Avian flu, or H5N1, has devastated US poultry farms, killing over 156 million birds and causing egg prices to surge. Farmers are implementing stringent biosecurity measures, but the crisis continues, forcing difficult decisions like accepting chicks from potentially infected areas to avoid leaving farming. The outbreak’s worsening coincides with proposed government funding cuts to research and response efforts, raising concerns about pandemic preparedness. The Trump administration is developing a new strategy focused on prevention and vaccination, while moving away from culling infected flocks, although the effectiveness of this approach is debated.

The USDA accidentally fired several employees involved in the federal response to the H5N1 avian flu outbreak over the weekend. The agency is working to immediately reverse these firings, classifying these positions as crucial to public safety and food supply. These layoffs, part of broader government cuts, caused concern among Republican lawmakers who warned of potential harm to the bird flu response. The incident highlights the challenges and unintended consequences of rapid government downsizing.

Ohio has confirmed its first human case of bird flu (H5N1) during the current outbreak, affecting an adult farmer in Mercer County who had contact with infected poultry. The risk to the general public remains low, according to the CDC. The state health department advises avoiding contact with sick or dead poultry and wild birds, and recommends using protective equipment when handling potentially infected animals. Further guidance emphasizes thorough handwashing and avoiding touching one’s face after contact.

A new avian influenza variant (H5N1 D1.1) has infected dairy cattle in Nevada, exhibiting a mutation enabling more efficient replication in mammals. This mutation, unseen in other D1.1 strains, raises concerns about increased human transmission risk, particularly for those working with livestock. A farm worker has already tested positive for H5N1 in Nevada, displaying symptoms including conjunctivitis. The virus’s origin is currently under investigation, with theories suggesting transmission via wild birds or another intermediary animal.

Following the detection of avian flu in several New York City boroughs, all live poultry markets in the city and surrounding suburbs are temporarily closed for one week as a precaution. The H5N1 strain, impacting over 156 million birds nationwide, has led to the culling of millions and significantly increased egg prices. While the CDC reports a low risk to the general public, affected markets must dispose of their poultry and undergo thorough cleaning and disinfection before reopening. The closures aim to prevent further spread of the highly contagious virus.

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.

A recent human death from avian influenza (H5N1) in Louisiana, linked to exposure from infected backyard chickens, highlights the virus’s increasing threat to humans. The virus has shown concerning mutations mirroring a similar case in British Columbia, increasing its potential for human-to-human transmission. Widespread influenza testing, while helpful for monitoring, also raises concerns about potential viral reassortment, creating a more dangerous strain. Sustained animal-to-animal transmission in mammals like ferrets and dairy cows further fuels this threat, emphasizing the need for increased surveillance and biosecurity measures within the dairy industry and other animal sectors.

A Stanford University study found that influenza A viruses can remain infectious in refrigerated raw milk for up to five days, highlighting a potential human health risk. This research, using an H1N1 strain, suggests raw milk is a viable transmission route for similar viruses, including the currently circulating H5N1 avian influenza affecting dairy cows. Pasteurization effectively eliminates the virus, emphasizing the importance of this process. The study’s findings underscore the dangers of raw milk consumption, particularly given the current H5N1 outbreaks and the persistence of raw milk’s popularity despite associated risks.

Governor Newsom declared a state of emergency in California due to a rising number of bird flu cases affecting both birds and, notably, dairy cows. This action, mirroring a similar declaration in Colorado, provides increased funding and flexibility for state agencies to combat the spread. While human-to-human transmission remains nonexistent in California, the state has already implemented measures to minimize farmworker exposure, many of whom have contracted the virus. Although the risk to the public is currently low, the severity of H5N1 bird flu in humans necessitates proactive measures.

A California child fell ill with flu-like symptoms after consuming raw milk from Raw Farm, prompting an investigation into a potential H5N1 bird flu case. Initial CDC tests for H5 flu were negative, though further testing is ongoing. The milk producer, Raw Farm, had already recalled several lots of milk and cream after bird flu was detected in their products. The child recovered fully, and there is no evidence of human-to-human transmission.
