Bird Flu update for 02-25-2025
As of the last 48 hours, the situation regarding the Bird Flu virus, specifically the highly pathogenic avian influenza (HPAI) H5N1, continues to evolve, particularly in the United States and other parts of the world.
In New York City, multiple birds have tested positive for H5N1 at parks, zoos, and live bird markets. Despite these positive cases, the risk to humans remains low, with no reported human cases of H5N1 in New York City or elsewhere in the state. The New York City Department of Health and Mental Hygiene (DOHMH) is taking precautionary measures, including providing support and antiviral medication to staff at live bird markets who may have been exposed. Live bird markets where the virus was detected have been temporarily shut down for cleaning and disinfection, and workers are advised to monitor their health for symptoms such as headaches, cough, fever, and shortness of breath[1].
In the broader context of New York State, HPAI has been confirmed in nearly 100 birds so far in 2025, with waterfowl and raptors being the most affected. The virus has also been detected in various wild mammals, including red foxes, a striped skunk, a Virginia opossum, a raccoon, and a bobcat. Recently, the first confirmed positive case of HPAI in an Eastern gray squirrel was reported[2].
Globally, the UK is also experiencing an outbreak. In England, an avian influenza prevention zone (AIPZ) with enhanced biosecurity measures has been extended to additional counties, including Herefordshire, Worcestershire, Cheshire, Merseyside, and Lancashire, in addition to existing areas. Mandatory housing measures for all kept birds are in force in several regions to prevent the spread of the disease. Bird gatherings of poultry, galliforme, or anseriforme birds have been banned since February 10, 2025[3].
The UK's measures include strict biosecurity protocols, surveillance zones, and the humane culling of poultry at affected premises. These actions are part of a broader effort to manage and monitor the risks of avian influenza.
In summary, while the risk to humans from H5N1 remains low, especially in the U.S., ongoing vigilance and stringent biosecurity measures are being implemented to contain and prevent the spread of the virus among bird populations. Public health officials continue to monitor the situation closely and provide guidance to the public and bird keepers to ensure safety and prevent further outbreaks.
