US measles cases cross 5,000, highest since 1991

The US CDC confirmed 5,182 measles infections, the highest since 1991, spanning 45 states. At least eight deaths have been reported this year. The US risks losing its measles-eliminated status next week as PAHO reviews transmission data. Falling vaccination rates have driven the decades-worst outbreak, with Pennsylvania the hardest-hit state at 1,467 cases.
