To prevent the spread of highly pathogenic avian influenza (H5N1), the Philippines has expanded its ban on poultry imports to include Indiana, New York, and Pennsylvania, in addition to previously restricted states. The ban encompasses all domestic and wild birds and their products. This action follows multiple H5N1 outbreaks in these US states during January and February. The Department of Agriculture cites the rapid spread of the virus as justification for the broader trade restrictions.

A new H5N1 avian flu variant, D1.1, has been detected in Nevada dairy cows, marking the first documented instance of this strain’s transmission from wildlife to domestic cattle. Seven herds, totaling approximately 50,000 cows, are currently under quarantine. While a few human cases of mild conjunctivitis have been reported, the risk to the general public remains low due to pasteurization of milk products and the illegality of raw milk sales in Nevada. The Nevada Department of Agriculture is actively monitoring the situation, implementing biosecurity measures on affected farms, and collaborating with federal agencies to investigate the virus’s spread.

Philadelphia reported its first suspected case of avian flu after a snow goose tested positive. This marks the city’s first case within a nationwide outbreak impacting poultry and increasing egg prices. Public health officials urge residents to avoid contact with sick or dead birds and report sightings. While the risk to humans remains low, concerns exist about potential human-to-human transmission should the virus continue to spread from birds to humans. Contact information for reporting sick birds or concerns about pets is provided.

In the past month, highly pathogenic avian influenza has impacted nearly 12 million birds, necessitating culling of entire flocks and driving up egg prices. This surge in avian flu cases coincides with a temporary halt in the release of public health communications from US agencies, including a CDC report on the outbreak. The suspension affects crucial information regarding the bird flu’s impact on poultry farms. This delay hinders efforts to address the crisis and could exacerbate the ongoing price increases.

Highly pathogenic avian influenza outbreaks have been confirmed at seven poultry farms across Aichi and Chiba prefectures, necessitating the culling of approximately 1.44 million birds. Three affected farms are located in Aichi Prefecture (two in Handa, one in Tokoname, and one quail farm in Agui), while three additional farms are situated in Chiba’s Choshi and Asahi cities. This brings the nationwide total of confirmed bird flu cases this season to 39. In response, the Ministry of Agriculture, Forestry and Fisheries established response headquarters in both prefectures to coordinate eradication efforts and prevent further spread.
