CAPE CANAVERAL, Florida — Boeing will attempt to return its problem-plagued capsule from the International Space Station later this week — with empty seats.

NASA said Wednesday that everything is on track for the Starliner capsule to undock from the space station Friday evening. The fully automated capsule will aim for a touchdown in New Mexico’s White Sands Missile Range six hours later.

NASA’s two stuck astronauts, who flew up on Starliner, will remain behind at the orbiting lab. They’ll ride home with SpaceX in February, eight months after launching on what should have been a weeklong test flight. Thruster trouble and helium leaks kept delaying their return until NASA decided that it was too risky for them to accompany Starliner back as originally planned.

“It’s been a journey to get here, and we’re excited to have Starliner return,” said NASA’s commercial crew program manager Steve Stich.

NASA’s Butch Wilmore and Suni Williams will close the hatches between Starliner and the space station on Thursday. They are now considered full-time station crew members along with the seven others on board, helping with experiments and maintenance, and ramping up their exercise to keep their bones and muscles strong during their prolonged exposure to weightlessness.

To make room for them on SpaceX’s next taxi flight, the Dragon capsule will launch with two astronauts instead of the usual four. Two were cut late last week from the six-month expedition, which is due to blast off in late September. Boeing must vacate the parking place for SpaceX’s arrival.

Boeing encountered serious flaws with Starliner long before its June 5 liftoff on the long-delayed astronaut demo.

Starliner’s first test flight went so poorly in 2019 — the capsule never reached the space station because of software errors — that the mission was repeated three years later. More problems surfaced, resulting in even more delays and more than $1 billion in repairs.

The capsule had suffered multiple thruster failures and propulsion-system helium leaks by the time it pulled up at the space station after launch. Boeing conducted extensive thruster tests in space and on the ground, and contended the capsule could safely bring the astronauts back. But NASA disagreed, setting the complex ride swap in motion.

Starliner will make a faster, simpler getaway than planned, using springs to push away from the space station and then short thruster firings to gradually increase the distance. The original plan called for an hour of dallying near the station, mostly for picture-taking; that was cut to 20 or so minutes to reduce the stress on the capsule’s thrusters and keep the station safe.

Additional test firings of Starliner’s 28 thrusters are planned before the all-important descent from orbit. Engineers want to learn as much as they can since the thrusters won’t return to Earth; the section containing them will be ditched before the capsule reenters.

The stuck astronauts — retired Navy captains — have lived on the space station before and settled in just fine, according to NASA officials. Even though their mission focus has changed, “they’re just as dedicated for the success of human spaceflight going forward,” flight director Anthony Vareha said.

Their blue Boeing spacesuits will return with the capsule, along with some old station equipment.

NASA hired Boeing and SpaceX a decade ago to ferry its astronauts to and from the space station after its shuttles retired. SpaceX accomplished the feat in 2020 and has since launched nine crews for NASA and four for private customers.

SYDNEY — Global concerns over plastic pollution and cuts to fossil fuel use are behind a new Australian-led initiative to develop a new generation of 100 percent compostable plastic. Experts estimate that more than 170 trillion pieces of plastic are floating in the world’s oceans. There are growing concerns about the impact of micro-plastics on health and the environment.    

The Bioplastics Innovation Hub aims to “revolutionize” plastic packaging by making biologically-made plastic that can break down in compost, land or water.  

The aim is to produce water bottles, for example, using bioplastics derived from waste products from the food industry. 

The green plastic scheme brings together the Commonwealth Scientific and Industrial Research Organization, the CSIRO – Australia’s national science agency – and Murdoch University in Perth in a multi-million dollar collaboration with industry partners. 

Andrew Whiteley, a CSIRO research program director, told VOA the technology could be ground-breaking.

“What we are really essentially doing is trying to phase out those fossil fuel plastics and bring in this new generation of bioplastics, which take over the roles of the plastics that we have already been using. So it is, really, just that switch over and going forward in a more sustainable way using these bioplastics.” 

