Story summary

As of October 17, 2026, the Centers for Disease Control and Prevention (CDC) is sending a "disease detective" from its Epidemic Intelligence Service to Pennsylvania to help address a growing measles outbreak. The CDC's decision comes after 4,410 cases were reported nationwide, with 1,222 cases in Pennsylvania alone, including six confirmed measles-associated deaths. Since August, the dispute between Health Secretary Robert F. Kennedy Jr. and Pennsylvania Governor Josh Shapiro over vaccine misinformation has escalated, leading to increased public health concerns. The CDC is providing additional support through the Epi-Aid program, which offers rapid field investigations for urgent public health issues. This assistance includes deploying a specialist and releasing nearly $4 million in aid specifically for measles response efforts in Pennsylvania.
