Six States Report HPAI-Infected Dairy Cows
A herd of dairy cattle in Ohio has been infected with highly pathogenic avian influenza (HPAI), increasing the number of states with dairy operations affected by the virus to six. The USDA previously confirmed the H5N1 strain of HPAI in dairy cattle on seven Texas farms, two in Kansas, and one each in New Mexico, Michigan, and Idaho.
The USDA’s Animal and Plant Health Inspection Service (APHIS) is not requiring dairy cattle to be tested for HPAI infection, although testing may be done on a voluntary basis. On April 1, APHIS issued a guidance document on testing cattle for HPAI.
APHIS issued another series of HPAI-related recommendations, this time for state animal health officials, accredited veterinarians, and producers, addressing such areas as biosecurity, monitoring of sick animals, worker safety, and movement of cattle.

AABP Promotes Cattle Disease as Bovine Influenza A
The American Association of Bovine Practitioners (AABP) has sent out a notice that they will now refer the recent virus in cattle as Bovine Influenza A Virus (BIAV).
In their press release the AABP said they have collaborated with veterinarians, allied organizations, state and federal agencies, diagnostic laboratories and animal health officials on the 2024 emerging disease event affecting dairy cattle. The virus isolated from affected animals in herds matching the clinical syndrome has been identified as avian influenza virus Type A H5N1. This virus causes Highly Pathogenic Avian Influenza in birds, however the disease syndrome in cattle does not cause high morbidity and mortality as it does in birds. The AABP does not believe that this disease should be referenced as “HPAI in cattle” or “bird flu in cattle” due to these differences.
