ABC News reported that Lancaster County in Pennsylvania has been the epicenter of what the outlet described as the nation's worst measles outbreak in 35 years. Its headline said the outbreak has reached Pennsylvania Amish country and that more people in the area show "openness to vaccines."

ABC News placed the outbreak in Pennsylvania Amish country, and its summary identified Lancaster County as the outbreak's epicenter. The outlet's description of the outbreak as the nation's worst in 35 years rests on its own account, and the summary does not say how that comparison was measured. The framing is therefore attributed to ABC News rather than independently verified in this story.

ABC News described Lancaster County as the epicenter, but the summary does not say how many cases have been recorded there or elsewhere in the state. It also does not report case counts by date, the number of residents who have been vaccinated, or any direct comment from health officials, community members, or Amish residents. Those details are not available in the summary reviewed for this story.

The headline's claim that more people show openness to vaccines is reported by ABC News alone in the material available here. No other outlet's account was available to confirm, qualify, or contradict the outlet's description of the outbreak or of attitudes toward vaccination. ABC News published the report on October 30, 2026, according to the source data.

The full ABC News report is available at the ABC News article on the Pennsylvania Amish country measles outbreak. The author is not listed in the source data, and the details above reflect only the headline and summary of that report.
