The recent spread of avian influenza among dairy cattle in the U.S. has raised concerns among scientists, although the risk to humans remains low for now. The virus, which first emerged among wild migratory birds in late 2021, has now been detected in dairy cows and a major egg producer, with one human infection reported. While the virus has shown minor changes, there is no evidence of significant mutations that would increase its danger to humans. Human-to-human spread of bird flu remains extremely rare, with cases typically linked to direct contact with sick animals. Although cows may be spreading the virus to each other, it's not proving to be deadly, and the commercial milk supply is not at risk due to pasteurization. However, sustained spread between mammals could potentially lead to more problematic mutations. Federal officials stress that the U.S. has been preparing for avian flu outbreaks for years, with limited stockpiles of vaccines available if needed. While there may be more human cases, the likelihood of widespread transmission remains very low at this time. Click here for article.