Australian states and territories have been phasing out various plastics for several years. At the start of September 2024, more items have been banned in South Australia and Western Australia, including polystyrene containers and cups, plastic confetti, and plastic coffee cups and lids.

Chile, Kenya, India and New Zealand have also imposed restrictions on some single-use plastic products, such as bags or cutlery.

But there is a warning that the degradation of everyday plastic items, from packaging and in clothing, is creating microplastics that pollute the environment and pose a risk to health.    

Michelle Blewitt is the program director of the Australian Microplastic Assessment Project, a national citizen science organization, which has been monitoring microplastics.

She told the Australian Broadcasting Corp. the microplastic problem is getting worse.

“Micro plastics are particles that are less than 5mm in size and they can break up into smaller and smaller pieces until they become airborne.  So, they are found in our waterways and in the air and our homes and certainly on the beaches around our waterways as well.”

CSIRO scientists say the biodegradable plastic scheme is part of Australia’s commitment to the United Nations Global Treaty on plastic pollution.  It aims to be a legally binding international agreement between 175 countries to reduce the production and consumption of high-risk plastic.

About 98% of single-use plastic products are made from fossil fuels, according to the U.N.

LONDON — The growing mpox outbreaks in Africa that triggered the World Health Organization’s emergency declaration are largely the result of decades of neglect and the global community’s inability to stop sporadic epidemics among a population with little immunity against the smallpox-related disease, leading African scientists said Tuesday.

According to Dr. Dimie Ogoina, who chaired WHO’s mpox emergency committee, negligence has led to a new, more transmissible version of the virus emerging in countries with few resources to stop outbreaks.

Mpox, also known as monkeypox, had been spreading mostly undetected for years in Africa before the disease prompted the 2022 outbreak in more than 70 countries, Ogoina said at a virtual news conference.

“What we are witnessing in Africa now is different from the global outbreak in 2022,” he said. While that outbreak was overwhelmingly focused in gay and bisexual men, mpox in Africa is now being spread via sexual transmission as well as through close contact among children, pregnant women and other vulnerable groups.

And while most people over 50 were likely vaccinated against smallpox — which may provide some protection against mpox — that is not the case for Africa’s mostly young population, who Ogoina said were mostly susceptible.

Mpox belongs to the same family of viruses as smallpox but causes milder symptoms like fever and body aches. It mostly spreads through close skin-to-skin contact, including sex. People with more serious cases can develop prominent blisters on the face, hands, chest and genitals.

Earlier this month, WHO declared the surging mpox outbreaks in Congo and 11 other countries in Africa to be a global emergency.

On Tuesday, the Africa Centers for Disease Control and Prevention said there were more than 22,800 mpox cases and 622 deaths on the continent and that infections had jumped 200% in the last week. The majority of cases and deaths are in Congo, where most mpox infections are in children under 15.

Dr. Placide Mbala-Kingebeni, a Congolese scientist who helped identify the newest version of mpox, said diagnostic tests being used in the country did not always pick it up, making it hard to track the variant’s spread.

In May, Mbala-Kingebeni, who heads a lab at Congo’s National Institute for Biomedical Research, published research showing a new form of mpox that may be less deadly but more transmissible. The noted mutations suggested it was “more adapted to human transmission,” he said, but the lack of tests in Congo and elsewhere complicated efforts to monitor outbreaks.

The new variant has been detected in four other African countries as well as Sweden, where health officials said they have identified the first case of a person this month with the more infectious form of mpox. The person had been infected during a stay in Africa.

WHO said that available data to date does not suggest that the new form of mpox is more dangerous but that research is ongoing.

Marion Koopmans, a virologist at Erasmus Medical Centre in the Netherlands who has been studying mpox, said scientists were now seeing some significant impacts of the disease, noting that pregnant women were miscarrying or losing their fetuses and that some babies were being born infected with mpox.

