Experts warn bird flu virus changing rapidly in largest ever outbreak

The virus causing record cases of avian influenza in birds across the world is changing rapidly, experts have warned, as calls increase for countries to vaccinate their poultry.
While emphasizing that the risk to humans remains low, the experts who spoke to AFP said that the surging number of bird flu cases in mammals was a cause for concern.
Since first emerging in 1996, the H5N1 avian influenza virus had previously been confined to mostly seasonal outbreaks.
But “something happened” in mid-2021 that made the group of viruses much more infectious, according to Richard Webby, the head of a World Health Organization collaborating center studying influenza in animals.
Since then, outbreaks have lasted all year round, spreading to new areas and leading to mass deaths among wild birds and tens of millions of poultry being culled, AFP reported.
Webby, who is a researcher at St Jude Children’s Research Hospital in the US city of Memphis, told AFP it was “absolutely” the largest outbreak of avian influenza the world had seen.
He led research, published this week in the journal Nature Communications, showing how the virus rapidly evolved as it spread from Europe into North America.
The study said the virus increased in virulence, which means it causes more dangerous disease, when it arrived in North America.
The researchers also infected a ferret with one of the new strains of bird flu.
They found an unexpectedly “huge” amount of the virus in its brain, Webby said, indicating it had caused more serious disease than previous strains.
Emphasizing that the risk in humans was still low, he said that “this virus is not being static, it’s changing”.
“That does increase the potential that even just by chance” the virus could “pick up genetic traits that allow it to be more of a human virus,” he said.
In rare cases, humans have contracted the sometimes deadly virus, usually after coming in close contact with infected birds.
The virus has also been detected in a soaring number of mammals, which Webby described as a “really, really troubling sign”.
Last week Chile said that nearly 9,000 sea lions, penguins, otters, porpoises and dolphins have died from bird flu along its north coast since the start of the year, AFP reported.
Most mammals are believed to have contracted the virus by eating an infected bird.
But Webby said that what “scares us the most” are indications from a Spanish mink farm, or among sea lions off South America, that the virus could be transmitting between mammals.
Ian Brown, virology head at the UK’s Animal and Plant Health Agency, said there has not yet been “clear evidence that this virus is easily sustaining in mammals.”
While the virus is changing to become “more efficient and more effective in birds,” it remains “unadapted to humans,” Brown told AFP.
Avian viruses bind to different receptors on the host cell than human viruses, Webby said.
It would take “two or three minor changes in one protein of the viruses” to become more adapted to humans, he said.
“That is what we’re really looking out for.”
Vaccinating poultry
One way to bring down the number of total bird flu cases, and therefore reduce the risk to humans, would be for countries to vaccinate their poultry, Webby said.
A few nations including China, Egypt and Vietnam have already held vaccination campaigns for poultry.
But many other countries have been reluctant due to import restrictions in some areas, and fears vaccinated birds that nonetheless get infected could slip through the net.
In April, the United States started testing several vaccine candidates for potential use on birds.
France recently said it hopes to start vaccinating poultry as early as autumn this year.
Christine Middlemiss, the UK’s chief veterinary officer, said that vaccinating poultry was not “a silver bullet because the virus changes constantly”.
But traditionally reluctant countries should consider vaccinating poultry more often, Middlemiss told AFP at an event at the UK’s embassy in Paris last week.
World Organisation for Animal Health director general Monique Eloit said that the issue of vaccinating poultry should be “on the table”.
After all, “everyone now knows that a pandemic is not just a fantasy — it could be a reality,” she added.

Health services to be expanded urgently for return refugees at Torkham border
Since 1 April at least 44,900 people have returned, with around 58% of them children, according to the UN Refugee Agency (UNHCR).

