the people who are most at risk in Congo have been vaccinated, according to Heather Kerr, Congo director for the International Rescue Committee.  

“We only have a tiny amount of vaccines, and nothing for the kids,” she said.  

The vaccines for Congo are largely coming from donor countries like the U.S and through UNICEF, which mainly uses taxpayer money to buy the shots.  

“We’re getting a charitable approach where we only see very small donations of vaccines to Africa,” said Dr. Chris Beyrer, director of the Global Health Institute at Duke University. “What we need is a public health approach where we immunize populations at scale.”  

Drugmaker Bavarian Nordic, which makes the most widely used mpox vaccine, said it would sell shots destined for Africa at the lowest price possible.  

The advocacy group Public Citizen estimated UNICEF paid $65 per dose of the Jynneos mpox vaccine made by Bavarian Nordic, far higher than nearly all other vaccines used in public health programs. 

Dr. Salim Abdool Karim, an infectious diseases expert at South Africa’s University of KwaZulu-Natal, said mpox outbreaks typically peak and disappear quickly because of how the virus spreads. This time, however, he said there are two complicating factors: the virus’ transmission via sex and the continued spillover from infected animals.  

“We’re in new territory with mpox this time,” he added. “But we’re never going to solve this until we vaccinate most of our people.”

Lahore air pollution hits historic high, forcing school closures 

KARACHI — Unprecedented air pollution levels in Pakistan’s second-largest city of Lahore prompted authorities to take emergency measures on Sunday, including issuing work-from-home mandates and closing primary schools.  

The city held the top spot on a real-time list of the world’s most polluted cities on Sunday after recording its highest ever pollution reading of 1900 near the Pakistan-India border on Saturday, based on data released by the provincial government and Swiss group IQAir.  

The government has shut primary schools for a week, advising parents to ensure children wear masks, said Senior Minister of Punjab Marriyum Aurangzeb during a press conference, as a thick blanket of smog enveloped the city.  

Citizens have been urged to stay indoors, keep doors and windows shut, and avoid unnecessary travel, she said, adding that hospitals had been given smog counters.  

To reduce vehicle pollution, 50% of office employees would work from home, said Aurangzeb.  

The government has also imposed a ban on three-wheelers known as rickshaws and halted construction in certain areas to reduce the pollution levels. Factories and construction sites failing to comply with these regulations could be shut down, she said.  

Aurangzeb described the situation as “unexpected” and attributed the deterioration in air quality to winds carrying pollution from neighboring India.   

“This cannot be solved without talks with India,” she said, adding the provincial government would initiate talks with its bigger neighbor through Pakistan’s foreign ministry.   

The smog crisis in Lahore, similar to the situation in India’s capital Delhi, tends to worsen during cooler months due to temperature inversion trapping pollution closer to the ground.

Will people leave Florida after devastating hurricanes? History suggests not

orlando, florida — The news rippled through Treasure Island, Florida, almost like a third storm: The mayor planned to move off the barrier island a month after Hurricane Helene flooded tens of thousands of homes along the Gulf Coast and two weeks after Hurricane Milton also ravaged the state. 

Mayor Tyler Payne’s home had been flooded and damaged beyond repair, he explained in a message to Treasure Island residents, and he and his husband can’t afford to rebuild. He also was stepping down as mayor. 

“While it pains my heart to make this decision in the midst of our recovery from Hurricanes Helene and Milton, this is the best decision for me and my family,” Payne, who had held the office for more than three years and was a fourth-generation Treasure Island resident, said Monday. 

Up and down Florida’s storm-battered Gulf Coast, residents are making the same calculations about whether they should stay or go. Can they afford to rebuild? What will insurance cover? People considering moving to Florida are contemplating whether it’s worth the risk to come to a hurricane-prone state. 

These existential questions about Florida’s appeal are raised regularly after the state experiences a busy hurricane season, such as in 2004, when four hurricanes crossed the Sunshine State. 

 

If moves into the state offer any answer, then hurricanes have served little as deterrents. Florida’s population has grown by one-third to 23 million residents in the two decades since Charley, Frances, Jeanne and Ivan ravaged the state. Last year, Florida added more than 365,000 residents, second only to Texas among states. 

On the other hand, there are signs that Florida’s white-hot real estate market has cooled. Sales of single-family homes were down 12% in September compared with the same time in the previous year. But interest rates, rising home prices and skyrocketing insurance costs likely played bigger roles than the recent hurricanes. 

“Florida recovers much faster than you think,” said Brad O’Connor, chief economist for Florida Realtors. 

What happens after a storm? 

Studies of hurricanes along the Gulf Coast have shown that any outbound migration tends to be short-lived, and if people do leave, it’s usually a short-distance move, such as from a barrier island to the mainland. Older people with more financial resources are more likely to return to devastated communities. 

When it comes to the housing market, there may be an initial shock to the supply as homeowners wait for reimbursement from insurance companies to fix up their homes or sell them. 

But in the three years after a hurricane, home prices in areas of Florida that were hit by one are 5% higher on average than elsewhere in the state because of smaller supply, according to a study of the impact of hurricanes on Florida’s housing market from 2000 to 2016. New homeowners tend to be richer than previous ones because wealthier buyers can absorb price increases. 

Other factors that determine how quickly communities bounce back include whether homes were insured, the speed of insurance reimbursements, and whether there are enough construction workers. Because of stricter building codes implemented in the years after Hurricane Andrew devastated South Florida in 1992, newer homes withstand hurricanes better than older ones, O’Connor said. 

“If a property is damaged and uninsured, and the homeowner says, ‘I don’t want to deal with this,’ there are always people willing to scoop up that property because it’s valuable land,” he said. “People build new homes under the new codes and there’s less of an impact from hurricanes.” 

Short term and long term 

Recent storms offer examples what happens to communities, both short term and longer term. 

In Lee County, home to Fort Myers, Hurricane Ian made landfall two years ago in what had been one of the fastest growing parts of the United States. Population growth slowed afterward to 1.5% from 4.4% before the storm. The number of households dropped from about 340,000 to about 326,000, according to the U.S. Census Bureau. 

In 2019, three-quarters of all United Van Lines truck moves were into Lee County and a quarter were outbound, but that dropped to two-thirds inbound and a third outbound in 2023 to 2024, the company told The Associated Press. 

The share of people in their late 20s, 30s and early 40s increased, as did the share of men with no spouse or partner, reflecting an influx of construction and recovery workers. The share of the white population dropped while it increased for the Hispanic community. The percentage of utility and transportation workers in the county jumped, according to the Census Bureau. 

Bay County in the Florida Panhandle, where Michael made landfall as the first Category 5 hurricane on the continental U.S. in a quarter century in 2018, offers a portrait of longer term trends. Four years later, Bay County had recovered its pre-hurricane population, which dropped almost 6% in the year after the storm. 

Since Michael, the county has grown more diverse, wealthier and older, with the median age rising from 39.6 to 41.4 and more people identifying as multiracial or Hispanic. The share of households earning $200,000 or more went from 4.3% before the hurricane to 8.3% in 2022 in a sign that some of the least affluent residents couldn’t afford to rebuild or return. 

Treasure Island’s mayor 

In his message to constituents, Payne said he would still stay connected to the Treasure Island community because his parents plan to rebuild on the barrier island, one of a string of beach towns along the Gulf of Mexico west of St. Petersburg known for motels, restaurants and bars lining the street. Payne, an attorney who also is an executive in his family’s eyeglass-lens manufacturing business, said in his message that his decision to move was “difficult.” 

“I completely empathize with the difficult decisions that are facing so many of our residents,” he said.
