Bird Flu update for 02-17-2025

As of the latest updates, the H5 bird flu, also known as avian influenza A(H5N1), continues to be a significant concern in the United States and globally. Here are the key points from recent developments: ### Outbreaks and Cases The bird flu outbreak remains widespread in the U.S., with cases reported in every state and the territory of Puerto Rico. As of late January 2025, there have been 67 reported human cases of H5N1 avian influenza in the U.S., resulting in one death, a 65-year-old Louisiana man with underlying health conditions who was likely exposed to the virus from wild birds and a non-commercial backyard flock[2][3][5]. ### Animal Infections The virus has affected a large number of animals, including over 12 million birds in the last 30 days, involving 54 commercial flocks and 55 backyard flocks. Additionally, there have been 928 dairy herd infections in 16 states, primarily in California[3]. ### Public Health Risk Despite the increasing number of cases, the Centers for Disease Control and Prevention (CDC) continues to assess the public health risk as low for the general public. However, certain groups such as farm workers, backyard bird flock owners, animal care workers, and public health responders are at a higher risk due to their exposure to sick animals or their byproducts[1][3][5]. ### Recent Developments In Maryland, the bird flu outbreak has led to the confirmation of highly pathogenic H5 avian influenza in several commercial poultry farms and a backyard flock. State officials have quarantined affected premises and depopulated the birds to prevent the spread of the disease. No infected meat or eggs have entered the food supply[3][4]. ### Health Advisory The CDC has issued a health advisory urging healthcare workers to accelerate testing for avian influenza A(H5N1) in patients hospitalized with flu symptoms. Healthcare providers are recommended to perform tests within 24 hours of hospital admission and start antiviral treatment immediately without waiting for test results[5]. ### Global Context While the current focus is on the U.S. outbreaks, it is important to note that H5 bird flu is widespread in wild birds worldwide. The global monitoring and response efforts are critical in managing the spread and potential risks associated with this virus. ### Safety Measures To prevent the spread of avian influenza, poultry and livestock owners are advised to adopt strict biosecurity measures, including daily monitoring for signs of illness, reporting suspected cases, and ensuring proper handling and hygiene practices. The U.S. Food and Drug Administration has also emphasized that pasteurized milk and properly cooked poultry and eggs remain safe for consumption[3][4]. In summary, while the bird flu situation is being closely monitored and managed, the risk to the general public remains low. However, continued vigilance and adherence to biosecurity measures are crucial in mitigating the spread of the virus.