Ogoina, a professor of infectious diseases at Niger Delta University in Nigeria, said that in the absence of vaccines and drugs, African health workers should focus on providing supportive care, like ensuring patients have enough to eat and are given mental health support, given the stigma that often comes with mpox.

“It’s very, very unfortunate that we have had mpox for 54 years and we are only now thinking about therapeutics,” he said.

Mbala-Kingebeni said strategies previously used to stop Ebola outbreaks in Africa might help, given the limited numbers of shots expected. He said authorities have estimated Africa needs about 10 million doses but might only receive about 500,000 — and it’s unclear when they might arrive.

“Finding a case and vaccinating around the case, like we did with Ebola, might help us target the hot spots,” he said.

Koopmans said that given the urgent need for vaccines in Africa, waiting for more doses to be produced was unrealistic.

“The short term really is about, who has vaccines and where are they to be best used next?” she said.

Spain’s health ministry announced Tuesday that it would dip into its mpox vaccine stockpile to donate 20% of its supply, about 500,000 doses, to African countries battling mpox.

“We consider it senseless to accumulate vaccines where they are not needed,” Spain’s health ministry said in a statement, adding Spain will recommend to the European Commission to propose that all member states also donate 20% of their vaccine stock.

Spain’s donation alone is more than what the European Union, vaccine Bavarian Nordic and the U.S. have pledged. Last week, Africa CDC said the EU and Bavarian Nordic had promised 215,000 mpox vaccines while the U.S. said it was donating 50,000 doses of the same vaccine to Congo. Japan has also donated some doses to Congo.

Meanwhile, the U.S. on Tuesday donated 10,000 doses of mpox vaccines to Nigeria where mpox has been common, making the vaccines the first to arrive in Africa since the global emergency was declared. The country has had a few dozen cases this year.

DEIR AL-BALAH, Gaza Strip — Palestinian health authorities and United Nations agencies on Sunday began a large-scale campaign of vaccinations against polio in the Gaza Strip, hoping to prevent an outbreak in the territory that has been ravaged by the ongoing Israel-Hamas war.

Authorities plan to vaccinate children in central Gaza until Wednesday before moving on to the more devastated northern and southern parts of the strip. The campaign began with a small number of vaccinations on Saturday and aims to reach about 640,000 children.

The World Health Organization said Thursday that Israel has agreed to limited pauses in the fighting to facilitate the campaign. There were initial reports of Israeli strikes in central Gaza early Sunday, but it was not immediately known if anyone was killed or wounded.

Hospitals in Deir al-Balah and Nuseirat confirmed that the campaign had begun early Sunday. Israel said Saturday that the vaccination program would continue through September 9 and last eight hours a day.

Gaza recently reported its first polio case in 25 years — a 10-month-old boy, now paralyzed in the leg. The World Health Organization says the presence of a paralysis case indicates there could be hundreds more who have been infected but aren’t showing symptoms.

Most people who have polio do not experience symptoms, and those who do usually recover in a week or so. But there is no cure, and when polio causes paralysis, it is usually permanent. If the paralysis affects breathing muscles, the disease can be fatal.

The vaccination campaign faces a host of challenges, from ongoing fighting to devastated roads and hospitals shut down by the war. Around 90% of Gaza’s population of 2.3 million people have been displaced within the besieged territory, with hundreds of thousands crammed into squalid tent camps.

Health officials have expressed alarm about disease outbreaks as uncollected garbage has piled up and the bombing of critical infrastructure has sent putrid water flowing through the streets. Widespread hunger has left people even more vulnerable to illness.

“We escaped death with our children, and fled from place to place for the sake of our children, and now we have these diseases,” said Wafaa Obaid, who brought her three children to the Al-Aqsa Martyrs Hospital in Deir al-Balah to get the vaccinations.

Ammar Ammar, a spokesperson for the U.N. children’s agency, said it hopes both parties adhere to a temporary truce in designated areas to enable families to reach health facilities.

