South Carolina Measles Outbreak: Trends and What to Expect
The measles outbreak in South Carolina’s Upstate region continues, but recent data suggests a potential slowing of new cases. As of February 17, 2026, the state has confirmed 962 cases, a significant number, but a decrease from the 201 cases reported the week of January 11th. The week of February 1st saw 71 new cases.
Understanding the Current Situation
The South Carolina Department of Public Health (DPH) is actively monitoring the situation and has identified public exposure locations, including Libertas Academy and a Walmart in Powdersville, Greenville. Potential exposure at the Walmart occurred on February 8th between 4 p.m. And 8 p.m., and individuals who were present, especially those without immunity, should monitor for symptoms through March 1st.
The Importance of Vaccination
The measles, mumps, and rubella (MMR) vaccine remains the most effective defense against the virus. According to the U.S. Centers for Disease Control and Prevention, the MMR vaccine is 97% effective against measles with two doses. The standard vaccination schedule involves doses between 12-15 months and 4-6 years of age.
Even those previously exposed can benefit from vaccination. Currently, 893 of the 962 cases are among unvaccinated individuals, 20 are partially vaccinated, and 26 are fully vaccinated with two doses of the MMR vaccine. Twenty-three cases have unknown vaccination status.
Measles Symptoms and Risks
Measles is highly contagious and can spread through the air for up to two hours. Symptoms include a high fever (potentially exceeding 104 degrees), cough, runny nose, red, watery eyes, and tiny white spots inside the mouth (Koplik Spots). A red, raised rash typically follows, starting on the face and spreading to the rest of the body.
The virus can lead to serious complications affecting the brain, blood cells, and pregnancies, and can even be fatal. Since the beginning of the outbreak, 20 hospitalizations have been reported due to measles complications, with additional cases requiring medical care without hospitalization.
Upcoming Vaccination Clinic
To address the outbreak, DPH will host a free MMR vaccination clinic on March 3rd, from 10 a.m. To 2 p.m. At Grace Community Church in Spartanburg.
What Does the Future Hold?
While the recent decline in weekly cases is encouraging, the outbreak is not yet contained. Continued vigilance and increased vaccination rates are crucial. The 127 people currently in quarantine, with quarantines ending as late as March 11th, indicate ongoing transmission. The effectiveness of the upcoming vaccination clinic will be a key factor in determining future trends.
The DPH is also monitoring for complications, though these are not reportable, highlighting the potential for long-term health impacts even beyond confirmed cases.
