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.

Afghan health officials visit Indian medical institute to expand ties
India has historically been a key partner in Afghanistan’s health and education sectors, providing training, medical support and institutional cooperation.
During an official visit to India, a technical delegation from Afghanistan’s Ministry of Public Health visited the Hamdard Institute of Medical Sciences and Research (HIMSR) in New Delhi, as part of efforts to strengthen cooperation in the health sector, particularly in the field of traditional medicine.
Officials and senior professors at HIMSR welcomed the Afghan team and provided detailed briefings on the institution’s academic programmes, research activities and medical services.
Discussions focused on opportunities for closer collaboration in traditional and integrative medicine, an area where Hamdard has long-standing expertise and international recognition.
HIMSR’s leadership expressed readiness to work with Afghan health authorities on joint research initiatives, quality testing and standardisation of traditional medicines through Hamdard’s laboratories, as well as knowledge-sharing programmes. The institution also pledged to offer scholarships and specialised training opportunities for Afghan doctors and medical professionals.
The visit comes as Afghanistan seeks to rebuild and strengthen its public health system amid ongoing economic and humanitarian challenges, with an emphasis on cost-effective and culturally accepted healthcare approaches such as traditional medicine.
India has historically been a key partner in Afghanistan’s health and education sectors, providing training, medical support and institutional cooperation.
Both sides said enhanced collaboration would contribute to improving public health outcomes, standardising traditional medicine practices, and expanding scientific and medical institutions in Afghanistan.
They reaffirmed their commitment to developing the partnership in a sustainable manner, aimed at long-term capacity building and mutual benefit.

Amid strained Pakistan ties, Afghanistan turns to India for health cooperation
Afghanistan’s Minister of Public Health, Noor Jalal Jalali, has said that Afghanistan is looking to strengthen health-sector cooperation with India, as relations with Pakistan have cooled and the country seeks alternative partners to meet its medical needs.
Speaking during his visit to India, Jalali said his primary focus is combating disease and improving public health, stressing that he is ready to seek assistance and cooperation from any country willing to help Afghanistan in this regard.
“My enemy is disease,” Jalali told reporters. “I will shoot at it from anywhere it is possible.”
He said the purpose of his visit is to open a new chapter of cooperation between Afghanistan and India.
Jalali noted that a significant portion of Afghanistan’s medicine requirements had previously been met by Pakistan. However, amid strained relations with Islamabad, the Islamic Emirate is now exploring alternative options to ensure the steady supply of essential medicines. He added that India could serve as a key partner.

India issues over 200 medical visas to Afghans in last four months
Since the launch of the new Afghan visa module in April 2025, more than 500 visas, including over 200 medical visas, have been issued in the last four months, Indian media reported citing a senior Health Ministry official on Thursday.
India has also approved and implemented several key healthcare infrastructure projects in Afghanistan, including the construction of five maternity and health clinics in the provinces of Paktia, Khost and Paktika, a 30-bed hospital in Kabul, and the construction or upgradation of major facilities such as an Oncology Centre, Trauma Centre, Diagnostic Centre and Thalassemia Centre in Kabul, The Hindu newspaper reported. Additional proposals for health sector support are currently under active consideration.
On Thursday, India reaffirmed its continued commitment to supporting Afghanistan’s health sector and humanitarian needs during a meeting held between Union Minister for Health and Family Welfare J.P. Nadda and Afghanistan’s Minister of Public Health Noor Jalal Jalali.
During the meeting, both sides reviewed ongoing health cooperation and discussed avenues to further strengthen collaboration in healthcare infrastructure, medical supplies and capacity building.
The Union Minister underlined that guided by India’s long-standing people-centric approach, Prime Minister Narendra Modi has always emphasised that India’s engagement with Afghanistan should remain focused on welfare, capacity building and access to critical healthcare services.
Nadda added that India’s assistance to Afghanistan remains guided by humanitarian considerations and the long-standing bonds between the peoples of the two countries.
“India has supplied 327 tonnes of medicines and vaccines to Afghanistan over the past four years. Cancer medicines and one CT scan machine, as requested by the Afghan Ministry of Public Health, are ready for dispatch and will be delivered by the end of this month. Proposals from the Afghan side for a radiotherapy machine and additional medical supplies are also being processed,” he said.
The meeting also discussed capacity-building initiatives. India is working on modalities to send a team of senior Indian doctors to Afghanistan to organise a medical camp and provide training to Afghan doctors.
“At the meeting, India has reiterated its commitment to providing free treatment in India to Afghan patients suffering from emergency and serious ailments, and to facilitating medical visas,” said an Indian Health Ministry official.
