Three veterinarians who work with cows have tested positively for earlier infections of H5 bird flu, according to a study released today by the Centers for Disease Control and Prevention.
The finding may not seem surprising, given the radical and continuous outbreak of H5N1 among dairy farms in the US, which has reached 968 herds in 16 states and led to infections in 41 dairy workers. However, it is remarkable that none of the three veterinarians was aware that they were infected, and none of them worked with cows that were known or suspected they were infected with H5N1. In fact, one of them only worked in Georgia and South Carolina, two states where H5N1 infections in dairy cows and people were never reported.
The findings suggest that the virus is possible in silence in animals and people, and that our surveillance systems are missing infections-so on long-term fears at health experts.
The authors of the study, led by researchers from the CDC, put the collection meals different and write: “These findings suggest the possible advantage of systematic supervision for rapid identification of HPAI A (H5) virus in dairy cattle, milk and people who people They are exposed to cattle to guarantee appropriate hazard reviews.
