Measles Outbreak: South Carolina Faces Nation’s Largest Surge in Decades
South Carolina is grappling with a significant measles outbreak, currently the largest in the United States in over three decades. As of February 13, 2026, the state has reported 950 cases, primarily centered in Spartanburg County, with the first case identified in October 2025 . Health officials are urging parents to ensure their children are up-to-date on their measles, mumps, and rubella (MMR) vaccinations as the highly contagious virus spreads.
Understanding the Threat of Measles
Measles is a highly contagious respiratory disease that can spread through the air when an infected person coughs or sneezes. The virus can remain infectious in the air for up to two hours after the infected person has left the area . A person is contagious four days before and after a rash develops, meaning individuals can unknowingly transmit the virus before exhibiting symptoms.
Symptoms and Potential Complications
Initial symptoms of measles can resemble a common cold, including a cough, fever, and red, watery eyes. However, measles can lead to more severe complications, such as pneumonia and encephalitis (swelling of the brain) . In rare cases, measles can likewise cause deafness, intellectual disability, and even death.
Vaccination: The Best Defense
The Centers for Disease Control and Prevention (CDC) and the South Carolina Department of Health (DPH) emphasize that vaccination is the most effective way to protect against measles . The MMR vaccine is typically administered in two doses: the first between 12 and 15 months of age, and the second between 4 and 6 years of age. Children as young as six months can receive a dose if they are exposed to an outbreak region, such as the current situation in South Carolina.
Current Outbreak Statistics
As of February 12, 2026, the CDC has reported 910 confirmed measles cases nationwide in 2026, with outbreaks occurring in 24 jurisdictions . The South Carolina outbreak accounts for a significant portion of these cases. In 2025, a total of 2,280 confirmed measles cases were reported across the United States .
Addressing Vaccine Hesitancy
Health officials have noted an increase in vaccine hesitancy in recent years, fueled by misinformation and distrust. They urge parents to consult with trusted healthcare providers for accurate, science-based information about the safety and efficacy of the MMR vaccine. The American Academy of Pediatrics offers reliable resources on measles vaccination .
What to Do If You Suspect Exposure
If you believe you or your child may have been exposed to measles, it is crucial to call your healthcare provider before visiting. This allows them to take necessary precautions to prevent further spread of the virus.
Updates and Resources
The South Carolina DPH will continue to provide updates on the measles outbreak twice a week, on Tuesdays and Fridays at 1 p.m. . For more information, please visit the DPH website or the CDC’s measles page.
