Health officials are advising of potential measles exposures after confirming a case that traveled through Washington Dulles International Airport last Saturday.
A person with measles traveled through the Dulles airport and took a shuttle bus to its rental car facilities on Saturday, Jan. 24. Health officials “are coordinating an effort to identify people who might have been exposed, including contacting potentially exposed passengers on specific flights,” the Virginia Department of Health said in a release today (Saturday).
The exact times and locations of potential exposure sites are listed below, according to VDH.
- Dulles’ Concourse B, on transportation to the International Arrivals Building (IAB) and in the baggage claim area between 5-9 a.m.
- Dulles shuttle bus to the rental car facilities between 7-9:30 a.m.
The patient was a resident from out-of-state, VDH said, and additional details will not be disclosed to protect the patient’s privacy.
This is the fourth case of measles reported in Virginia in 2026 — nearing the total of five cases reported by VDH in 2025.
Earlier this month, potential exposures from a preschool-age patient were reported at health care facilities in Woodbridge and Fairfax County, while another case from a preschool-age patient was reported at Fort Belvoir Medical Center, Baltimore/Washington International Airport and on a regional Amtrak train.
Anyone who was at Dulles’ potential exposure sites at times reported is encouraged to report the exposure to the Loudon County Health Department and check their vaccination status.
Exposed people 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.
“People who are not fully vaccinated or otherwise immune to measles should contact their healthcare provider or call their local health department promptly to discuss any questions they might have,” VDH said.
The most likely time for patients to become sick from the exposure would be Jan. 31 through Feb. 14, according to VDH. Patients are advised to watch for symptoms at least 21 days post-exposure.
