The Johnson County Board of Supervisors held a work session on December 18, 2024, focusing on the recent detection of highly pathogenic avian influenza (H5N1) in local wastewater. Public health officials, including Danielle Peterman and Sam Jarvis from Johnson County Public Health, provided an update on the situation, emphasizing the importance of monitoring and preventive measures.

The meeting highlighted that the detection of H5N1 in wastewater was reported earlier in December, marking the second occurrence this year. This surveillance is part of a national effort led by the CDC and USDA to track the virus's spread. Officials noted that while the detection is concerning, it does not currently indicate human-to-human transmission. They stressed the significance of wastewater monitoring as a tool for public health, allowing communities to make informed decisions regarding health precautions.

A key point of discussion was the importance of seasonal influenza vaccinations. Public health representatives urged dairy farm workers and the general public to get vaccinated against seasonal flu to reduce the risk of complications that could arise from potential H5N1 outbreaks. Dr. Melanie Wellington, a pediatric infectious disease specialist, explained that vaccination could help prevent the mixing of flu virus strains, which could lead to new, more dangerous variants.

The meeting also addressed the ongoing public health messaging regarding the consumption of raw milk, which poses additional health risks. Officials reiterated that raw milk can be a source of various pathogens, including those related to avian influenza, and emphasized the need for pasteurization to ensure safety.

In conclusion, the Board of Supervisors underscored the importance of continued surveillance and public health education to mitigate the risks associated with H5N1 and seasonal influenza. They encouraged residents to stay informed and proactive in their health decisions, particularly regarding vaccinations and safe food practices.