“This is a first step,” he told The Associated Press. “But there is no alternative to a cease-fire because it’s not only polio that threatens children in Gaza, but also other factors, including malnutrition and the inhuman conditions they are living in.”

The vaccinations will be administered at roughly 160 sites across the territory, including medical centers and schools. Children under 10 will receive two drops of oral polio vaccine in two rounds, the second to be administered four weeks after the first.

Israel allowed around 1.3 million doses to be brought into the territory last month, which are now being held in refrigerated storage in a warehouse in Deir al-Balah. Another shipment of 400,000 doses is set to be delivered to Gaza soon.

The polio virus that triggered this latest outbreak is a mutated virus from an oral polio vaccine. The oral polio vaccine contains weakened live virus and in very rare cases, that virus is shed by those who are vaccinated and can evolve into a new form capable of starting new epidemics.

The war in Gaza began when Hamas-led militants stormed into Israel on October 7, killing some 1,200 people, mostly civilians, and abducting around 250 hostages. Around 100 remain in captivity, about a third of whom are believed to be dead.

Israel’s retaliatory offensive has killed over 40,000 Palestinians, according to the Gaza Health Ministry, which does not say whether those killed were fighters or civilians. The war has caused vast destruction across the territory, with entire neighborhoods wiped out and critical infrastructure heavily damaged.

The United States, Egypt and Qatar have spent months trying to broker a cease-fire and the release of the remaining hostages, but the talks have repeatedly stalled and a number of sticking points remain.

CHEYENNE, Wyoming — A “mega den” of hundreds of rattlesnakes in Colorado is getting even bigger now that late summer is here and babies are being born.

Thanks to livestream video, scientists studying the den on a craggy hillside in Colorado are learning more about these enigmatic — and often misunderstood — reptiles. They’re observing as the youngsters, called pups, slither over and between adult females on lichen-encrusted rocks.

The public can watch too on the Project RattleCam website and help with important work including how to tell the snakes apart. Since researchers put their remote camera online in May, several snakes have become known in a chat room and to scientists by names including “Woodstock,” “Thea” and “Agent 008.”

The live feed, which draws as many as 500 people at a time online, on Thursday showed a tangle of baby snakes with tiny nubs for rattles. They have a lot of growing to do: A rattlesnake adds a rattle segment each time it sheds its skin a couple times a year, on average.

The project is a collaboration between California Polytechnic State University in San Luis Obispo, snake removal company Central Coast Snake Services and Dickinson College in Carlisle, Pennsylvania.

By involving the public, the scientists hope to dispel the idea that rattlesnakes are usually fierce and dangerous. In fact, experts say they rarely bite unless threatened or provoked and often are just the opposite. 

Rattlesnakes are not only among the few reptiles that care for their young. They even care for the young of others. The adults protect and lend body heat to pups from birth until they enter hibernation in mid-autumn, said Max Roberts, a CalPoly graduate student researcher.

“We regularly see what we like to call ‘babysitting,’ pregnant females that we can visibly see have not given birth, yet are kind of guarding the newborn snakes,” Roberts said Wednesday.

As many as 2,000 rattlesnakes spend the winter at the location on private land, which the researchers are keeping secret to discourage trespassers. Once the weather warms, only pregnant females remain while the others disperse to nearby territory.

This year, the scientists keeping watch over the Colorado site have observed the rattlesnakes coil up and catch water to drink from the cups formed by their bodies. They’ve also seen how the snakes react to birds swooping in to try to grab a scaly meal.

The highlight of summer is in late August and early September when the rattlesnakes give birth over a roughly two-week period.

“As soon as they’re born, they know how to move into the sun or into the shade to regulate their body temperature,” Roberts said.

There are 36 species of rattlesnakes, most of which inhabit the U.S. They range across nearly all states and are especially common in the Southwest. Those being studied now are prairie rattlesnakes, which can be found in much of the central and western U.S. and into Canada and Mexico.

