Health Department Urges Residents to Check Exposure After Measles Case

The Maryland Department of Health has issued a public notification regarding a potential measles exposure after confirming a case in a Washington, D.C. resident who visited a location in Maryland while infectious on April 24, 2026. Health officials say there is no known connection between this case and other measles cases reported in Maryland this year.

According to officials, individuals who were at the New Hampshire Business Center, 6495 New Hampshire Ave. in Hyattsville, between 12 pm and 6:30 pm on April 24 may have been exposed. Measles is a highly contagious virus that spreads through the air when an infected person coughs or sneezes and can linger in the air for up to two hours. Health officials are urging anyone who may have been exposed to review their vaccination status and monitor for symptoms for up to 21 days.

Early symptoms include fever over 101°F, cough, runny nose, and red, watery eyes, followed by a rash that typically appears one to four days later and spreads across the body. Individuals who develop symptoms are advised to stay home and contact their healthcare provider before seeking in-person care to prevent further spread. Health officials emphasize that vaccination remains the most effective protection against measles and recommend that eligible individuals ensure they are up to date on the MMR vaccine.
