South Carolina sees 3 new measles cases, brings statewide total to 159

COLUMBIA, S.C. (WCIV) — The South Carolina Department of Public Health reported three new cases of measles, bringing the total number of cases tied to the Upstate outbreak to 156 and the statewide total this year to 159.

Health officials said the newly reported cases stem from a previously identified exposure at a school.

As of the latest update, 252 people are in quarantine and three are in isolation. The latest quarantine period is set to end Jan. 15, according to DPH.

The agency urged anyone who may have been exposed to measles to notify a health care provider before seeking treatment so precautions can be taken to prevent further spread in clinical settings.

Measles is highly contagious and can be spread from four days before a rash appears through four days after it begins. DPH officials said people with mild symptoms may unknowingly transmit the virus before realizing they are infected. Those who are ill or in quarantine are encouraged to stay home, and DPH asked employers to support workers who follow public health guidance, noting it also helps protect businesses, coworkers and clients.

Most cases in the outbreak involve children and adolescents. Of the 156 cases linked to the Upstate outbreak, 34 are in children younger than 5, 104 are among people ages 5 to 17, and 12 are adults 18 and older. Six cases involve minors whose exact ages were not disclosed.

DPH said the vast majority of cases involve people who were not vaccinated. Of those infected, 148 were unvaccinated, three were partially vaccinated, one was fully vaccinated and four had unknown vaccination status.

Vaccination remains the most effective way to prevent measles and slow the outbreak, officials said. Measles, mumps and rubella vaccines are available at primary care offices, pharmacies and DPH health departments. Community organizations can also request vaccination events through DPH’s Mobile Health Unit, which is prioritizing MMR vaccination efforts.