Like other pit viper species but unlike most snakes, rattlesnakes don’t lay eggs. Instead, they give birth to live young. Eight is an average-size brood, with the number depending on the snake’s size, according to Roberts.

Roberts is studying how temperature changes and ultraviolet sunlight affect snake behavior. Another graduate student, Owen Bachhuber, is studying the family and social relationships between rattlesnakes.

The researchers watch the live feed all day.

“We are interested in studying the natural behavior of rattlesnakes, free from human disturbance. What do rattlesnakes actually do when we’re not there?” Roberts said.

Now that the Rocky Mountain summer is cooling, some males have been returning. By November, the camera running on solar and battery power will be turned off until next spring, when the snakes will re-emerge from their “mega den.”

PATERZELL, Germany — How do you teach a bird how, and where, to fly?

The distinctive northern bald ibis, hunted essentially to extinction by the 17th century, was revived by breeding and rewilding efforts over the last two decades. But the birds — known for their distinctive black-and-iridescent green plumage, bald red head and long curved beak — don’t instinctively know which direction to fly to migrate without the guidance of wild-born elders. So a team of scientists and conservationists stepped in as foster parents and flight instructors.

“We have to teach them the migration route,” said biologist Johannes Fritz.

The northern bald ibis once soared over North Africa, the Arabian Peninsula and much of Europe, including southern Germany’s Bavaria. The migratory birds were also considered a delicacy, and the bird, known as the Waldrapp in German, disappeared from Europe, though a few colonies elsewhere survived.

The efforts of Fritz and the Waldrappteam, a conservation and research group based in Austria, brought the Central European population from zero to almost 300 since the start of their project in 2002.

The feat moved the species from a “critically endangered” classification to “endangered” and, Fritz says, is the first attempt to reintroduce a continentally extinct migratory bird species.

But while northern bald ibises still display the natural urge to migrate, they don’t know which direction to fly without the guidance of wild-born elders. The Waldrappteam’s early reintroduction attempts were largely unsuccessful because, without teaching the birds the migration route, most disappeared soon after release. Instead of returning to suitable wintering grounds such as Tuscany, Italy, they flew in different directions and ultimately died.

So the Waldrappteam stepped in as foster parents and flight instructors for the Central European population, which was made up of descendants from multiple zoo colonies and released into the wild in the hopes of creating a migratory group. This year marks the 17th journey with human-led migration guides, and the second time they’ve been forced to pilot a new route to Spain due to climate change.

To prepare them for travel, the chicks are removed from their breeding colonies when they are just a few days old. They are taken to an aviary that’s overseen by the foster parents in the hopes of “imprinting” — when the birds will bond with those humans to ultimately trust them along the migration route.

Barbara Steininger, a Waldrapp team foster mother, said she acts like “their bird mom.”

“We feed them, we clean them, we clean their nests. We take good care of them and see that they are healthy birds,” she said. “But also we interact with them.”

Steininger and the other foster parents sit on the back of a microlight aircraft, waving and shouting encouragement through a bullhorn as it flies through the air.

It’s a bizarre scene: The aircraft looks like a flying go-kart with a giant fan on the back and a yellow parachute keeping it aloft. Still, three dozen birds follow the contraption, piloted by Fritz, as it sails over alpine meadows and foothills.

Fritz was inspired by “Father Goose” Bill Lishman, a naturalist who taught Canadian geese to fly alongside his ultra-light plane beginning in 1988. He later guided endangered whooping cranes through safe routes and founded the nonprofit “Operation Migration.” Lishman’s work prompted the 1996 movie “Fly Away Home” but features a young girl as the geese’s “mother.”

Like Lishman, Fritz and his team’s efforts have worked. The first bird independently migrated back to Bavaria in 2011 from Tuscany. More have flown the route that’s upward of 550 kilometers (342 miles) each year, and the team hopes the Central European population will be more than 350 birds by 2028 and become self-sustaining.

