Epidemiology is “the study of the distribution and determinants of health and disease in a population”. To put it more simply, epidemiologist are “disease detectives” who use data to answer questions like: Who is getting sick? What is making them sick? Where is the problem occurring? When is the problem occurring? Why are some people more effected? How big is the health problem in our population? How can we better understand the disease? How can we prevent others from getting sick?

The Epidemiology Program is a part of the Division of Epidemiology, Surveillance, & Data Management within the Fresno County Department of Public Health. The Epidemiology Program focuses on the health of the various populations that make up the Fresno County community. The primary aim of the Program is to use data to monitor and improve the health of the local community. Epidemiologists in collaboration with other Department of Public Health programs, participate in disease surveillance and health data collection; disease investigation; data analysis, assessment, and management; and health communication. The Program works with other units within the Department as well as providing services to other agencies and the public.
