Feline Surveillance Urged as Bird Flu Threats Rise

Domestic cats might play an unforeseen role in the evolution of the bird flu virus H5N1, raising alarms among public health experts. Recent studies indicate that since the H5N1 strain began affecting dairy cattle, various cats—especially those on farms—have fallen ill or died due to the virus. To date, H5N1 has led to the illness of at least 60 individuals, mainly those interacting closely with infected livestock or poultry.Although the H5N1 virus does not readily spread between humans, its ability to mutate is a potential threat. Experts caution that should a cat become co-infected with both H5N1 and a seasonal flu strain, it could acquire critical mutations necessary for efficient human transmission. Veterinary microbiologist Dr. Suresh Kuchipudi, who contributed to the study, urges health authorities to enhance surveillance for avian flu in felines, which often mingle with both wild animals and humans. Furthermore, the U.S. has seen slow testing rates for H5N1 in cattle and humans, prompting the Department of Agriculture to begin evaluating the national milk supply for signs of infection, hoping to uncover the full extent of the outbreak in dairy farms.
