Pennsylvania reported more than 1,000 confirmed measles cases and at least five deaths by October 6, 2026, mostly among the unvaccinated. Franklin County has since announced a sixth measles-associated death, an unvaccinated 39-year-old woman. The state has confirmed five deaths while the CDC has acknowledged only two, and the CDC did not publish the four deaths reported by Pennsylvania. Two-thirds of cases and two of the four deaths are adults. One estimate puts the true case count near three times the 1,260 reported, perhaps 5,000 to 6,000. Nationally, measles cases rose 8 percent in one week to 4,410, and the White House has ordered the MMR vaccine split into separate shots.
