A veterinarian says new cases of highly pathogenic avian influenza suggest dairy cattle aren’t just contracting the virus from infected birds.
Dr. Keith Poulson with the Wisconsin Veterinary Diagnostic Laboratory says they continue to monitor its spread. “The Michigan and Idaho herds, they were the first ones to suggest that maybe this isn’t just a point source infection from birds and a water source, which is what we thought for about two or three weeks, and there is a potential now for lateral transmission or cow-to-cow infection.”
Poulson says the virus is affecting cattle much differently than poultry.
