A confirmed case of measles has been reported in a patient who was at Meadville Medical Center's emergency department Tuesday.

There is no longer any risk of infection in the emergency department, but anyone who was in the vicinity of that department and the nearby entrance on May 28 between 10:30 a.m. and 1 p.m. could be at risk of possible exposure, according to Meadville Medical Center.

“Meadville Medical Center is in the process of notifying patients who may have been in that area of the building; however, if you have been properly immunized against measles, your risk of getting the disease is minimal," said Pennsylvania Secretary of Health Dr. Rachel Levine.

Measles is a highly contagious but vaccine-preventable disease that spreads through coughing, sneezing or other contact with the mucus or saliva of an infected person. Symptoms, which include fever, rash, cough, runny nose, inflamed eyes, or tiny white spots inside the mouth, typically appear 1 to 3 weeks after exposure.

People who received the Measles, Mumps and Rubella vaccination should be safe from exposure. However, some may be at risk if they were vaccinated with an inactivated vaccine, which was used from 1963 through 1967, and have not been revaccinated; or if they were born after 1957 and have only received one dose of MMR vaccine.

Those at greatest risk of contracting measles are people who have not been vaccinated, children younger than 5 years of age, pregnant women and people with compromised immune systems, according to the Centers for Disease Prevention and Control (CDC).

Anyone who has measles symptoms and was near the emergency department or the nearby entrance Tuesday is advised to contact their health provider or the Pennsylvania Department of Health at 1-877-PA-HEALTH.
