The Association of Bay Area Health Officials (ABAHO) is a regional network of 13 local health jurisdictions in the San Francisco Bay Area. Since the early 1980’s the ABAHO network has brought together representatives from Bay Area health departments to address issues ranging from the emergence of the HIV/AIDS epidemic to pandemic influenza preparedness. Utilizing both a health officials committee and a public health preparedness subcommittee, the ABAHO network leverages the expertise and resources of local health departments to advance regional public health and promote communication and collaboration among neighboring counties.
