Measles outbreak grows in Pennsylvania, nearing 1,000 cases

Coverage spectrum

Covered by 3 outlets, mostly left-leaning (67%).

Pennsylvania's measles outbreak continues to expand, with the state Department of Health reporting 977 confirmed cases across 39 counties as of early October 2026, up from 943 cases reported days earlier. The state has recorded five measles-associated deaths this year, according to health officials. Lancaster County, which lacks its own health department, has reported the highest number of cases, with 381 confirmed, largely concentrated in Amish and similar religious communities that have historically low vaccination rates. Public health officials have expressed concern that the outbreak could spread further, citing gaps in county-level health infrastructure and low MMR vaccine uptake in some communities. The outbreak has also been linked to broader concerns about vaccine skepticism in the US.
