Bird Flu Warning: Mutation Risk Signals Potential Pandemic
The current H5N1 avian flu outbreak shows concerning signs of escalating, with at least 65 human cases reported this year, including the first severe U.S. infection. Key indicators fueling concern include the virus’s widespread presence in wastewater, unidentified human infections, and research suggesting it may require fewer mutations to become easily transmissible between humans. These developments, coupled with efficient spread among dairy cows, increasing human exposure, and potential for mutation during co-infection with seasonal flu, raise the possibility of a pandemic. While the immediate public health risk remains low, experts emphasize the urgent need for expanded surveillance and preventative measures, including widespread milk testing and vaccination of both farm animals and high-risk human populations.
