2 Cases of Measles Reported in So. MD

Maryland Department of Health confirmed that two cases of measles have been identified in residents of Southern Maryland.

These individuals recently traveled to a location in the US that is experiencing an active measles outbreak. All Marylanders should review potential exposure sites and times, watch for symptoms, and confirm they are up to date on their measles, mumps, and rubella vaccinations.

Anyone who visited the following location during the listed date and hours might have been exposed:

• J&R Feeds LLC (28038 Thompsons Corner Road, Mechanicsville) from Thursday, July 16 – Tuesday, July 21
• MedStar Health Urgent Care in Charlotte Hall (37767 Market Drive, Suite 100, Charlotte Hall) on Monday, July 20, 2026, from 8:30am-1:15pm
• MedStar St. Mary’s Hospital Emergency Room (25500 Point Lookout Road, Leonardtown) on Tuesday, July 21, from 11am-6:45pm

Measles is a highly contagious disease that is spread easily through the air when an infectious person breathes, coughs, or sneezes. The virus can remain in the air for up to two hours after the infected person leaves the area. The disease is also spread by direct contact and by touching infected surfaces.

What to Do If You Think You May Have Been Exposed

People, especially those not fully vaccinated or otherwise immune to measles, who were at these locations during the possible exposure times should monitor themselves for any early symptoms of measles for 21 days after the potential exposure.

Exposed individuals who develop a fever or other symptoms of measles should not go to child care, school, work, or public places and should contact their healthcare provider. They should contact their healthcare provider before going to a waiting room or emergency department so that the facility can take measures to prevent measles from spreading to others.

Find out whether you have been vaccinated for measles or previously had measles. If you have received two doses of a measles-containing vaccine or were born before 1957, you are generally considered protected. To check your immunization status, contact your health care provider or securely request your records online.

If you are not fully vaccinated or otherwise immune to measles (e.g., you already had measles) and you might have been exposed, contact your healthcare provider or your local health department as soon as possible to discuss the best next steps for you, as you may qualify for post-exposure treatments.

Contact information for local health departments is available on the department website.

Early symptoms of measles are a fever of more than 101 degrees Fahrenheit, a runny nose, cough and red, watery eyes. Usually, one to four days after the early symptoms, a red rash appears on the face and spreads to the rest of the body. Symptoms typically develop 10 to 14 days after exposure but can develop as soon as seven days and as long as 21 days after exposure. A person with measles is contagious, beginning four days before the rash appears until four days after the rash begins.

Maryland has confirmed 11 measles cases in 2026, including these two. Information about past measles cases in Maryland is available on the department website
