Epidemiology is the branch of public health that focuses on investigating patterns of disease and measuring the health of a community. A key function of epidemiology is to collect data through surveillance and reporting systems to look for trends and patterns of disease in the community. Data can highlight both the existence of problems and opportunities for improvement. It can also guide local action in support of policy changes and improve programs’ effectiveness. It also helps users prioritize needs, mobilize local resources, tap state and national resources, and act on opportunities to promote health.
Types of Data
Primary data are collected first-hand through surveys, listening sessions, interviews, and observations
Secondary data are collected by another entity or for another purpose
Indicators are secondary data that have been analyzed and can be used to compare rates or trends of priority community health outcomes and determinants
We are committed to using and sharing data to ensure positive outcomes at the program and population level. We use gathered information to design, target, and evaluate programs that meet specific community needs.