But the effects of climate change mean the Waldrapp are migrating later in the season now, which forces them to cross the Alps in colder, more dangerous weather — without the aid of warm currents of air, known as thermals, that rise upward and help the birds soar without expending extra energy.

In response, the Waldrappteam piloted a new route in 2023, from Bavaria to Andalusia in southern Spain.

This year, the route is roughly 2,800 kilometers (1,740 miles) — some 300 kilometers (186 miles) longer than last year’s path. Earlier this month from an airfield in Paterzell, in upper Bavaria, the team guided 36 birds along one stage through bright blue skies and a tailwind that increased their speed.

The entire journey to Spain could take up to 50 days and end in early October. But Fritz says the effort is bigger than just the northern bald ibises: It’s about paving the way for other threatened migratory species to fly.

MANILA, Philippines — A Vietnamese doctor who has helped seek justice for victims of the powerful defoliant dioxin “Agent Orange” used by U.S. forces during the Vietnam War is among this year’s winners of the Ramon Magsaysay Awards — regarded as Asia’s version of the Nobel Prizes. 

Other winners announced on Saturday were a group of doctors who struggled to secure adequate health care for Thailand’s rural poor, an Indonesian environmental defender, a Japanese animator who tackles complex issues for children, and a Bhutanese academician promoting his country’s cultural heritage to help current predicaments. 

First given in 1958, the annual awards are named after a Philippine president who died in a 1957 plane crash, and honor “greatness of spirit” in selfless service to people across Asia. 

“The award has celebrated those who challenge the status quo with integrity by courageously confronting systemic injustices, transform critical sectors through groundbreaking solutions that drive societal progress, and address pressing global issues with unwavering resilience,” said Susanna B. Afan, president of the award foundation. 

Vietnamese doctor Nguyen Thi Ngoc Phuong carried out extensive research into the devastating and long-term effects of Agent Orange. She said she first encountered it in the late 1960s as a medical intern when she helped deliver babies with severe birth defects as a result of the lingering effect of highly toxic chemical, according to the awards body. 

“Her work serves as a dire warning for the world to avoid war at all costs as its tragic repercussions can reach far into the future,” the Magsaysay foundation said. “She offers proof that it can never be too late to right the wrongs of war and gain justice and relief for its hapless victims.” 

American forces used Agent Orange during the Vietnam War to defoliate Vietnamese jungles and destroy crops for the Vietnamese Communists, or Viet Cong, who fought against South Vietnam and the United States. 

Between 1962 and 1971, the U.S. military sprayed roughly 11 million gallons of the chemical agent dioxin used in Agent Orange across large swaths of southern Vietnam. Dioxin stays in the soil and in the sediment of lakes and rivers for generations. It can enter the food supply through the fat of fish and other animals. 

Vietnam says as many as 4 million citizens were exposed to the herbicide and as many as 3 million have suffered illnesses from it, including the children of people exposed during the war. 

Indonesian Farwiza Farhan won the award for helping lead a group to protect the Leuser Ecosystem, a 2.6-million-hectare forest on Sumatra Island in his country’s Aceh province where some of the world’s most highly endangered species have managed to survive, the foundation said. 

Her group helped win a court verdict that led to $26 million in fines against a palm oil company that burned forests and stopped a hydroelectric dam that would have threatened the elephant’s habitat, the foundation said. 

Miyazaki Hayao, a popular animator in Japan, was cited by the awards body as a co-founder in 1985 of Studio Ghibli, a leading proponent of animated films for children. Three Ghibli productions were among Japan’s 10 top-grossing films. 

“He tackles complicated issues, using his art to make them comprehensible to children, whether it be about protecting the environment, advocating for peace or championing the rights and roles of women in society,” the foundation said. 

The Rural Doctors Movement, a group of Thai physicians, won the award for their “decades of struggle … to secure adequate and affordable health care for their people, especially the rural poor,” the foundation said. 

“By championing the rural poor, the movement made sure to leave no one behind as the nation marches forward to greater economic prosperity and modernization,” it said. 

