In the beginning of the year 2021, Bird Flu was confirmed among the migratory water birds at Pong Dam Lake Wildlife Sanctuary, Himachal Pradesh. The disease then killed more than 5000 birds. It was contained in February 2021. However, it has resurfaced since late March.


With the Second Wave of Bird Flu, around 99 birds recently were found dead at Pong Dam Lake. The officials of National Institute of High Security Animal Diseases have confirmed that the death of birds is due to the presence of H5N8 Avian Influenza. However, this strain is different from the previous outbreak. Previously the outbreak was due to H5N1. The bird fatalities are higher during days of adverse weather as it is when the geese tend to flock together instead of flying out.