Afghanistan’s health ministry said Tuesday it is expanding health services at Torkham in Nangarhar to cope with the growing number of returning refugees from Pakistan.
According to a statement issued by the ministry, a coordination meeting was recently held to discuss the expansion of health services.
The meeting was chaired by Mawlawi Aminullah Sharif, Director of Public Health in Nangarhar Province, and attended by representatives from various organizations including the World Health Organization (WHO), UNICEF, and other partners.
The meeting focused on improving emergency preparedness and response, enhancing healthcare support for returnees, and addressing current operational challenges, the statement read.
Officials emphasized the urgent need to strengthen health service delivery in response to the growing number of returning citizens.
As a key outcome, participants agreed to increase the number of health facilities and medical staff at the border. This decision aims to ensure timely access to medical care for all returnees and to better manage the health-related pressures caused by the ongoing influx.
Tens of thousands of Afghans are facing dire conditions in makeshift camps after crossing the border from Pakistan, an Islamic Relief assessment team reported on Monday.
“Many are arriving in Afghanistan without any shelter, food, cash or water, and families told us they had to leave all their possessions – including animals and household utensils – behind as they cannot afford to bring them,” Islamic Relief said in the report.
Ramin Sadat from Islamic Relief was part of an assessment team at the Torkham border crossing in eastern Afghanistan. He said this new wave of returning refugees “is unlike anything I’ve seen before. People arrive in droves, covered in dust, crammed onto trucks, and facing a barren border with no basic services in sight. The first thing that greets them is a harsh, windy storm swirling with dust.”
Tens of thousands of families are expected to arrive in the coming days and months, in the wake of the Pakistan government’s announcement that all undocumented individuals and holders of Afghan Citizen Cards (ACC) must leave the country by 31 March 2025 or face deportation.
Since 1 April at least 44,900 people have returned, with around 58% of them children, according to the UN Refugee Agency (UNHCR).

Aid cuts could leave more women dying in pregnancy and birth, UN says
The cuts have had “pandemic-like effects” on health systems globally and could have a “more structural, deep-seated effect”, says WHO director

Cuts to aid budgets are threatening to undermine years of progress in reducing the number of women dying during pregnancy and childbirth, and could lead to a rise in deaths, the United Nations has warned.
Globally, there was a 40% decline in maternal deaths between 2000 and 2023, a report by UN agencies including the World Health Organization (WHO) showed on Monday, largely due to better access to essential health services.
That could now go into reverse, the WHO said in a statement accompanying the report which did not mention specific cuts but came in the wake of a foreign aid freeze by the U.S. government and the ending of funding through the United States Agency for International Development (USAID) for many programmes.
Other donor countries including Britain have also announced plans to cut aid budgets.
“One of the headline messages is that the funding cuts risk not only that progress, but we could have a shift backward,” said Dr Bruce Aylward, Assistant Director-General, Universal Health Coverage at the WHO.
The cuts have had “pandemic-like effects” on health systems globally and could have a “more structural, deep-seated effect,” Aylward added.
The WHO said the cuts were already rolling back vital services for maternal, newborn and child health in many countries, reducing staff numbers, closing facilities and disrupting supply chains for supplies including treatments for hemorrhage and pre-eclampsia.
Cuts to other areas, such as malaria and HIV treatment, would also impact maternal survival, the UN said.
Even before the aid cuts led by the United States, things were backsliding in some countries, and progress has slowed globally since 2016, the report said.
In 2023, despite recent progress, a woman still died roughly every two minutes – around 260,000 in total that year – from complications that were mainly preventable and treatable, it added.
The situation was particularly bad in countries affected by conflict or natural disaster, although the U.S. itself is one of only four countries to have seen its maternal mortality rate increase significantly since 2000, alongside Venezuela, the Dominican Republic and Jamaica.
The COVID-19 pandemic also had an impact, the report said: 40,000 more women died due to pregnancy or childbirth in 2021, bringing the total number of deaths that year to 322,000.
“While this report shows glimmers of hope, the data also highlights how dangerous pregnancy still is in much of the world today – despite the fact that solutions exist,” WHO Director-General Tedros Adhanom Ghebreyesus said.

Global organizations warn of health crisis due to aid cuts in Afghanistan

Global organizations are raising alarms about the impact of aid cuts on Afghanistan’s health sector and the reduction in funding for humanitarian organizations operating in the country.
UN-affiliated bodies have stated that the complete suspension of aid from the United States and the reduction of the 2025 budget could lead to the closure or suspension of nearly 2,000 healthcare centers across Afghanistan.
The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) has further warned that if only 25 percent of the required funding is provided, 7 million out of the 9.3 million people in need of medical services will be left without access to healthcare.
The report highlights that without immediate and sufficient funding, child mortality rates could rise sharply, as malnutrition remains one of the leading causes of death for children under the age of five.
The World Food Programme (WFP) has also warned that Afghanistan is facing a severe malnutrition crisis among children, with the number of malnourished children expected to reach 3.5 million by 2025.
Recent reports from the WFP reveal that 8 out of 10 families in Afghanistan are unable to afford a sufficient diet, and 3 out of 4 families are being forced to borrow money to purchase basic food items.
UN agencies have stressed the urgent need for the international community to address the humanitarian crisis in Afghanistan and provide the necessary aid.
This comes after Afghanistan’s Ministry of Economy dismissed reports from some international organizations about the growing poverty in the country, labeling them as exaggerated and far from reality.
