CARSON COUNTY, Texas (NEWS RELEASE) - The National Veterinary Services Laboratories (NVSL) confirmed this week the presence of Highly Pathogenic Avian Influenza (HPAI) in a striped skunk recovered from Carson County.

This is the first confirmed case of HPAI in mammals for Texas.

Detected in all states across the U.S. except Hawaii, HPAI is a highly contagious virus that transmits easily among wild and domestic birds. The virus can spread directly between animals and indirectly through environmental contamination...

EPIDEMIOLOGICAL COMMENTS
Highly pathogenic avian influenza (HPAI) H5N1 Eurasian lineage goose/Guangdong clade 2.3.4.4b has been confirmed in samples from dairy cattle in Idaho (ID), Kansas (KS), Michigan (MI), New Mexico (NM), North Carolina (NC), Ohio (OH), South Dakota (SD) and Texas (TX). Updates to the detections of highly pathogenic avian influenza (HPAI) in livestock can be found at: https://www.aphis.usda.gov/livestock...ions/livestock. On 24 April 2024, The Animal and Plant Health Inspection Service (APHIS), United States Department of Agriculture issued a federal order requiring pre-movement testing and reporting of highly pathogenic avian influenza (HPAI) in livestock. Wildlife detections unrelated to dairy cattle detections are reported in Vermont (VT) and California (CA).
