A measles case has Maryland health officials on high alert after an infected person traveled on an Amtrak train from Philly to DC and used BWI Airport shuttles between Jan 7-9. If you were on those trains or shuttles during those times, you might’ve been exposed. No cases inside the airport terminals, but still—measles spreads fast! Check if you were in those spots and keep an eye out for symptoms. Wild how one trip can set off a health scare! #News #MeaslesAlert #Maryland
