Additionally, Butler County recorded its initial case this week. That news came Tuesday, the same day the Department of Health announced that two people from Lancaster County have died from the virus. Those were the first two measles deaths in Pennsylvania in 35 years.

Last week, for the first time since 2019, a person tested positive for measles in Allegheny County. The unidentified person was an unvaccinated patient at UPMC Children’s Hospital in Lawrenceville who is not a county resident.
