Measles Outbreak: Amish Community at Center
30 Oct
Summary
- Lancaster County, PA, is the epicenter of the worst US measles outbreak in 35 years.
- Overall measles vaccination rates are falling in the general public and remain low among the Amish.
- The outbreak highlights the interconnectedness of Plain and 'English' communities in health crises.
Lancaster County, Pennsylvania, a region with the largest Amish population in the U.S., is currently experiencing the nation's most severe measles outbreak in 35 years. This situation arises as vaccination rates for the general public decline, while rates have historically remained low among the Amish and other conservative "Plain" communities.
The contagious measles virus, officially considered eliminated from the U.S. since 2000, is spreading due to these intersecting factors. Pennsylvania leads the nation in cases, with a significant portion occurring in Lancaster County, though official figures may be an undercount.
While attitudes toward vaccines vary, "Plain" communities overall are less vaccinated due to cultural habits rather than religious doctrine. However, a growing openness to vaccination is now being observed in some members of these communities, alongside increased precautions taken by the wider public.
The outbreak underscores the deep interconnectedness between "Plain" and "English" populations. Interactions in markets, businesses, and daily life mean that neither group is truly separate, emphasizing shared health risks and the need for collective action.
As of late October 2026, Pennsylvania's measles rates have decreased from their September peak, but health experts anticipate a potential rise with winter gatherings. Measles, though often mild, can lead to severe complications, including pneumonia and encephalitis, and even death.
Efforts are underway to increase vaccination rates through targeted outreach clinics, some offering earlier-than-usual infant vaccinations. These initiatives aim to mitigate the spread by protecting vulnerable populations and fostering trust within communities where building rapport can take years.
Declining childhood vaccination rates are not exclusive to "Plain" communities; they are a broader trend across central Pennsylvania since 2020. This decline has eroded herd immunity, making the population more susceptible to outbreaks and highlighting the need for renewed public health focus on widespread immunization.
