New potential measles exposures in Northern Virginia were confirmed last week, following several cases in the region so far this year.
A preschool-age child and an out-of-state resident with measles recently traveled in Reagan National Airport and a Yellow Line Metro train, in addition to visiting a medical facility in Haymarket. Dates, times and exact locations of the potential exposure sites are listed below, according to the Virginia Department of Health.
- Ronald Reagan Washington National Airport, Terminal 2, 2401 Smith Blvd in Arlington, between 12:30-10:30 p.m. Monday, Jan. 26
- Washington Area Metro on Monday, Jan. 26:
- Yellow Line Train from Ronald Reagan Washington National Airport station transferring at the Gallery Place – Chinatown station to the Red Line Train heading towards the Glenmont station between 8:30-11:30 p.m.
- Heathcote Health Center, 15195 Heathcote Blvd. in Haymarket between 1:15-4:15 p.m. Thursday, Jan. 29.
People who were exposed are instructed to fill out a VDH reporting survey, according to the Alexandria Health Department. Exposed people are also encouraged to check their vaccination status.
Patients who have received two doses of a measles-containing vaccine or were born before 1957 are “considered protected” and do not need to seek treatment, according to VDH, while immunocompromised patients should contact a doctor or local health department for specific advice.
Over the next few weeks, those who were exposed, born after 1957 and are not fully vaccinated are instructed to watch for symptoms for 21 days post-exposure. Symptoms include a fever over 101 degrees, coughing, a rash and red, watery eyes.
These cases bring Virginia’s 2026 measles case count to six, surpassing the state’s five reported cases in 2025.
Five of the six cases this year have been reported in Northern Virginia, and five have occurred in preschool-age children, from infants to four years old.
