Epidemiology is defined as a method used to investigate the causes of health outcomes and disease in populations.


Rappahannock-Rapidan’s Epidemiology Program is responsible for protecting local residents from various communicable/infectious diseases. The epidemiology team investigates all conditions and diseases that are reportable per the Code of Virginia and the State Board of Health.

According to Section 32.1-37 of the Code of Virginia, healthcare professionals, facilities, laboratories, and other agencies who provided care to a patient who they suspected as having or died from a reportable disease are required to report using the Confidential Morbidity Report Portal. For more information on outbreak reporting requirements for facilities and programs please click this link.

Some of the services we provide include: community outreach, health education, outbreak management and response, and disease surveillance.
