WCIA-TV News (May 1) – Dr. James Lowe, a professor of veterinary clinical medicine, said the H5N1 virus mostly impacts farm animals — usually birds and cows. It can pass around as one bird ingests the fecal matter of another infected bird. Currently, experts don’t have a solid explanation as to how it passes from birds to mammals or how it can transmit between cows, but the working theory is that it’s the result of cows getting exposed to infected birds in some way.
