California HIV Statistics by County

  • Data for county totals of persons newly diagnosed with HIV infection and of people living with HIV are taken from the 2018 California HIV Surveillance Report (published on Feb 27, 2020 by the California Department of Public Health, Office of AIDS).
  • Race/ethnicity data are taken from the AtlasPlus tool provided by the CDC National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP).
  • The 2018 AtlasPlus data on new HIV diagnoses are preliminary and based on a 6-month reporting delay. County-level race/ethnicity data are withheld for confidentiality, if the population denominator is less than 100 or total case count is 1-4.
