Epidemiology & Statistics

Preventing diseases and injuries among Defiance County residents is a primary goal for all staff at Defiance County Public Health. Epidemiologists work hard to conduct disease and injury surveillance through ongoing collection, analysis, and reporting of public health data. These assessments are used to characterize the Who, What, When, Where, and Why of public health issues that are important to our community. Please note, some data may be unavailable due to the ongoing COVID-19 response. Click the links below to view the epidemiology reports.

What is Epidemiology

eh · puh · dee · mee · aa · luh · jee

Epidemiology is the foundation of public health and is defined as the study of the “distribution and determinants” of diseases or disorders within groups of people, and the development of knowledge on how to prevent and control them. Epidemiological research helps us understand not only who has a disorder or disease but why and how it was brought to this individual or region.
