Measles Cases Rise in South Carolina and Michigan as U.S. Total Reaches 1,563
COLUMBIA, S.C. — Health officials have confirmed additional measles cases in South Carolina and Michigan, bringing the total number of infections in the United States this year to 1,563, according to data published by the Center for Infectious Disease Research and Policy (CIDRAP). The growing number marks one of the largest nationwide outbreaks in recent years, underscoring concerns about falling vaccination rates and regional clusters of unvaccinated populations.
New Infections Reported Across States
Public health departments in both South Carolina and Michigan reported new laboratory-confirmed cases this week, expanding a pattern of spread that has affected more than two dozen states since early 2025.
State officials say the cases involve individuals who were unvaccinated or partially vaccinated, consistent with national trends showing that most recent infections have occurred among people lacking full immunity.
The South Carolina Department of Health and Environmental Control (DHEC) confirmed that its latest case was detected in the Upstate region, with contact tracing underway. “We are working to notify anyone who may have been exposed and are urging residents to verify their vaccination status,” DHEC officials said in a statement.
Experts Warn of Outbreak Risks
Epidemiologists warn that measles remains highly contagious, with one infected person capable of spreading the virus to 90% of nearby unvaccinated individuals. The Centers for Disease Control and Prevention (CDC) continues to emphasize the importance of the MMR vaccine, which provides strong protection against both measles and mumps.
“Even a few cases in one area can quickly escalate into larger outbreaks,” said Dr. Emily Santos, an infectious disease specialist at Emory University. “This year’s numbers are a reminder that gaps in vaccination coverage put entire communities at risk.”
Low Vaccination Rates Fueling Spread
National data show that childhood MMR vaccination coverage has declined to just over 90%, below the threshold needed to prevent community transmission. Experts say misinformation and vaccine hesitancy have contributed to the decline, especially in rural areas and among certain religious communities.
South Carolina health officials are calling on parents to review their children’s immunization records ahead of the upcoming winter season, when respiratory viruses are most active. “Measles spreads quickly through coughing and sneezing,” a DHEC spokesperson said. “Vaccination remains our best defense.”
Public Health Guidance
Residents are urged to watch for classic measles symptoms, which typically appear 7–14 days after exposure. They include:
- High fever
- Cough and runny nose
- Red, watery eyes
- A distinct rash that starts on the face and spreads across the body
Anyone who suspects exposure or symptoms should call their healthcare provider before visiting in person to prevent further spread.
