BEIJING: The United Nation's Food and Agriculture Organization on Thursday (July 25) called for an urgent and unified response to combat an "alarming" rise in avian influenza cases in humans and animals across the Asia-Pacific.
The H5N1 virus has spread more widely than ever before, reaching as far as South America and Antarctica and infecting new wild and domestic animals, it said in a statement.
"Since late 2023, we have observed a rise in human cases and the virus spreading to new animal species," said Kachen Wongsathapornchai, regional manager of the FAO's Emergency Centre for Transboundary Animal Diseases.
"The emergence of novel A/H5N1 strains, which are more easily transmissible, increases the pandemic threat. Immediate, coordinated preventive measures are essential."
The UN agency counted 13 new human infections reported in Cambodia since late 2023, with additional cases in China and Vietnam.
Indonesia and the Philippines are facing heightened security due to its diverse ecological landscape and limited biosecurity measures, while India, Nepal and Bangladesh are also battling outbreaks, it said.
It urged member nations to work together to implement comprehensive surveillance systems, including full genome sequencing, to track the virus's spread and evolution.
It also called on governments, international organisations and the private sector to share information transparently, and stressed the need for the poultry industry to strengthen biosafety measures.
Bird flu spreads to farmed animals from wild birds.
The H5N1 strain of avian flu has swept the globe in recent years, killing billions of farmed and wild birds and spreading to tens of mammal species.
Australia, which is dealing with three parallel outbreaks of bird flu, reported a human H5N1 case in May.
Earlier this year, a Chinese woman died from a rare H3N8 subtype of avian influenza, the world's first death from the strain.
Scientists tracking the spread of bird flu are increasingly concerned that gaps in surveillance may keep them several steps behind a new pandemic, according to Reuters interviews with more than a dozen leading disease experts. - Reuters
