“Our county is now demonstrating high community spread of COVID-19, mostly affecting adults and youth who are not yet fully vaccinated. Ready access to testing and vaccine for this illness is critical to controlling the surge we are experiencing. This new location is easily accessible, even to those without cars,” said Dr. Meena Brewster, St. Mary’s County Health Officer. “The best thing you can do for your health and your community right now is to get vaccinated. Please get tested if you are having COVID-19 symptoms or have been exposed to someone with COVID-19.”

Community members showing any sign or symptom of COVID-19 should get tested within 24-48 hours, regardless of vaccination status or prior infection. Asymptomatic persons exposed to COVID-19 who are not yet fully vaccinated are also encouraged to get tested.
