Update: Two New Measles Cases Confirmed in Prince George’s County

State officials have confirmed two new cases of measles in Prince George’s County. According to the Maryland Department of Health, both individuals recently returned from international travel together. These cases are not linked to the recent case in Howard County or outbreaks in West Texas, New Mexico, and Oklahoma.

Health officials are now working to track potential exposures. If you were in any of the following locations, you may have been exposed:

Washington Dulles International Airport – Concourse A, International Arrivals transportation & baggage claim (March 5, 8 a.m.–12:30 p.m.)
Kaiser Permanente Largo Medical Center (1221 Mercantile Ln, Upper Marlboro)

• March 5 (7:30 p.m.–March 6, 4:30 a.m.)

Passport Toyota (5001 Auth Way, Suitland, March 17, 10 a.m.–1:30 p.m.)

Stay Vigilant

Dr. Ashanti Woods of Mercy Medical Center warns: If you’re unvaccinated, your risk of contracting measles is around 95%. Symptoms can appear anywhere from 7 to 21 days after exposure—meaning people may spread the virus before realizing they’re sick.

“The rash doesn’t show up until four or five days after early symptoms. It starts at the forehead and works its way down—a deep, intense red,” Dr. Woods explains. “But by the time the rash appears, you’ve already been contagious for days.”

Take care, Baltimore. Stay safe.
