Pennsylvania has surpassed 1,000 confirmed measles cases this year, marking its largest outbreak since the early 1990s. The state's health department reported 1,004 cases as of Monday, with five deaths and 198 hospitalizations. Lancaster County is most affected, with 391 cases linked to sizable Amish and Mennonite populations. This surge comes amid a broader US measles resurgence; the CDC has recorded 3,887 confirmed cases this year nationwide. Pennsylvania’s governor, Josh Shapiro, expanded vaccine access in response but faces disputes over case classification with Health Secretary Robert F Kennedy Jr., who questions direct causality of reported fatalities.

Story summary
Pennsylvania is experiencing its largest measles outbreak in over three decades, surpassing 1,000 confirmed cases, including 198 hospitalizations and five deaths. The outbreak began in April and has primarily affected areas west of Philadelphia, with Lancaster County, home to significant Amish populations, recording the highest number at 391 cases. Health officials are concerned about low vaccination rates among these communities, which historically have lower uptake of MMR vaccines due to religious beliefs. With only seven out of 67 counties in Pennsylvania having their own health departments, coordinating a response has been challenging. The outbreak is drawing national attention and debates over public health policies, including criticism directed at U.S. Health Secretary Robert F. Kennedy Jr., who has previously raised concerns about vaccine safety.
