Avian influenza detected in American dolphin
8 September, 2022
A bottlenose dolphin found dead in Florida’s Dixie County was infected with the highly pathogenic avian influenza virus, making it the first cetacean to be found with the virus in America and only the second known case in the world.
The young male dolphin was recovered in March at Horseshoe Beach by the University of Florida’s marine animal rescue team. A collaboration between UF College of Veterinary Medicine researchers and state and federal laboratories identified the unexpected infection with HPAIV.
The virus recovered from the dolphin belonged to clade 2.3.4.4b of the Eurasian H5 viral lineage.
