The presence of H5N1 highly pathogenic avian influenza (HPAI) has recently been confirmed in seven poultry flocks in Nepal.

According to a report from the World Organisation for Animal Health, all but one of the affected flocks was in the Koshi province. The other was in the Bagmati province.

The affected flocks in the Koshi province included:

• 226,407 laying hens, ranging in age from 10 to 126 weeks
• 21,373 broiler breeders in three different age groups: 18, 43 and 57 weeks
• 19,499 laying hens, which were 18, 43 and 57 weeks old
• 5,000 laying hens, all 57 weeks old
• 60,237 laying hens, ranging in age from 10 to 75 weeks
• 4,200 Giriraja chickens, which were 22 weeks and 33 weeks old.

The Bagmati flock included 34,600 laying hens, ranging in age from 13 weeks to 36 weeks.

In each situation, according to WOAH, the flocks either had wild birds frequently visiting the premises, were close to a river where migrating birds were common, or were in close proximity to a previously HPAI-affected farm. In one of these instances, a feed truck that was potentially carrying the virus was listed as a possible source of infection.

Control measures applied included stamping out, disinfection, movement control, quarantine, screening, surveillance within a restricted zone, and official destruction of animal products, carcasses, byproducts and waste.
