Kathmandu, April 7 (NationPress) The highly pathogenic avian influenza, known as H5N1 or bird flu, has recently spread to four districts in Nepal, according to a government representative on Tuesday.
The dangerous virus has been confirmed in 23 poultry farms located in Morang, Sunsari, Jhapa, and Chitwan districts. Indira Sharma, an information officer from the Department of Livestock Services, informed Xinhua that the initial detection of bird flu occurred in Morang district on March 18.
“We are making every effort to prevent further spread,” Sharma stated to Xinhua.

The H5N1 influenza virus is among various strains that lead to a highly contagious respiratory disease in birds, commonly referred to as avian influenza or bird flu. Cases of infection in mammals, including humans, have also been reported.
In humans, H5N1 infection can cause a spectrum of illnesses, ranging from mild to severe, and in some instances, it can be deadly. Common symptoms reported are primarily respiratory, although conjunctivitis and other non-respiratory symptoms have also surfaced. Some cases of the A(H5N1) virus have been identified in individuals who were exposed to infected birds or their environments without showing any symptoms.
The goose/Guangdong-lineage of H5N1 avian influenza viruses first appeared in 1996 and has been responsible for outbreaks in birds ever since. Since 2020, a variant of these viruses has resulted in an unprecedented number of fatalities among wild birds and livestock across various nations. Initially impacting Africa, Asia, and Europe, the virus made its way to North America in 2021 and then to Central and South America in 2022. During 2021 and 2022, Europe and North America experienced their most significant and prolonged avian influenza epidemic, with the virus showing unusual persistence in wild bird populations.
