Two infected people may have exposed others at a soccer camp at Millersville University on Aug. 4-5 and at a Whole Foods in Manheim Township on Aug. 12, the Pennsylvania Department of Health said.
Health officials are contacting camp participants, including some current students and staff who assisted them, while Whole Foods said it is cooperating and urged anyone with symptoms to contact a provider or the state.
Unvaccinated people face the highest risk, and the department said every confirmed Pennsylvania measles case in 2026 involved someone not fully vaccinated; two vaccine doses are 97% effective.
Lancaster County has recorded 167 cases this year, including 51 in the past two weeks, helping drive Pennsylvania's total to 340 and the U.S. count to 2,566 — the highest this century.
