The Prince George’s County Health Department, along with the MDH, recommends members of the public who attended or worked this event monitor themselves for symptoms of a respiratory infection including fever, cold-like symptoms, cough, or shortness of breath.

Persons who attended or worked this event should check their temperature twice a day and notify their health care provider and local health department if their temperature exceeds 100.4 or if they develop a respiratory illness. They should remain at home until they receive instructions about next steps from their health care provider or local health department.

The Health Department is working closely with our state and federal partners and is committed to keeping all residents, employees, and visitors to Prince George’s County safe and healthy. This continues to be a rapidly evolving situation so it’s even more important to keep yourselves and your communities informed about COVID-19 and the latest updates by visiting We also continue to encourage Prince Georgians practice the same cold and flu season preventive measures to avoid this novel coronavirus and other respiratory illnesses.
