New Jersey Reports First Feline Case of H5N1 Avian Influenza
The United States Department of Agriculture (USDA) has confirmed the first case of highly pathogenic avian influenza (HPAI) H5N1 in a feral cat in New Jersey. This follows reports of feline H5N1 cases in other states. The infected cat exhibited severe neurological symptoms and was humanely euthanized. Investigations are ongoing regarding other potentially infected cats on the same property. While the overall public health risk remains low, this case highlights the zoonotic potential of H5N1, particularly in animals with close contact to infected poultry

Indiana Bird Flu Outbreak Escalates, Impacting Poultry and Wildlife
Indiana is experiencing a significant surge in highly pathogenic avian influenza (H5N1), impacting both commercial poultry and wild bird populations. Nearly 7 million poultry birds have been affected across 20 facilities, primarily in Jay and Jackson counties. The outbreak has also led to the deaths of an estimated 1,500 sandhill cranes and other waterfowl throughout the state. The current H5N1 strain, identified in 2021, is highly contagious and persistent. While the risk to humans remains low, the outbreak has led to soaring egg prices, prompting the USDA to announce a $1 billion strategy to curb the spread and stabilize the market
