The risk of a bird flu pandemic is rising

The risk of a bird flu pandemic, particularly from the H5N1 virus, is increasing in the United States due to rising human infections and the virus's spread among dairy cattle. As of now, 55 human cases have been reported, primarily linked to contact with infected animals. The virus has also been detected in pigs and dairy products, raising concerns about its potential to mutate and spread among humans. While vaccines for H5N1 are available, experts stress the need for more testing and vaccination of dairy farm workers to prevent further outbreaks. The USDA has reported the virus in 675 herds across 15 states, and there are fears that the virus could evolve into a more infectious strain. Current testing protocols vary by state, and there is uncertainty about how the virus spreads between farms. Although pasteurization is believed to inactivate the virus, there are concerns about its presence in milk products. Experts warn that the situation is reminiscent of the early stages of the 2009 H1N1 pandemic, emphasizing the urgency of addressing the issue before it escalates into a global health crisis.
