The first Native American woman in space said Wednesday she is overwhelmed by the beauty and delicacy of Mother Earth and is channeling “positive energy” as her five-month mission gets underway.

NASA astronaut Nicole Mann said from the International Space Station that she’s received lots of prayers and blessings from her family and tribal community. She is a member of the Wailacki of the Round Valley Indian Tribes in Northern California.

Mann showed off the dream catcher she took up with her, a childhood gift from her mother that she’s always held dear. The small traditional webbed hoop with feathers is used to offer protection, and she said it’s given her strength during challenging times. Years before joining NASA in 2013, she flew combat in Iraq for the Marines.

“It’s the strength to know that I have the support of my family and community back home and that when things are difficult or things are getting hard or I’m getting burned out or frustrated, that strength is something that I will draw on to continue toward a successful mission,” Mann told The Associated Press, which gathered questions from members and tribal news outlets across the country.

Mann said she’s always heeded her mother’s advice on the importance of positive energy, especially on launch day.

“It’s difficult for some people maybe to understand because it’s not really tangible,” she said. “But that positive energy is so important, and you can control that energy, and it helps to control your attitude.”

Mann, 45, a Marine colonel and test pilot who was born in Petaluma, California, said it’s important to recognize there are all types of people aboard the space station. It’s currently home to three Americans, three Russians and one Japanese astronaut.

“What that does is it just highlights our diversity and how incredible it is when we come together as a human species, the wonderful things that we can do and that we can accomplish,” she said.

While fascinated with stars and space as a child, Mann said she did not understand who became astronauts or even what they did.

“Unfortunately, in my mind at that time, it was not in the realm of possibilities,” she said.

Now, she’s taking in the sweeping vistas of Earth from 260 miles (420 kilometers) up and hoping to see the constellations as she encourages youngsters to follow their dreams.

As for describing Earth from space, “the emotions are absolutely overwhelming,” she said. “It is an incredible scene of color, of clouds and land, and it’s difficult not to stay in the cupola (lookout) all day and just see our planet Earth and how beautiful she is, and how delicate and fragile she is against the blackest of black that I’ve ever seen — space — in the background.”

Mann rocketed into orbit with SpaceX on October 5. She’ll be up there until March. She and her husband, a retired Navy fighter pilot, have a 10-year-old son back home in Houston.

The first Native American in space, in 2002, was now-retired astronaut John Herrington of the Chickasaw Nation.

The World Health Organization said Wednesday it is too early to lift the highest-level alert for the COVID-19 crisis, with the pandemic remaining a global health emergency despite recent progress.

The WHO’s emergency committee on COVID-19 met last week and concluded that the pandemic still constitutes a Public Health Emergency of International Concern (PHEIC), a status it declared back in January 2020.

WHO chief Tedros Adhanom Ghebreyesus told reporters Wednesday that he agreed with the committee’s advice.

“The committee emphasized the need to strengthen surveillance and expand access to tests, treatments and vaccines for those most at risk,” he said, speaking from the UN health agency’s headquarters in Geneva.

The WHO first declared the COVID-19 outbreak a PHEIC on January 30, 2020, when, outside of China, fewer than 100 cases and no deaths had been reported.

Although declaration of a PHEIC is the internationally agreed mechanism for triggering an international response to such outbreaks, it was only in March, when Tedros described the worsening situation as a pandemic, that many countries woke up to the danger.

Since the start of the COVID-19 pandemic, more than 622 million confirmed COVID-19 cases have been reported to WHO and more than 6.5 million deaths, although those numbers are believed to be significant underestimates.

According to WHO’s global dashboard, 263,000 new cases were reported in the previous 24 hours, while 856 new COVID-19 deaths had been reported in the past week.

Tedros acknowledged Wednesday that “the global situation has obviously improved since the pandemic began,” but warned that “the virus continues to change and there remain many risks and uncertainties.”

“The pandemic has surprised us before and very well could again,” he warned.

‘Surveillance has declined’

Maria Van Kerkhove, the WHO’s COVID-19 technical lead, agreed, warning that there were still “millions of cases being reported each week, but our surveillance has declined.”

That decline is making it difficult to get a full overview of the situation and especially of how the virus is mutating. Van Kerkhove stressed that “the more this virus circulates, the more opportunities it has to change.”

The omicron variant accounts for basically all virus samples that are sequenced, with more than 300 sublineages of that variant recorded.

“All of the subvariants of omicron are showing increased transmissibility and properties of immune escape,” Van Kerkove said, adding that one new combination of two different subvariants was showing “significant immune evasion.”

“This is a concern for us because we need to ensure that the vaccines that are in use worldwide remain effective at preventing severe disease and death,” she said.

In light of the broad spread of new omicron subvariants, Van Kerkhove stressed that “countries need to be in a position to conduct surveillance to deal with increases in cases and perhaps deal with increases in hospitalizations.”

“We have to remain vigilant.”

The World Health Organization said on Wednesday it will temporarily suspend the standard two-dose vaccination regimen for cholera, replacing it with a single dose due to vaccine shortages and rising outbreaks worldwide. 

The U.N. agency said “the exceptional decision reflects the grave state of the cholera vaccine stockpile” at a time when countries like Haiti, Syria and Malawi are fighting large outbreaks of the deadly disease, which spreads through contact with contaminated water and food. 

As of October 9, Haiti had confirmed 32 cases and 18 deaths from the disease, while many cases were still awaiting confirmation. 

“The pivot in strategy will allow for the doses to be used in more countries, at a time of unprecedented rise in cholera outbreaks worldwide,” WHO said in a statement on Wednesday. 

The WHO’s emergencies director Mike Ryan told reporters in a briefing that the change in strategy was a sign of the “scale of the crisis” caused by a lack of focus on safe sanitation and immunization for all at risk. 

