Pennsylvania recorded 460 confirmed measles cases across 31 counties according to data released by the Pennsylvania Department of Health (DOH). State health officials report that nearly 20 percent of infected individuals require hospitalization, with 83 hospitalizations and two measles-associated deaths officially documented during the ongoing transmission.
Outbreak Scope and Public Exposure Sites
The virus has maintained a steady spread across dozens of Pennsylvania communities, prompting public health alerts. According to DOH tracking, the outbreak spans 31 counties, with new positive cases continuing to emerge. Complementary reporting from the Pennsylvania Department of Health highlights an out-of-state individual contagious with measles who visited public locations across Adams, Clearfield, Lancaster, and York counties, creating exposure risks at sites such as the Sapp Bros. Travel Center in Clearfield and the Farmhouse Restaurant at the Barn Resort in Gettysburg.

State data indicates that the virus spreads when an infected person breathes, coughs, or sneezes. According to health officials, the pathogen remains infectious in the air and on surfaces for up to two hours after an infected individual leaves a space. Initial symptoms typically include fever, cough, runny nose, and red, watery eyes, followed by a rash that starts on the head and spreads downward.
Vaccination Rates and Clinical Guidance
State officials emphasize that immunization remains the primary defense against the virus. According to the DOH, the measles, mumps, and rubella (MMR) vaccine is administered in a two-dose series and provides 97 percent protection after completion. Concurrently, data cited by CBS News indicates that kindergarten vaccination rates statewide and nationally have fallen below the 95 percent threshold required for community herd immunity.

Pro Tip: Residents who suspect they may have been exposed should monitor for symptoms for up to 21 days and contact a healthcare provider or the DOH toll-free hotline at 877-PA-HEALTH (877-724-3258) before visiting a medical facility, in order to prevent further community exposure.
