TUESDAY MEASLES UPDATE: DPH Reports Nine New Measles Cases in Upstate, Bringing Outbreak total to 153

FOR IMMEDIATE RELEASE:
Dec. 23, 2025

COLUMBIA, S.C. ― The South Carolina Department of Public Health (DPH) is reporting 9 new cases of measles in the state since Friday, bringing the total number of cases in South Carolina related to the Upstate outbreak to 153 and the total number reported to DPH this year to 156.

Five of the new cases were known household exposures, two resulted from a previously reported school exposure, the source of one is unknown and one is still being investigated.

There are currently 249 people in quarantine and seven in isolation.

DPH encourages those potentially exposed to notify a health care provider of the exposure before seeking care to allow arrangements to be made in clinical settings to protect others as clinical sites have also been settings of public exposures.

A person with measles is contagious from four days before the rash appears through four days after its onset, meaning people with mild symptoms can spread measles before they know they have the disease. To help stop the spread of measles, it is very important for those who have even mild illness or are in quarantine to stay home to protect others. We encourage employers to support workers in following DPH recommendations to stay out of work while ill or in quarantine which also protects businesses, other workers and clients.

Vaccination continues to be the best way to prevent measles and stop this outbreak. Vaccines are also available at many primary care provider offices and pharmacies, as well as DPH Health Departments.

Any community partners or organizations interested in scheduling a vaccination event from DPH’s Mobile Health Unit can request a visit to their location by completing this form on our website. DPH will prioritize requests for MMR vaccination events, if received, and will also take steps to increase appointment availability for MMR vaccination in health department locations, should demand dictate.
