Published on Mar. 7, 2026

South Carolina has reported one additional measles case, bringing the total to 991 as the state's outbreak, the nation's largest in decades, shows signs of slowing. The state has seen a 70% increase in vaccination in February compared to the same month last year, and the CDC is sending additional experts to help analyze data and contain the outbreak.

Why it matters

The measles outbreak in South Carolina has been one of the largest in the U.S. in recent years, raising concerns about the spread of the highly contagious virus and the importance of vaccination. The state's efforts to increase vaccination rates and contain the outbreak are critical to protecting public health.

The details

According to the latest data, at least 52 people are in quarantine after being exposed to the virus, and another three are in isolation. Of those infected, 925 were unvaccinated, 19 were partially vaccinated, 26 were fully vaccinated, and 21 had unknown vaccination status. The outbreak has been centered in the northwest part of the state, including Greenville and Spartanburg, where there was a 139% increase in measles vaccinations last month compared to February 2025.

  • On March 6, 2026, the state reported one additional measles case, bringing the total to 991.
  • In February 2026, the state saw a 70% increase in vaccination compared to the same month last year.
  • Next week, three CDC 'disease detectives' from the agency's Epidemic Intelligence Service are expected to arrive in the state to help analyze data.
