One Health Epidemiology Program

Page last updated 08/05/2026.

One Health is an approach that recognizes the health of people, animals, plants, and our shared environment are all connected. The County of San Diego’s One Health Epidemiology Program (OHEP) is made up of epidemiologists, communicable disease investigators, veterinarians, nurses, healthcare providers and laboratorians. They work with the community to prevent zoonotic diseases and address other One Health concerns.