“It’s a sad day for us to have to go backwards,” he said. 

The one-dose strategy had proved to be effective as a response to cholera outbreaks, the agency said, although the duration of protection is limited and appears to be much lower in children. 

The disease often causes no or mild symptoms, but serious cases cause acute diarrhea and can kill within hours if untreated. 

Cholera cases have surged this year, especially in places of poverty and conflict, with outbreaks reported in 29 countries and fatality rates rising sharply. The WHO also said that climate change means that cholera is a risk in an increasing number of countries, as the bacteria causing the illness multiplies faster in warmer waters. 

A cholera outbreak in Syria has already killed at least 33 people, posing a danger across the frontlines of the country’s 11-year war and stirring fears in crowded camps for the displaced. 

A cholera outbreak in a north Cameroon refugee camp has killed three people and infected at least 36, the UN refugee agency said on Wednesday. 

The first case was confirmed on Saturday in the Minawao refugee camp, which hosts around 75,000 people who fled Boko Haram insurgents in neighboring Nigeria.

Experts say record-breaking floods in Australia are allowing mosquitoes to thrive, increasing the risk of spreading diseases like Japanese Encephalitis.

Communities across three states have in recent days been hit by flooding, and more torrential rain is forecast this week. Parts of eastern Australia have been repeatedly flooded in the past two-years.

Mosquitoes need stagnant water. Immature insects emerge from eggs and develop underwater until they become pupae, and then adults. Females require blood before laying eggs and can inject saliva and virus into humans when they bite.

Mosquito-borne diseases are a perennial problem in Australia, where thousands of people are infected with the Ross River virus each year.

In 2021, Japanese Encephalitis gained a significant foothold in Australia for the first time.

More than 40 people were infected with the virus, and seven people died, according to government data.

The virus moves between mosquitos and water birds. Pigs, too, can also harbor the virus.

The illness it causes can be mild, but in some cases, patients can suffer seizures.

Experts have said that fewer than one percent of people infected will develop a severe brain condition — called encephalitis — which can be fatal.

Associate Professor Cameron Webb from the New South Wales Health Department told the Australian Broadcasting Corp. that recent flooding increases the risk of Japanese encephalitis infection.

“There [are] hundreds of different types of mosquitos in Australia, but there is one mosquito in particular that we are concerned about when it comes to Japanese encephalitis virus,” he said. “It is a mosquito that thrives in freshwater environments, the type of environments that have been created by excessive rainfall and flooding across much of the country.”

Two naturally occurring climatic phenomena — La Niña and the Indian Ocean Dipole — are fueling the flooding. Experts have said that their impact is being intensified by climate change.

Australian troops and residents have been racing to build a two kilometers long levee to stop floodwaters from inundating the town of Echuca, north of Melbourne. Parts of eastern Australia have had their worst flooding in decades.

With heavy rain in the forecast later this week, regions from Queensland to Tasmania in eastern Australia are once again on flood watch.

A warming climate could bring viruses in the Arctic into contact with new environments and hosts, increasing the risk of “viral spillover,” according to research published Wednesday.

Viruses need hosts like humans, animals, plants or fungi to replicate and spread, and occasionally they can jump to a new one that lacks immunity, as seen during the COVID-19 pandemic.

Scientists in Canada wanted to investigate how climate change might affect spillover risk by examining samples from the Arctic landscape of Lake Hazen.

It is the largest lake in the world entirely north of the Arctic Circle and “was truly unlike any other place I’ve been,” researcher Graham Colby, now a medical student at the University of Toronto, told AFP.

The team sampled soil that becomes a riverbed for melted glacier water in the summer, as well as the lakebed itself — which required clearing snow and drilling through 2 meters of ice, even in May when the research was carried out.

They used ropes and a snowmobile to lift the lake sediment through almost 300 meters of water, and samples were then sequenced for DNA and RNA, the genetic blueprints and messengers of life.

“This enabled us to know what viruses are in a given environment, and what potential hosts are also present,” said Stephane Aris-Brosou, an associate professor in the University of Ottawa’s biology department, who led the work.

But to find out how likely they were to jump hosts, the team needed to examine the equivalent of each virus and host’s family tree.

“Basically, what we tried to do is measure how similar these trees are,” said Audree Lemieux, first author of the research.

Similar genealogies suggest a virus has evolved along with its host, but differences suggest spillover. And if a virus has jumped hosts once, it is more likely to do so again.

‘Very unpredictable’

The analysis found pronounced differences between viruses and hosts in the lakebed, “which is directly correlated to the risk of spillover,” said Aris-Brosou.

The difference was less stark in the riverbeds, which the researchers theorize is because water erodes the topsoil, removing organisms and limiting interactions between viruses and potential new hosts.

Those, instead, wash into the lake, which has seen “dramatic change” in recent years, the study says, as increased water from melting glaciers deposits more sediment.

“That’s going to bring together hosts and viruses that would not normally encounter each other,” Lemieux said.

The authors of the research, published in the Proceedings of the Royal Society B: Biological Sciences journal, caution they are neither forecasting an actual spillover nor a pandemic.

“The likelihood of dramatic events remains very low,” Lemieux said.

They also warn more work is needed to clarify how big the difference between viruses and hosts needs to be to create serious spillover risk.

But they argue that warming weather could increase risks further if new potential hosts move into previously inhospitable regions.

“It could be anything from ticks to mosquitoes to certain animals, to bacteria and viruses themselves,” said Lemieux.

“It’s really unpredictable … and the effect of spillover itself is very unpredictable. It can range from benign to an actual pandemic.”

The team wants more research and surveillance work in the region to understand the risks.

“Obviously, we’ve seen in the past two years what the effects of spillover can be,” said Lemieux.
