Vaccine hesitancy fed by misinformation is causing new surges of measles and whooping cough, while COVID-19 hotspots persist in some states and a new threat looms from an Ebola outbreak in central Africa. Nationally there have been 1,983 measles cases this year, nearly the 2,288 total for all of 2025, which in itself was the worst year since 1991, the federal Centers for Disease Control and Prevention reported Friday. Halfway through the year, 12 states and the District of Columbia already have more measles cases than they did for a full year in 2025. That's true for South Carolina and Utah, where cases are already more than double last year, and also for states such as Florida, which has 139 cases so far compared with eight in 2025, and Virginia, which already has 63 compared with six in all of 2025.
