For more information, phone (619) 542-4092.

Our goal is to help reduce and eliminate health disparities by providing information about health conditions, including infectious and chronic diseases, which affect various populations differently.  Key influencing factors (i.e., social determinants of health) include, for example, age, geography, gender, race/ethnicity and socio-economic status. Our REHDI resource page includes key definitions, links to health equity reports and other resource links.

Our Health Equity Vision: Health equity for all San Diego County residents.

Our Health Equity Mission: Public Health Services (PHS) is committed to increasing health equity in San Diego County through continual development of policies and procedures, community capacity, awareness, and operational responsiveness and support to staff.
