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.

Learn about our community's health and wellness, compare indicators for your community against state averages, county values, and target goals. Discover areas of excellence and improvement in your community.
The Health Priority Index (HPI-Fresno) compiles data from national, state, and local sources to provide a visual depiction of the level of health burden within each census tract in Fresno County.
More information about the HPI-Fresno can be found here.
The Office of Environmental Health Hazard Assessment (OEHHA), on behalf of the California Environmental Protection Agency (CalEPA), released Version 4.0 of the California Communities Environmental Health Screening Tool (CalEnviroScreen). CalEnviroScreen identifies California communities by census tract that are disproportionately burdened by, and vulnerable to, multiple sources of pollution.
California Community of Burden of Disease Engine
CDPH has designed a comprehensive interactive tool to explore over 15 years of California condition-specific mortality burden data, using a range of measures, displayed at the statewide, county, community, and census tract levels, with interactive rankings, charts, maps and trend visualizations. The public tool is a work in progress and was designed for use by health departments and community partners to provide systematic scientific insight to inform public health planning, evaluation, and action.
Office of Statewide Health Planning and Development (OSHPD)
The Office of Statewide Health Planning and Development (OSHPD) dashboard provides data on patient characteristics in general acute case hospital settings in California by county and health care facility.
