On March 4, 2017, APHIS’ National Veterinary Services Laboratories (NVSL) confirmed a case of highly pathogenic avian influenza (HPAI) H7N9 on a commercial broiler breeder farm in Tennessee. A second case of HPAI H7N9 in Tennessee was confirmed on March 15, 2017 on another commercial broiler breeder farm. This virus is NOT the same as the China H7N9 virus that emerged in 2013 and impacted poultry and humans in Asia. Additionally, APHIS found H7 low pathogenic avian influenza (LPAI) in six backyard flocks - three in Alabama, two in Tennessee, and one in Kentucky. APHIS also found H7 LPAI in six commercial broiler breeder flocks – one in Tennessee, three in Alabama, one in Kentucky and one in Georgia. Following these avian influenza findings, APHIS joined forces with the affected states and the poultry industry to complete a series of epidemiologic, genetic and wildlife investigations.
In the report, APHIS outlines the findings to date, which include:
