Jefferson County sits about 90 miles northeast of Pittsburgh and lost another resident to measles complications in September.

Still unverified

The Franklin County coroner's report of a measles-associated death is disputed by the Pennsylvania Department of Health, whose investigation has not found cases meeting its criteria.
