The U.S Geological Survey has released its 2021 Winter Update on Highly Pathogenic Avian Influenza Viruses Circulating Globally in Wild Birds. According to the report, multiple strains of highly pathogenic avian influenza (HPAI)viruses have been detected globally in wild birds and poultry in 2021. This apparent increase in virus activity noted during the fall migration period warrants increased vigilance by North American wildlife health professionals. Wildlife managers can contact the USGS National Wildlife Health Center (NWHC) to report wildlife mortality events and to discuss submitting carcasses for diagnostic evaluation.

Recently, USDA APHIS has issued temporary restrictions on importation for some areas where HPAI is present. Visit the APHIS website for more details. The OC’s Import Guide provides guidance about importing samples from countries where HPAI has been detected. 

For information about HPAI, as well as West Nile virus and other zoonotic diseases that is pertinent for ornithologists and bird banders, read the Ornithological Council’s fact sheet.

More information about HPAI and the USDA APHIS’s  plan for avian influenza surveillance in wild birds is available here

The full text of the USGS Update is attached and will also be available here soon.
