Measles symptoms can take days or weeks to appear after exposure, making it important to know what to watch for.
The Pennsylvania Department of Health says symptoms can develop 7 to 21 days after exposure and typically begin with fever, cough, runny nose and red, watery eyes. A rash generally develops several days later, starting on the head and spreading down the body.
Measles can spread before that telltale rash appears, and Pennsylvania health officials say the virus can remain infectious in the air and on surfaces for up to two hours after an infected person leaves.
What should you do if you’ve been exposed to measles?
The Centers for Disease Control and Prevention advises people who believe they or their child have been exposed to measles to call their health care provider immediately.
Pennsylvanians who were exposed and are experiencing symptoms can also call 877-PA-HEALTH (877-724-3258) for guidance. This video explains what Pennsylvania residents should know and do.
