Measles Outbreak Reaches Clemson University as South Carolina Cases Surge
A rapidly escalating measles outbreak in South Carolina has now impacted a major university campus, with health officials confirming a case linked to Clemson University. The development raises concerns as the state grapples with a significant increase in infections, particularly among young people.
The South Carolina Department of Public Health (DPH) notified Clemson University of the diagnosis of an individual affiliated with the school who tested positive for the highly contagious virus. University officials stated that the individual is currently isolated in accordance with DPH guidelines, and a thorough contact tracing effort is underway.
“DPH is conducting contact tracing with individuals who may have been exposed and outlining isolation and quarantine protocols,” the university said in a statement released Tuesday. “DPH will provide email notifications to any individuals identified as possible contacts who may need to quarantine.”
Located approximately 120 miles east of Atlanta, Clemson University serves a student population of around 30,000. This confirmed case arrives shortly after state health officials issued warnings about the worsening outbreak.
As of Tuesday, January 20, 2026, a total of 646 measles cases have been reported across South Carolina since the outbreak began last fall. Alarmingly, 88 new cases were confirmed just since Friday, according to the DPH. Currently, 34 Clemson students and 50 students at nearby Anderson University, located a half-hour south, are under quarantine.
The speed of the outbreak’s growth is particularly concerning. “Over the last seven to nine days, we’ve had upwards of over 200 new cases. That’s doubled just in the last week,” explained a physician specializing in emergency medicine at Prisma Health in Greenville, South Carolina.
Health officials report that eight people have been hospitalized due to measles complications, though the number currently hospitalized remains unclear. Approximately 200 people are currently infected, according to a pediatric infectious disease specialist at Prisma Health, but the actual number could be higher due to the virus’s ability to spread for up to four days before symptoms manifest.
The highly contagious nature of measles – with each infected person capable of transmitting the virus to as many as a dozen others – presents a significant challenge to containment efforts. A disproportionate number of cases in South Carolina have been reported among children and teenagers, and state officials emphasize that the majority of those infected were not vaccinated.
Measles typically begins with a fever, followed by a distinctive red, blotchy rash that originates on the head and spreads downward. While most individuals recover, the illness can lead to serious complications and, in some instances, can be fatal.
Nationwide, the U.S. Centers for Disease Control and Prevention (CDC) reported 2,242 measles cases last year, including three deaths. The CDC data reveals that nearly all cases occurred in individuals under the age of 20, and a staggering 93% of those affected were either unvaccinated or had an unknown vaccination status.
