Measles Cases Increase in South Carolina

South Carolina’s measles outbreak has escalated, with 646 cases reported since October, primarily in Spartanburg County. Concerns are mounting that the U.S. may lose its measles elimination status, as vaccination rates have fallen below the herd immunity threshold. Health officials stress the importance of the MMR vaccine, which is 93% effective after one dose and 97% after two. As the Pan American Health Organization prepares to review elimination status in April, experts warn that the U.S. may face future outbreaks if vaccination rates do not improve.
