Pennsylvania has recorded 1,078 measles cases this year, with 207 hospitalizations and five deaths, state health officials reported Wednesday.

Why it matters: It is the worst U.S. measles year in decades, with nearly 4,000 cases nationally, and Pennsylvania alone now accounts for about a quarter of them.

Data as of Pennsylvania health officials October 7, 2026, reported via Ars Technica; CDC national figure as of October 1. Reported via The Hill.

Latest

State health officials reported Wednesday that Pennsylvania’s 2026 measles tally has reached 1,078, with 1,066 of those linked to the outbreak that began in April. Hospitalizations rose to 207 and the five deaths are now detailed: a newborn, a 6-week-old infant, an 18-year-old, a 20-year-old and a 40-year-old, all unvaccinated, with the two infants too young to have received the vaccine. The state logged 145 cases in the last seven days, and officials say the outbreak does not appear close to ending.

Earlier

Pennsylvania’s measles outbreak has passed 1,000 confirmed cases, with the state health department’s dashboard recording 1,004 cases, 198 hospitalizations and five deaths as of Monday. About a third of cases have occurred in people under 18, and the state’s kindergarten MMR coverage sits at 92.7 percent, below the 95 percent threshold for herd immunity.

The national picture is worse than it has been in decades: the CDC counted nearly 4,000 measles cases across the country as of October 1, the highest total since the early 1990s, with Pennsylvania running hundreds of cases ahead of South Carolina, the second-hardest-hit state.
