Blantyre, Malawi     — Malawi has declared the end of the country’s worst cholera outbreak, which began in March 2022 and killed nearly 2,000 people.

In a statement Monday, the Ministry of Health said the country had registered no cases or deaths from cholera in 26 of Malawi’s 29 health districts in the past four weeks. Some health experts, however, said the outbreak could resurface if the country failed to address sanitation problems that caused it.

Malawi President Lazarus Chakwera launched a national campaign to end the cholera outbreak in February 2023. The “Tithetse Kolera” or “Let’s End Cholera” campaign came three months after he declared the disease to be a public health emergency in Malawi.

The campaign aimed to interrupt cholera transmission in all districts and reduce the fatality rate from 3.2% to below 1%, which the World Health Organization considers a controlled cholera outbreak.

Dr. Wilfred Chalamira Nkhoma,  co-chairperson for the presidential task force on COVID-19 and cholera in Malawi, told VOA the disease had now been defeated largely because of the campaign.

“By WHO definition, a country stands to end the transmission of cholera when they have gone at least four weeks without reporting a laboratory confirmed case of cholera,” he said. “So that is the case with Malawi right now. We haven’t had a confirmed case since 6th of June.”

Successful steps

Nkhoma attributed the development to several interventions Malawi conducted over the past two years. He said they involved educating people about transmission, prevention and control of cholera; increasing surveillance; and properly managing cholera cases.

“The key one — and that must remain the key one — is to increase access to safe water and also improve adequate sanitation,” he said. “The Ministry of Water and Sanitation was taking the lead in this, but they were supported very well by nongovernmental organizations that are working in the water and sanitation sector.”

Nkhoma said another measure was the oral cholera vaccination campaign, which began in December 2022.

“We were able as a country to access some doses from WHO,” he said. “We were able to administer not less than about  6 million doses of cholera vaccine focusing first and foremost in priority areas.”

The Ministry of Health said in its Monday statement that Malawi had registered 56,376 cases of cholera, with 1,772 deaths since March 2022.

Maziko Matemba, a national community health ambassador in Malawi, told VOA that Malawi seemed to have managed the cholera outbreak at the treatment and case-management levels, but added that sanitation problems remained a challenge.

“Because at the moment, if you go to villages, if you go to public places, people are not doing the sanitation issues properly,” Matemba said. “Even if you check in public toilets, even if you check how people are preparing food, you will find that we still have challenges as a country to contain disease like cholera.” 

Nkhoma said the government would continue its effort to educate people about how cholera is transmitted, prevented and controlled to try to avoid further outbreaks.

LONDON — The world’s second vaccine against malaria was launched on Monday as Ivory Coast began a routine vaccine program using shots developed by the University of Oxford and the Serum Institute of India. 

The introduction of the World Health Organization (WHO)-approved R21 vaccine comes six months after the first malaria vaccine, called RTS,S and developed by British drugmaker GSK, began being administered in a routine program in Cameroon. 

Some 15 African countries plan to introduce one of the two malaria vaccines this year with support from the Gavi global vaccine alliance. 

Ivory Coast has received a total of 656,600 doses of the Oxford and Serum shot, which will initially vaccinate 250,000 children aged between 0 and 23 months across the West African country. The vaccine has also been approved by Ghana, Nigeria, Burkina Faso and the Central African Republic. 

The rollout of a second vaccine is the latest milestone in the global fight against malaria and should help address a problem that emerged well before either of the two shots was launched: demand for them is likely to far outstrip supply for several years. 

Experts say having safe and effective malaria vaccines is important to meet demand. The shot is meant to work alongside existing tools — such as bed nets — to combat malaria, which in Africa kills nearly half a million children under the age of five each year. 

The Serum Institute of India, which manufactures the vaccine, has produced 25 million doses for the initial rollout of the shot and “is committed to scaling up to 100 million doses annually,” the company said on Monday about the launch in Ivory Coast. 

Serum said it is offering the vaccine for less than $4 per dose, in keeping with its aim to deliver low-cost vaccines at scale. 

