The South Carolina Department of Public Health (DPH) reported 58 new measles cases in its last update of January. The case total in the Upstate measles outbreak now sits at 847, and 671 of the cases were reported in January alone.
South Carolina's Tuesday, Jan. 27 update pushed the state past a 2025 West Texas outbreak for the country's largest measles outbreak in the last 26 years.
As more people contract the disease, DPH continues its vaccination messaging. The public health agency has said in its biweekly updates that vaccination is the "best way to prevent measles and stop this outbreak."
Cases still remain concentrated in Spartanburg County; Spartanburg County is home to 813 of 847, or almost 96%, of reported cases, according to the state's measles dashboard. Greenville, Anderson and Cherokee counties were the only other counties with reported cases, which stayed consistent with Tuesday's update.
In Greenville, 28 residents have contracted the disease. Five people who live in Anderson County have contracted the disease, and less than five people who live in Cherokee County have been infected.
DPH confirmed measles exposure at just one more school — Lyman Elementary in Spartanburg School District Five. In total, 13 schools have students set to quarantine until Feb. 24 at the latest. And 443 total people are in quarantine.
Just one non-academic exposure location was reported in Friday's update: a Burger King in Roebuck, which is in Spartanburg County. The restaurant is located adjacent to Dorman High School. The high school was identified as an exposure location Jan. 27.
Residents who were at the fast-food restaurant Wednesday, Jan. 28 from 11:30 a.m. to 2:30 p.m. should monitor for symptoms through Feb. 18.
Symptoms typically begin to show about a week after exposure, but for some, the signs will not present until 21 days after exposure. Symptoms include a fever and a visible rash that almost always begins on the face.
DPH reported one new hospitalization for complications of the disease. Nineteen people have been hospitalized.
Of the 847 people infected since the outbreak began, 775 were confirmed to not have all recommended vaccine doses. The vaccination status of 52 people is unknown, and 20 cases have been in fully vaccinated people.
While not looming as large as South Carolina's measles presence, North Carolina began releasing twice-a-week updates to its case numbers mid-January. The state is up to 15 cases since December 2025.
