South Carolina officials have declared the end of the largest measles outbreak in the U.S. since 1991, following 42 days without new cases. The outbreak, which began last October, infected 997 individuals—primarily unvaccinated children—and resulted in at least 21 hospitalizations. Public health measures, including increased vaccination efforts, were credited for controlling the outbreak, though concerns remain due to pockets of low immunity in the community. The CDC reports over 20 new outbreaks across the U.S. this year, highlighting a national decline in vaccination rates that poses ongoing risks for future outbreaks.