Results from a large trial in February showed the vaccine prevented around three-quarters of symptomatic malaria cases in young children the first year after they got the shots. 

Experts told Reuters at that time that comparing the two malaria vaccines head-to-head was difficult because of the many variables involved in the trials, but overall their performance was similar — a conclusion endorsed by WHO.

CAPE CANAVERAL, Fla. — Scientists have confirmed a cave on the moon, not far from where Neil Armstrong and Buzz Aldrin landed 55 years ago, and suspect there are hundreds more that could house future astronauts.

An Italian-led team reported Monday that there’s evidence for a sizable cave accessible from the deepest known pit on the moon. It’s located at the Sea of Tranquility, just 250 miles (400 kilometers) from Apollo 11’s landing site.

The pit, like the more than 200 others discovered up there, was created by the collapse of a lava tube.

Researchers analyzed radar measurements by NASA’s Lunar Reconnaissance Orbiter, and compared the results with lava tubes on Earth. Their findings appeared in the journal Nature Astronomy.

Northern Ukraine — Struggling with manpower shortages, overwhelming odds and uneven international assistance, Ukraine hopes to find a strategic edge against Russia in an abandoned warehouse or a factory basement.

An ecosystem of laboratories in hundreds of secret workshops is leveraging innovation to create a robot army that Ukraine hopes will kill Russian troops and save its own wounded soldiers and civilians.

Defense startups across Ukraine — about 250 according to industry estimates — are creating the killing machines at secret locations that typically look like rural car repair shops.

Employees at a startup run by entrepreneur Andrii Denysenko can put together an unmanned ground vehicle called the Odyssey in four days at a shed used by the company. Its most important feature is the price tag: $35,000, or roughly 10% of the cost of an imported model.

Denysenko asked that The Associated Press not publish details of the location to protect the infrastructure and the people working there.

The site is partitioned into small rooms for welding and body work. That includes making fiberglass cargo beds, spray-painting the vehicles gun-green and fitting basic electronics, battery-powered engines, off-the-shelf cameras and thermal sensors.

The military is assessing dozens of new unmanned air, ground and marine vehicles produced by the no-frills startup sector, whose production methods are far removed from giant Western defense companies.

A fourth branch of Ukraine’s military — the Unmanned Systems Forces — joined the army, navy and air force in May.

Engineers take inspiration from articles in defense magazines or online videos to produce cut-price platforms. Weapons or smart components can be added later.

“We are fighting a huge country, and they don’t have any resource limits. We understand that we cannot spend a lot of human lives,” said Denysenko, who heads the defense startup UkrPrototyp. “War is mathematics.”

One of its drones, the car-sized Odyssey, spun on its axis and kicked up dust as it rumbled forward in a cornfield in the north of the country last month.

The 800-kilogram (1,750-pound) prototype that looks like a small, turretless tank with its wheels on tracks can travel up to 30 kilometers (18.5 miles) on one charge of a battery the size of a small beer cooler.

The prototype acts as a rescue-and-supply platform but can be modified to carry a remotely operated heavy machine gun or sling mine-clearing charges.

“Squads of robots … will become logistics devices, tow trucks, minelayers and deminers, as well as self-destructive robots,” a government fundraising page said after the launch of Ukraine’s Unmanned Systems Forces. “The first robots are already proving their effectiveness on the battlefield.”

Mykhailo Fedorov, the deputy prime minister for digital transformation, is encouraging citizens to take free online courses and assemble aerial drones at home. He wants Ukrainians to make a million of flying machines a year.

“There will be more of them soon,” the fundraising page said. “Many more.”

Denysenko’s company is working on projects including a motorized exoskeleton that would boost a soldier’s strength and carrier vehicles to transport a soldier’s equipment and even help them up an incline. “We will do everything to make unmanned technologies develop even faster. [Russia’s] murderers use their soldiers as cannon fodder, while we lose our best people,” Fedorov wrote in an online post.

