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.

Afghanistan, Uzbekistan move to expand cooperation in pharmaceutical sector
The two sides discussed expanding cooperation in the production and regulation of medicines and health products.
Afghanistan’s Ministry of Public Health has announced that Abdul Basir Qane, Director General of Drug and Health Products Regulation at the ministry’s Food and Drug Deputy, held talks with Uzbek health officials during his visit to Uzbekistan to strengthen bilateral cooperation in the pharmaceutical sector.
According to a statement issued by the ministry, Qane and his technical delegation met with Abdullah Azizov, head of Uzbekistan’s regulatory authority for medical and pharmaceutical industries, along with other senior officials.
The two sides discussed expanding cooperation in the production and regulation of medicines and health products, facilitating the entry of Uzbek pharmaceutical manufacturers into the Afghan market, implementing inspections in line with Good Manufacturing Practice (GMP) standards, streamlining the registration process for medicines, and increasing bilateral trade in pharmaceutical products.
The discussions also covered the development of laboratory infrastructure, capacity building and training for specialists, the exchange of expertise in regulatory and inspection fields, and broader technical and professional cooperation between the two countries.
At the conclusion of the meeting, both sides reaffirmed their commitment to strengthening long-term cooperation in the pharmaceutical and health products sector, supporting the activities of pharmaceutical companies in both markets, and continuing dialogue on mutually beneficial joint projects, the ministry said.

Polio cases in Afghanistan rise to six in 2026 as two new cases confirmed
According to the WHO, one of the newly confirmed cases was identified in Nari district of Kunar province, while the other was reported in Nahr-e-Siraj district of Helmand province.
The World Health Organization (WHO) has announced that the number of confirmed polio cases in Afghanistan has risen to six in 2026, following the detection of two new infections in the country.
According to the WHO, one of the newly confirmed cases was identified in Nari district of Kunar province, while the other was reported in Nahr-e-Siraj district of Helmand province. The organization also stated that 34 positive environmental samples of wild poliovirus have been recorded in Afghanistan so far this year.
The report adds that in 2025, a total of 52 wild poliovirus type 1 cases were confirmed across Afghanistan and Pakistan, including 21 cases in Afghanistan and 31 in Pakistan.
WHO further noted that in 2026 so far, nine wild poliovirus type 1 cases have been reported across both countries, with six in Afghanistan and three in Pakistan.
Health experts say that low public awareness, resistance from some families to vaccination campaigns, and limited access to remote areas remain key factors behind the continued spread of the disease.
They emphasize that polio is incurable and vaccination is the only effective way to prevent infection.
Public health specialists also stress the need to expand immunization coverage, particularly in hard-to-reach areas, and to strengthen public awareness campaigns, warning that eradication efforts will remain difficult without broad community cooperation.
Afghanistan and Pakistan remain the only two countries in the world where wild poliovirus is still endemic and has not been fully eradicated.

Health ministry urges greater public participation in blood donation
The appeal was made on Saturday as health officials marked World Blood Donor Day, an annual event aimed at raising awareness about the importance of voluntary blood donation and recognizing the contribution of donors in saving lives.
Afghanistan’s Ministry of Public Health has called on citizens to increase their participation in blood donation campaigns, warning that many patients still struggle to obtain compatible blood in emergencies despite improvements in the country’s blood management system.
The appeal was made on Saturday as health officials marked World Blood Donor Day, an annual event aimed at raising awareness about the importance of voluntary blood donation and recognizing the contribution of donors in saving lives.
Speaking at the ceremony, officials highlighted the critical role blood donors play in supporting the healthcare system and ensuring that hospitals have adequate supplies for patients requiring urgent treatment.
Abdul Wali Haqqani, Deputy Minister for Health Services at the Ministry of Public Health, said that shortages in blood reserves continue to pose challenges for healthcare providers, particularly when patients require specific blood types.
“Unfortunately, patients who need blood do not always have immediate access to compatible negative blood groups,” Haqqani said. “Blood donation is a simple yet invaluable humanitarian act. The World Health Organization recommends that at least one percent of a country’s population donate blood regularly to maintain sufficient reserves.”
Haqqani stressed that increasing public participation in blood donation could significantly improve the availability of life-saving blood supplies and strengthen healthcare services across the country.
Meanwhile, Wahdat Alkozi, Director of Curative Medicine at the ministry, said Afghanistan has made notable progress in blood management in recent years. He noted that standardized blood separation and storage systems are now operating at the Central Blood Bank and several regional hospitals.
“We are working to expand these systems throughout the country so that patients can have greater access to safe and standardized blood services,” Alkozi said.
According to officials from the Central Blood Bank, more than 220,000 units of blood were collected from voluntary donors over the past year. The blood was used in the treatment of more than 250,000 patients nationwide, underscoring the growing demand for blood supplies in hospitals and healthcare facilities.
However, Niazgul Niazmand, head of the Central Blood Bank, said the shortage of negative blood groups remains a major challenge due to the limited number of donors with those blood types.
Health experts emphasize that blood donation not only helps save the lives of accident victims, surgical patients, mothers experiencing childbirth complications, and individuals suffering from serious illnesses, but can also benefit donors by promoting healthy blood circulation and stimulating the production of new blood cells.
World Blood Donor Day is observed every year on June 14 to encourage voluntary blood donation and raise awareness about the ongoing need for safe blood and blood products around the world.
