A significant measles outbreak in South Carolina has reached nearly 800 cases, surpassing the previous record set by Texas, and becoming the largest outbreak in the U.S. since measles was declared eliminated. The CDC has confirmed substantial case numbers across multiple states, indicating a troubling rise in infections as public health officials warn that the nation is on the verge of losing its measles elimination status. Schools in affected areas have reported quarantines, adding to concerns about vaccination rates and public health responses. Health experts urge immediate action to control the outbreak and protect communities.
