Health officials in Maryland and Virginia have issued alerts following a confirmed measles case in an individual who traveled through both states while infectious.

Maryland Exposure Sites
The Maryland Department of Health (MDH) identified several potential exposure locations from January 7-8:

  • Amtrak Northeast Regional train from Philadelphia’s 30th Street Station to D.C.’s Union Station (9 p.m. to 11:30 p.m. on Jan. 7).
  • Amtrak’s BWI Marshall Airport shuttle bus between BWI Marshall train station and airport lower-level drop-off points (10:45 p.m. on Jan. 7 to 1:30 a.m. on Jan. 8).
  • BWI Marshall Airport parking shuttle bus between airport lower levels and long-term parking lots (11 p.m. on Jan. 7 to 2 a.m. on Jan. 8).

MDH clarified that no exposures were identified within the BWI Marshall Airport terminals, and individuals not present at these specific locations and times were not exposed in Maryland. Information on additional exposure sites in other states will be provided by those respective states.

Virginia Exposure Sites
The Virginia Department of Health (VDH) identified the Alexander T. Augusta Military Medical Center Emergency Department and Executive Medicine Suite in Fort Belvoir as a potential exposure site on Friday, from 9:30 a.m. to 3 p.m. and 10 p.m. to midnight.

VDH described the patient as a preschool-aged child with recent international travel, marking Virginia's second measles case of the year.

Guidance for Potential Exposure
Individuals who believe they may have been exposed should:

  • Verify their measles vaccination status or history of having had measles. Two doses of the measles vaccine, or birth before 1957, generally indicate protection.
  • Contact their healthcare provider or local health department if not fully vaccinated or immune and potentially exposed.
  • Monitor for measles symptoms for 21 days post-exposure. Symptoms include runny nose, cough, red and watery eyes, and a fever exceeding 101 degrees.
  • If symptoms develop, stay home and contact a healthcare facility before arriving to prevent further spread.
