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.

A review of over 1,500 research papers revealed a 90% mortality rate among pregnant women infected with bird flu, with 87% of their babies also succumbing. This alarming finding, based on 30 confirmed cases across several countries, highlights the vulnerability of pregnant women to this virus, despite the overall rarity of human infections. The lack of safety data currently prevents the inclusion of pregnant women in avian influenza vaccine trials, creating a significant public health concern. While the risk of a pandemic remains low, the study underscores the need for research into protecting this vulnerable population.

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 new federal order mandates nationwide testing of the milk supply for the H5N1 bird flu strain affecting dairy cows in 15 states. The USDA aims to swiftly identify infected herds and curb transmission, beginning testing in six states on December 16th. This initiative complements existing regulations requiring testing of cows before interstate transport and reporting of positive cases. The order addresses the escalating spread of avian flu in livestock and concerns about potential human health risks, particularly given the rise in raw milk consumption.

A recent surge in human H5N1 (bird flu) infections, including three cases with unknown origins, has public health experts deeply concerned about a potential pandemic. The detection of bird flu in a California raw milk sample further highlights the risk, particularly given the incoming administration’s stance on raw milk consumption. Concerns are amplified by a fragmented response to the outbreak, hampered by economic interests of dairy farmers and potential cuts to public health agencies. Experts urge the incoming administration to prioritize proactive measures, including enhanced surveillance, biosecurity, and research into rapid testing and vaccines, to prevent a major health crisis. Failure to address these issues effectively could exacerbate existing tensions between public health and the agricultural sector.

California’s public health department recently announced a potential case of avian influenza (bird flu) in a young child presenting with mild symptoms. This announcement naturally sparked concerns, especially given the child’s attendance at daycare, leading to the offering of testing and treatment to those who had contact with the child. The department, however, emphasized that there’s no current evidence of human-to-human transmission, reassuring parents and caregivers that based on existing data, the child wasn’t likely infectious. This statement is backed by the fact that no documented human-to-human spread of this particular strain of bird flu has been observed globally for over fifteen years.… Continue reading
The CDC has confirmed Oregon’s first human case of bird flu, a development that understandably raises concerns, but thankfully, health officials emphasize that there’s currently no evidence of person-to-person transmission. The individual infected experienced only mild illness and has fully recovered, a reassuring sign for the public. This case was identified through the close monitoring of individuals exposed to an animal outbreak in Clackamas County, highlighting the effectiveness of proactive surveillance programs. The low risk to the general public at this time is largely attributed to the lack of human-to-human spread.
However, this single case shouldn’t be interpreted as a complete lack of risk.… Continue reading
A Canadian teenager is in critical condition with suspected bird flu, marking the first known human case of the virus acquired in Canada. The teen, who experienced red eyes, fever, and cough, has progressed to acute respiratory distress syndrome. While the source of infection remains unknown, officials are investigating potential exposures to birds and other animals. Although the public health risk is considered low, the case underscores the seriousness of H5N1 and the need for continued vigilance in preventing further spread.

A new study by the CDC has revealed that 7% of dairy workers who were exposed to H5N1-infected cows in Michigan and Colorado have antibodies to the virus, highlighting a significant gap in existing protections and a lack of awareness among workers. This finding, coupled with the upcoming flu season and potential for reassortment with other influenza variants, underscores the urgent need for expanded testing, treatment, and protective measures for agricultural workers, especially those who may be hesitant to seek medical attention due to immigration status or fear of job loss. The CDC is now taking steps to address these concerns by offering wider testing, providing access to antivirals, and improving guidance on personal protective equipment, aiming to prevent the virus from gaining the ability to spread easily between humans and potentially triggering a new pandemic.

Canada has detected its first presumptive human case of H5 bird flu, raising concerns about the potential for another pandemic. While this is a significant development, it’s important to remember that the current public health risk is low. The virus, while deadly to birds and capable of infecting humans, has not yet shown signs of human-to-human transmission.
This particular case in Canada is believed to have originated from contact with birds. This highlights the importance of remaining vigilant about the virus and its potential spread. The CDC has identified 46 human cases of bird flu since April, most of which were linked to contact with infected poultry or dairy cows.… Continue reading