Ukraine has semi-autonomous attack drones and counter-drone weapons endowed with AI and the combination of low-cost weapons and artificial intelligence tools is worrying many experts who say low-cost drones will enable their proliferation.

Technology leaders to the United Nations and the Vatican worry that the use of drones and AI in weapons could reduce the barrier to killing and dramatically escalate conflicts.

Human Rights Watch and other international rights groups are calling for a ban on weapons that exclude human decision making, a concern echoed by the U.N. General Assembly, Elon Musk and the founders of the Google-owned, London-based startup DeepMind.

“Cheaper drones will enable their proliferation,” said Toby Walsh, professor of artificial intelligence at the University of New South Wales in Sydney, Australia. “Their autonomy is also only likely to increase.”

Geneva — Global childhood vaccination levels have stalled, leaving millions more children un- or under-vaccinated than before the pandemic, the U.N. said Monday, warning of dangerous coverage gaps enabling outbreaks of diseases like measles.

In 2023, 84% of children, or 108 million, received three doses of the vaccine against diphtheria, tetanus and pertussis (DTP), with the third dose serving as a key marker for global immunization coverage, according to data published by the U.N. health and children’s agencies.

That was the same percentage as a year earlier, meaning that modest progress seen in 2022 after the steep drop during the COVID-19 crisis has “stalled,” the organizations warned. The rate was 86% in 2019 before the pandemic.

“The latest trends demonstrate that many countries continue to miss far too many children,” UNICEF chief Catherine Russell said in a joint statement.

In fact, 2.7 million additional children remained un- or under-vaccinated last year compared to the pre-pandemic levels in 2019, the organizations found.

‘Off track’

“We are off track,” World Health Organization vaccine chief Kate O’Brien told reporters. “Global immunization coverage has yet to fully recover from the historic backsliding that we saw during the course of the pandemic.”

Not only has progress stalled, but the number of so-called zero-dose children, who have not received a single jab, rose to 14.5 million last year from 13.9 million in 2022 and from 12.8 million in 2019, according to the data published Monday.

“This puts the lives of the most vulnerable children at risk,” O’Brien warned.

Even more concerning is that more than half of the world’s unvaccinated children live in 31 countries with fragile, conflict-affected settings, where they are especially vulnerable to contracting preventable diseases, due to lacking access to security, nutrition and health services.

Children in such countries are also far more likely to miss out on the necessary follow-up jabs.

A full 6.5 million children worldwide did not complete their third dose of the DTP vaccine, which is necessary to achieve disease protection in infancy and early childhood, Monday’s datasets showed. 

‘Canary in the coal mine’

The WHO and UNICEF voiced additional concern over lagging vaccination against measles — one of the world’s most infectious diseases — amid an exploding number of outbreaks around the world.

“Measles outbreaks are the canary in the coal mine, exposing and exploiting gaps in immunization and hitting the most vulnerable first,” WHO chief Tedros Adhanom Ghebreyesus said in the statement.

In 2023, only 83% of children worldwide received their first dose of the measles vaccine through routine health services — the same level as in 2022 but down from 86% before the pandemic.

And only 74% received their second necessary dose, while 95% coverage is needed to prevent outbreaks, the organizations pointed out.

“This is still too low to prevent outbreaks and achieve elimination goals,” Ephrem Lemango, UNICEF immunization chief, told reporters.

He pointed out that more than 300,000 measles cases were confirmed in 2023 — nearly three times as many as a year earlier.

And a full 103 countries have suffered outbreaks in the past five years, with low vaccination coverage of 80% or lower seen as a major factor.

By contrast, 91 countries with strong measles vaccine coverage experienced no outbreaks.

“Alarmingly, nearly three in four infants live in places at the greatest risk of measles outbreaks,” Lemango said, pointing out that 10 crisis-wracked countries, including Sudan, Yemen and Afghanistan, account for more than half of children not vaccinated against measles.

On a more positive note, strong increases were seen in vaccination against the cervical cancer-causing HPV virus.

But that vaccine is still only reaching 56% of adolescent girls in high-income countries and 23% in lower-income countries — far below the 90% target.
