South Carolina Measles Outbreak Becomes Largest In U.S. History Since First Elimination
The outbreak has caused nearly 800 cases mainly among unvaccinated children in Spartanburg County, with over 600 cases added in 2026 alone, health officials said.
- On Tuesday, the South Carolina Department of Public Health reported 789 measles cases, marking the largest U.S. outbreak since elimination was declared in 2000.
- Health officials say 93% of patients were unvaccinated, fueling rapid transmission, while Dr. Deborah Greenhouse warned under-immunized Spartanburg County school communities created a "tinder box" for measles spread.
- DPH identified exposures at Dorman High School, Inman Intermediate, and New Prospect Elementary, with 557 people in quarantine, 20 in isolation, and 18 hospitalized since the outbreak began.
- In neighboring states, North Carolina reported 14 cases as of Tuesday, some linked to South Carolina, while Union County quarantined more than 170 people connected to Shining Light Baptist Academy.
- Public-Health experts warn the U.S. risks losing measles elimination status after reporting more than 2,200 cases in 2025 and stress a 95% vaccination threshold is needed.