Karma Phuntsho from Bhutan, a former Buddhist monk and an Oxford-educated scholar, was cited by the awards body for his academic works in the field of Buddhism and Bhutan’s rich history and cultural heritage that were being harnessed to address current and future problems in his country, including unemployment and access to high-quality education. 

The winners will be presented with their awards and a cash prize on November 16 at the Metropolitan Theater in Manila.

ABUJA, Nigeria — Weeks of flooding have killed 185 people in Nigeria and washed away homes and farmlands, the country’s disaster management agency said, further threatening food supplies, especially in the hard-hit northern region.

The floods, blamed on poor infrastructure and badly maintained dams, have displaced 208,000 people in 28 of Nigeria’s 36 states, the National Emergency Management Agency said in an update Friday, triggering frantic efforts to evacuate hundreds of thousands to makeshift shelters.

Nigeria records flooding every year mostly as a result of failure to follow environmental guidelines and inadequate infrastructure. The worst floods the country has seen in a decade were in 2022, when more than 600 people were killed and more than 1 million people were displaced.

However, unlike in 2022 when the floods were blamed on heavier rainfall, the Nigerian Meteorological Agency predicted delayed or normal rains in most parts of the country this year and said the current floods were more a result of human activities.

“What we are doing is causing this climate change, so there is a shift from the normal,” said Ibrahim Wasiu Adeniyi, head of the central forecasting unit. “We have some who dump refuse indiscriminately, some build houses without approvals along the waterways.”

The Nigerian disaster response agency warned the flooding could get worse in the coming weeks as the flood waters flow downwards to the central and southern states.

“People [in flood-prone areas] need to evacuate now … because we don’t have time any longer,” said its spokesperson, Manzo Ezekiel.

In Jigawa, the worst-hit state, has recorded 37 deaths. The impact of the floods there has been “devastating,” and authorities are converting public buildings and schools as shelters for those displaced, according to Nura Abdullahi, head of emergency services in the state.

The floods have so far destroyed 107,000 hectares of farmland, especially in northern states, among the most affected and where most of Nigeria’s harvests come from.

Many farmers in the region are already unable to farm as much as they would like either because of decreasing inputs as families struggle amid Nigeria’s economic hardship or as a result of violent attacks that have forced them to flee.

Nigeria has the highest number of hungry people in the world, with 32 million — 10% of the global burden — facing acute hunger in the country, according to the U.N. food agency.

Resident Abdullahi Gummi in Zamfara state’s Gummi council area said the floods destroyed his family’s farmlands, which are their source of income. “We spent around 300,000 naira [$188] on planting, but everything is gone,” Gummi said.

LONDON — Polio was eliminated from most parts of the world as part of a decadeslong effort by the World Health Organization and partners to wipe out the disease. But polio is one of the world’s most infectious diseases and is still spreading in a small number of countries. The WHO and its partners want to eradicate polio in the next few years.

Until it is gone from the planet, the virus will continue to trigger outbreaks anywhere children are not fully vaccinated. The recent polio infection in an unvaccinated baby in Gaza is the first time the disease has been reported in the territory in more than 25 years.

What is polio?

Polio is an infection caused by a virus that mostly affects children younger than 5. Most people infected with polio don’t have any symptoms, but it can cause fever, headaches, vomiting and stiffness of the spine. In severe cases, polio can invade the nervous system and cause paralysis within hours, according to the WHO. The U.N. agency estimates that 1 in 200 polio cases results in permanent paralysis, usually of the legs. Among children who are paralyzed, up to 10% die when their breathing muscles are paralyzed.

The virus spreads from person to person, entering the body though the mouth. It is most often spread by contact with waste from an infected person or, less frequently, through contaminated water or food.

Just how bad was polio in the past?

Very bad. Polio has existed for centuries; ancient Egyptian hieroglyphics show children walking with canes, with the wasted limbs characteristic of polio victims.

