News Release, St. Mary’s County Health Department

LEONARDTOWN, MD (March 26, 2020) – The Calvert County Health Department has announced the following potential public exposure risk relating to a confirmed positive case of COVID-19 in a Calvert County resident:

7-Eleven, 3675 Hallowing Point Rd, Prince Frederick, MD 20678
Dates: March 12 – 25, 2020

Community members who were also at this location during the specified dates may be at some risk for acquiring COVID-19 and should:

  • Self-monitor for symptoms of a respiratory infection including fever, flu-like symptoms, cough, or shortness of breath until 14 days have passed from the date of exposure 
  • Stay home as much as possible
  • Take additional precautions of washing hands frequently and avoid contact with people over age 60 and people of any age with weakened immune systems

Out of an abundance of caution, the 7-Eleven regional office has closed the regional franchises, including Prince Frederick and Mechanicsville (28240 Three Notch Rd) stores. At this time, there is no known exposure risk associated with the Mechanicsville location. The St. Mary’s County Health Department will notify residents immediately if an exposure risk is determined for this location through the ongoing investigation. 

If you develop symptoms:

  • Call your healthcare provider 
  • If you do not have a healthcare provider and are a St. Mary’s County resident, call the St. Mary’s County COVID-19 Community Hotline (Monday – Saturday from 8:00 a.m. to 5:00 p.m. at 301-475-4911) to speak with a Health Department nurse  
  • Self-isolate – Remain at home until you receive instructions about the next steps from your healthcare provider or local health department. Stay at least 6 feet away from others. If possible, do not share a bathroom or bedroom with others in your household. 
  • Those with mild symptoms can stay home. If symptoms worsen or you need medical attention, call ahead before going to your doctor’s office, urgent care or emergency department. Use 9-1-1 if in a medical emergency and notify dispatch of your potential exposure concerns.

The Southern Maryland Chronicle is a local, small business entrusted to provide factual, unbiased reporting to the Southern Maryland Community. While we look to local businesses for advertising, we hope to keep that cost as low as possible in order to attract even the smallest of local businesses and help them get out to the public. We must also be able to pay employees(part-time and full-time), along with equipment, and website related things. We never want to make the Chronicle a “pay-wall” style news site.

To that end, we are looking to the community to offer donations. Whether it’s a one-time donation or you set up a reoccurring monthly donation. It is all appreciated. All donations at this time will be going to furthering the Chronicle through hiring individuals that have the same goals of providing fair, and unbiased news to the community. For now, donations will be going to a business PayPal account I have set-up for the Southern Maryland Chronicle, KDC Designs. All business transactions currently occur within this PayPal account. If you have any questions regarding this you can email me at

Thank you for all of your support and I hope to continue bringing Southern Maryland the best news possible for a very long time. — David M. Higgins II
