Pennsylvania health officials reported a fifth measles-associated death this week, an unvaccinated Lancaster County resident whose identity was not released. The state’s outbreak has grown to 943 confirmed cases across 39 counties, with about 176 hospitalizations, according to state data. Officials say 40 to 119 new infections were logged in the most recent week, depending on the reporting period cited. The CDC has confirmed two national measles deaths in 2026, a lower count than Pennsylvania’s own tally. Public health officials describe the outbreak as the largest and fastest-growing in the country and say it is part of the worst national measles year since 1991. One outlet reported that local investigators in Lancaster County have not confirmed the fifth death.
