U.S. bird flu cases decline but threat remains

Cases of bird flu, known as H5N1, are decreasing in the U.S., but experts warn that the threat remains. Although wholesale egg prices are falling and fewer sick birds are being destroyed, the spring migration of wild birds poses new risks for farms. In March, farmers have had to cull two million birds due to the virus. This is a significant drop from 12.7 million in February and 23.2 million in January. Additionally, new infections on dairy farms have also reduced, with only 12 reported in March compared to 17 in February. This drop in cases may be linked to fewer wild birds migrating over farms during the winter months. The infections on dairy farms are likely tied to an earlier outbreak, with fewer farms left to infect after the fall surge. Despite the drop in infections, some dairy farms still have sick animals. The Centers for Disease Control and Prevention (CDC) states the current risk to the public is low, but moderate to high for those in contact with infected animals. Only one person has died from the virus in the U.S., despite a high mortality rate observed in past cases. The CDC suggests prior infections with seasonal flu may protect people from severe illness from H5N1. Food products like chicken, eggs, milk, and beef are considered safe to eat. The FDA and USDA assure that pasteurization and proper cooking eliminate the virus. The USDA is investing $500 million in biosecurity and farmer support and is exploring new vaccines for poultry. Experts also recommend considering vaccination for hens to help control the virus.
