Pennsylvania surpasses 900 measles cases

The measles outbreak plaguing the U.S. appears to be getting worse in Pennsylvania. State health officials are now reporting 903 cases of the virus across 39 counties — an increase of over a dozen more cases since Friday. Officials, however, say less than 1% of those cases — only four people — are among those who are fully vaccinated. So far this year, there have been four measles-related deaths across the commonwealth, all of them among unvaccinated individuals. State officials are urging people to get the MMR vaccine, which gives 97% lifetime protection against measles after two doses. More than 7,900 doses have been given this year. Symptoms of the virus include fever, cough and runny nose, followed by a rash that starts on the head and spreads down. Anyone exposed to the virus and showing symptoms is advised to call their doctor. (Photo credit: CDC via Getty Images)
