H5N1 Avian Flu Outbreak in Cattle Sparks Pandemic Fears
The H5N1 avian flu strain, now widespread in U.S. dairy cattle, is raising alarms about its potential to evolve into a human-transmissible virus. Scientists at the CDC report that bulk milk testing, mandated in June 2025, has identified infected herds earlier, but the virus’s spread among mammals remains a concern. Vaccine trials in cows are underway, with results expected by late 2025. On X, discussions are trending about the risk of a new pandemic, with experts urging vigilance. “We’re watching closely for any signs of human-to-human transmission,” said virologist Dr. James Patel.
