Experts warn bird flu virus changing rapidly in largest ever outbreak

Published

on

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.

Herat Regional Hospital struggling to deal with heavy patient load

Published

on

Herat Regional Hospital has a capacity to treat about 1,000 patients a day, 650 as in-patients. However, the hospital is being stretched to its limits and is treating more than double this number of people every day, hospital officials say.

Officials say that in most wards, there are two patients per bed. They say the hospital needs to expand - that they urgently need more space and more equipment.

According to doctors, the High Care Unit has only 10 beds, when it actually needs at least 65. In addition, they say the dialysis department is only running at half-mast. It has 17 dialysis machines, but only eight are in working order.

Herat residents have also raised concern over the state of the hospital and said some departments, especially the dialysis unit and pediatrics urgently need equipment and additional space.

Afghanistan is grappling with significant health challenges marked by a fragile healthcare system and unequal access to services, particularly in rural areas.

This is due to a number of issues such as transportation difficulties, shortage of healthcare professionals, and limited access to quality healthcare services.

Despite efforts to improve the country’s healthcare infrastructure, Afghanistan continues to grapple with systemic issues that hinder effective healthcare delivery. Analysis by UN agencies of under-served areas shows that 13.2 million people in 34 provinces reside in areas where primary healthcare services are not accessible within a one-hour walking distance.

Excluding Afghan women from medical institutes threatens the future of health care in the country: MSF

Published

on

The Islamic Emirate of Afghanistan’s (IEA) decision to bar women from studying in medical institutes will have far-reaching consequences for women’s health in the country, Médecins Sans Frontières (Doctors Without Borders) said on Friday.

This is another stage in the removal of women from public and professional life in Afghanistan. Already, there is an insufficient number of female health care workers in the country, impacting the availability of health care, especially given the separation of hospital wards by gender. New constraints will further restrict access to quality health care and pose serious dangers to its availability in the future, MSF said in a statement.

“There is no health care system without educated female health practitioners,” said Mickael Le Paih, MSF’s country representative in Afghanistan. “At MSF, more than 50 percent of our medical staff are women. The decision to bar women from studying at medical institutes will further exclude them from both education and the impartial provision of health care.”

The medical needs in Afghanistan are huge, and more female Afghan medical staff need to be trained to address them. For this to happen, women need to have access to education. Education restrictions for women and girls put in place in 2024, 2022, and 2021 considerably reduce the number of female medical staff in the future, MSF said.

“If no girls can attend secondary school, and no women can attend university or medical institutes, where will the female health professionals of the future come from and who will attend to Afghan women when they are at their most vulnerable?” said Le Paih. “For essential services to be available to all genders, they must be delivered by all genders.”

Recently, there have been reports that the leader of the Islamic Emirate has ordered the closure of medical institutes to women. The Islamic Emirate has not yet officially commented on this matter.

Afghanistan’s Acting Minister of Public Health has held in depth discussions on managing diseases such as malaria, tuberculosis, and polio with China’s Deputy Director for Disease Control and Prevention, Shen Hongbing. 

On an official visit to China, Mawlawi Noor Jalal Jalali also discussed other issues, with Shen and other officials, such as monitoring of diseases, disaster management processes and capacity building for Afghan healthcare workers.

Jalali, who was in China for the World Conference on Traditional Medicine 2024, also toured China’s Disease Control and Prevention Center (CDC) and its National Influenza Center.

The conference, which was held on Tuesday and Wednesday in Beijing, was jointly held by the World Health Organization (WHO) and Chinese sponsors, including China’s National Health Commission.

The opening ceremony of the two-day event was attended by health officials of governments and international organizations, experts and scholars, and deputies from medical institutions. 

WHO Director-General Tedros Adhanom Ghebreyesus gave a speech via video.

Addressing delegates at the conference, the ministry cited Jalali as having said that traditional medicine in Afghanistan needs to be regulated and integrated into modern healthcare practices.

He also advocated for strengthened bilateral cooperation between China and Afghanistan to enhance capacity building, experience sharing, and joint research in the sector.

Afghanistan’s health ministry has meanwhile established a Traditional Medicine Department which is currently tasked with formulating policies and guidelines to regulate and improve this sector.
