Welcome to the Office of AIDS (OA). OA is a division within the California Department of Public Health, Center for Infectious Diseases.
OA works collaboratively with state and federal agencies, local health jurisdictions, universities, and community-based organizations to ensure that efforts to combat the HIV/AIDS epidemic are targeted and effective.
We invite you to use our website and hope that you find it informative and easy to navigate. OA’s website provides HIV/AIDS resources and information on HIV testing and prevention; HIV care services; AIDS drug assistance; insurance assistance; housing information and HIV/AIDS data, as well as other resources for individuals, service providers, researchers, and policymakers.