Before the first vaccine was developed in the 1950s, polio was among the most feared diseases. An explosive 1916 outbreak in New York killed more than 2,000 people, and the worst recorded U.S. outbreak in 1952 killed more than 3,000. Many people who survived polio suffered lifelong consequences, including paralysis and deformed limbs. Some people whose breathing muscles were paralyzed required “iron lung” chambers to help them breathe.

When did the eradication campaign begin?

WHO passed a resolution to eradicate polio in 1988, spurred on by the success of eliminating smallpox eight years earlier. Their original target was to wipe out polio by 2000. The WHO — along with partners including the U.S. Centers for Disease Control and Prevention, UNICEF and Rotary International — boosted the production of an oral vaccine and rolled out widespread immunization campaigns. Polio cases dropped by more than 99%.

Afghanistan and Pakistan are the only countries where the spread of polio has never been stopped. There are also outbreaks in more than a dozen other countries, mostly in Africa. WHO and partners now aim to wipe out polio by 2026.

Why has it taken so long?

It’s extraordinarily difficult. Stopping polio outbreaks means vaccinating at least 95% of the population everywhere, including in conflict-ridden countries and poor regions with broken health systems and other priorities.

The oral vaccine is cheap, easy to use and is better at preventing entire populations from becoming infected. But it contains weakened, live polio virus and in very rare cases can spread and cause polio in unvaccinated people. In even rarer instances, the live virus from the vaccine can mutate into a new form capable of starting new outbreaks.

Health authorities have become more successful in reducing the number of cases caused by the wild polio virus. Vaccine-related cases now cause the majority of infections worldwide.

“The problem with trying to eradicate polio is that the need for perfection is so great and there are so many weak links,” said Scott Barrett, a Columbia University professor who has studied polio eradication. “The technical feasibility is there, but we live in a vastly imperfect world.”

geneva — The head of the World Health Organization believes mpox outbreaks in Africa might be stopped in the next six months, and he said Friday that the agency’s first shipment of vaccines should arrive in Congo within days. 

To date, Africa has received a small fraction of the vaccines needed to slow the spread of the virus, especially in Congo, which has the most cases — more than 18,000 suspected cases and 629 deaths. 

“With the governments’ leadership and close cooperation between partners, we believe we can stop these outbreaks in the next six months,” WHO Director-General Tedros Adhanom Ghebreyesus said at a press briefing. 

He said that while mpox infections have been rising quickly in the last few weeks, there have been relatively few deaths. Tedros also noted there were 258 cases of the newest version of mpox, with patients identified in Burundi, Rwanda, Kenya, Uganda, Sweden and Thailand. 

Earlier this month, WHO declared the mpox outbreaks in Africa a global emergency, hoping to spur a robust global response to the disease on a continent where cases were spreading largely unnoticed for years, including in Nigeria. In May, scientists detected a new version of the disease in Congo that they think could be spreading more easily. 

Mpox, formerly called monkeypox, is related to smallpox but typically causes milder symptoms, including fever, headache and body aches. In severe cases, people can develop painful sores and blisters on the face, chest, hands and genitals. Mpox is typically spread via close skin-to-skin contact. 

WHO estimated about 230,000 vaccines could be sent “imminently” to Congo and elsewhere. The agency said it was also working on education campaigns to raise awareness of how people could avoid spreading mpox in countries with outbreaks. 

Maria Van Kerkhove, who directs WHO’s epidemic and pandemic diseases department, said the agency was working to expedite vaccine access for affected countries — given the limited supply available. 

Scientists have previously pointed out that without a better understanding of how mpox is spreading in Africa, it may be difficult to know how best to use the shots. 

Earlier this week, the head of Africa’s Centers for Disease Control and Prevention said the continent was hoping to receive about 380,000 doses of mpox vaccines promised by donors, including the U.S. and the European Union. That’s less than 15% of the doses authorities have said are needed to end the mpox outbreaks in Congo.
