US Measles Cases Reach 33-Year High Amid Outbreak Spread

South Carolina is currently facing a measles outbreak with eight confirmed cases in the northern part of the state, all among unvaccinated individuals, according to the South Carolina Department of Public Health (DPH). Dr. Linda Bell, the state's epidemiologist, noted that the source of infection for two cases remains unidentified, and the department expects more cases to be reported. Measles is highly contagious, spreading through airborne transmission and can be infectious for days before symptoms like a distinctive rash appear. Nationwide, the U.S. has witnessed a surge in measles cases, reaching 1,544 confirmed infections in 2025 — the highest since 1992 — largely due to declining vaccination rates among children. The Centers for Disease Control and Prevention (CDC) emphasize that vaccination, particularly the two-dose measles-mumps-rubella (MMR) vaccine recommended for children, is 97% effective in preventing infection and critical to controlling outbreaks. Public health officials urge individuals to ensure their immunizations are up to date and to avoid contact with others if symptomatic to prevent further spread.
