“This is predominantly more from families, whole families getting it, and because they’re not staying home,” said Jeanne Franklin, director of the Chester County Health Department.’
Franklin said all of the county’s confirmed measles cases involve people who were not vaccinated against the virus.
“The most important thing is that if individuals know others who have been exposed to measles or actually have measles to stay away from them so they don’t contract it. Those who have been told who have measles please let their family, friends and neighbors know so they have a chance to make a decision about what they’re going to do. To isolate or get vaccinated, ” Franklin said.

“I’m glad I got my daughter inoculated. It is worrisome because of course it is a highly contagious disease and really trusted what science has told me and I’ve got my daughter vaccinated, and no negative effects. I am vaccinated and that’s over 30 years ago. I am sorry to hear others are going through this,” one resident said.
