Measles Outbreak Continues in Pennsylvania
Developing
In Short: Pennsylvania's measles outbreak has worsened, with 86 new cases this week, bringing the total to 460 and causing 83 hospitalizations, as the state reports two deaths associated with the outbreak.
Pennsylvania continues to see a significant rise in its measles outbreak, with 86 new cases added this week, bringing the total number of cases to 460, with 83 hospitalizations, according to an update of the state’s measles dashboard.
The outbreak has taken a tragic turn, with the commonwealth announcing two measles-associated deaths on August 25. The Pennsylvania Department of Health initially offered limited information to protect patient privacy, but the high mortality rate of one per 200 cases suggests the outbreak is more severe than initially reported.
While the outbreak in Utah, which had the largest measles outbreak, has been contained for the third consecutive week, other states are reporting new cases. As of August 20, 2026, the CDC reported 2,777 cases in 47 states.
The CDC typically updates its measles numbers on Friday, but a notification stated that the August 28, 2026, data have been delayed and will be updated as soon as possible.
