The District of Columbia Department of Health (DC DOH) relies on various partners, including healthcare facility staff, school nurses, and laboratory staff to provide us with information about diseases that can spread in the community or are of public health concern. We use this information to monitor the health of District residents, identify and investigate potential outbreaks, evaluate the effectiveness of public health interventions, and contribute to the national surveillance data collected by the Centers for Disease Control and Prevention (CDC).

Notifiable Diseases and Conditions

To help prevent and control the spread of communicable diseases in the District of Columbia, all health care providers are required by law to report certain diseases and conditions to the DC Department of Health (DC DOH) according to Chapter 22-B2 of the District of Columbia Municipal Regulations.

To view the list of notifiable diseases and conditions to be reported to DC DOH, please review the following document: Notifiable Diseases and Conditions in DC
