Third U.S. Bird Flu Case Sparks New Concerns

A third U.S. farm worker has tested positive for bird flu, raising concerns about the virus's transmissibility. The latest case in Michigan shows respiratory symptoms, unlike previous cases. Experts, including Dr. Suman Radhakrishna, indicate that the H5N1 variant does not appear to spread between humans. The CDC has not reported any human-to-human transmission, and the general population's risk remains low. The USDA is investing $800 million in testing, surveillance, and vaccine development, while the CDC is stockpiling bird flu vaccines. Health officials advise farm workers to use protective gear and get flu shots.
