The US is experiencing a measles outbreak with 1,024 cases confirmed across 30 states, nearing 2019 levels. The CDC reports that 96% of cases involve unvaccinated individuals or those with unknown vaccination status. Hospitalization rates are at 13%, mainly affecting those under 19. Experts emphasize the vaccine's high effectiveness and the importance of two doses for near-total protection. Declining vaccination rates are contributing to the resurgence.
