Pennsylvania health officials are warning people that they could have been exposed to measles after an infected party visited a children’s museum in Philadelphia last week.
ABC World News reported that the Pennsylvania Health Department said the possible exposure occurred at the Please Touch Museum on Monday between 3:30 and 5 p.m.
Officials also said that the same person visited a CVS Pharmacy in a suburb outside of the city on Sunday evening.
Measles are highly contagious and can remain viable on surfaces for a bit of time.
"Infected droplets and secretions can remain contagious on surfaces for up to two hours," the health department said in a statement.
Symptoms of a cough, high fever, runny nose and characteristic rash usually begin within one to two weeks. Other complications associated with the disease include diarrhea, pneumonia, inflammation of the brain and even death.
NBC 10 noted that the MMR vaccine protects against the disease, however, children under a year old are too young to be vaccinated and are at risk.
The Centers for Disease Control and Prevention said that there were more than 600 confirmed cases of measles in 24 states last year. Pennsylvania accounted for just three of those cases.
