Two new measles cases confirmed in Maryland travelers

Two residents of Prince George's County, Maryland, have tested positive for measles after traveling together internationally. The Maryland Department of Health reported these cases on Thursday. Officials noted that these infections are unrelated to a previously confirmed case in Howard County. The cases are also not linked to the ongoing measles outbreak in parts of the southwestern United States, including New Mexico, Oklahoma, and Texas. The health department is working to identify passengers and others who may have been exposed during flights and in other locations. Possible exposure sites include Washington Dulles International Airport, Kaiser Permanente Largo Medical Center, Ronald Reagan Washington National Airport, and public transit in the Washington Metro area. Health officials urge anyone who visited these places during specified times to monitor for measles symptoms, which can appear up to 21 days after exposure. Symptoms to watch for include fever, runny nose, cough, and red, watery eyes, leading to a spreading rash. Officials recommend that anyone exposed consult their vaccination status, as post-exposure treatment may be available for those who are not immune. Maryland recorded one measles case in 2024 and another in 2023, both involving international travel. Health authorities advise residents to check their vaccination status before traveling abroad.
