San Francisco's public health officials are actively monitoring the ongoing avian influenza outbreak, particularly the H5N1 strain, which has recently impacted dairy herds across California. During a recent government meeting, Dr. George Hahn, the communicable disease section director, provided a comprehensive update on the situation, emphasizing the collaborative efforts of various health teams in the city.

As of December 31, 2024, there have been 66 confirmed human cases of H5N1 in the United States, with 37 of those in California, primarily among dairy workers. Notably, no cases have been reported in San Francisco. Dr. Hahn reassured the public that the risk to the general population remains low, as the virus has not shown the ability to spread easily between humans.

The presentation highlighted the significant impact of H5N1 on California's dairy industry, with over 650 dairy herds affected statewide. This has prompted the state to declare a state of emergency to facilitate a swift response to the outbreaks. The public health laboratory in San Francisco is actively testing flu specimens and monitoring wastewater for signs of the virus, although current findings suggest that detected H5N1 is likely from environmental sources rather than human transmission.

Dr. Hahn also addressed concerns regarding the availability of vaccines for H5N1, noting that while vaccines exist, they have not yet been distributed due to limited supply. The health department is preparing for various scenarios, including the potential for human cases to arise in San Francisco, and is committed to keeping the public informed.

In conclusion, the city's health officials are taking proactive measures to monitor and respond to the avian flu situation, ensuring that they are prepared for any developments while maintaining public safety. The ongoing collaboration among health teams and the emphasis on communication will be crucial as the situation evolves.
