Contact Tracing Unit

Vision: The vision of the Contact Tracing Unit is reduced burden of infectious disease in all Marylanders.

Mission: The Contact Tracing Unit works with local health departments and other community partners to stem the tide of infectious diseases, including COVID-19, through contact tracing. We ensure quick and efficient outreach to all Marylanders to employ appropriate mitigation strategies and facilitate connections to treatment, needed resources, and support services.


HAPPENING NOW: Contact Tracing Evaluation 

The Contact Tracing Unit at the Maryland Department of Health is currently conducting an evaluation of the contact tracing program. Maryland residents who were called by contact tracers during the pandemic will receive a text message or email from the health department asking them to complete a brief survey. If you have questions about this evaluation, please contact us at mdh.ctsurvey@maryland.gov. Thank you! 

What Is Contact Tracing?

Contact tracing is the process of identifying people who may have come into contact with an individual who has an infectious disease. Through contact tracing, we can better understand disease transmission, prevent new infections, and help slow the spread of infectious diseases like COVID-19 and Ebola virus disease.

What Is MD COVID Alert?

MD COVID Alert is the official COVID-19 Exposure Notifications Express system of Maryland. This system was developed to assist, but not replace, Maryland’s contact tracing efforts.

MD COVID Alert uses Bluetooth Low Energy technology to quickly notify users who might have been exposed to someone who tested positive for COVID-19. This will help Maryland stop the spread of COVID-19.
