South Carolina Measles Outbreak: Delays and Challenges in Containment

South Carolina is experiencing one of the largest measles outbreaks in the United States in decades. As of February 10, 2026, there are 933 confirmed cases, a significant increase from the initial five cases reported in October 2025. The outbreak has been complicated by delays in contact tracing and quarantine efforts, particularly during the recent holiday season, raising concerns about the effectiveness of containment strategies.

The Impact of School Closures and Holiday Staffing Shortages

A key challenge in controlling the outbreak stemmed from difficulties in obtaining timely contact information from schools during the winter break. Schools were closed from December 22, 2025, to January 5, 2026, hindering public health officials’ ability to quickly warn potentially exposed individuals. According to Dr. Linda Bell, South Carolina’s state epidemiologist, “DPH made many efforts to reach impacted schools over the holidays with limited success as the schools were closed.”

The South Carolina Department of Public Health (DPH) also faced internal staffing challenges during December, with a reduction in staff assigned to combat the outbreak. Internal reports highlighted concerns about holiday staffing, workloads, burnout and limited support due to workforce reductions implemented in April 2025. Staffing levels began to increase significantly after New Year’s Eve.

Exposure Locations and Expanding Reach

The outbreak’s impact extends beyond schools, with reported exposures in healthcare facilities, including a hospital labor and delivery unit, and workplaces such as manufacturing plants for BMW and Michelin. Records obtained by Healthbeat reveal that infectious individuals from South Carolina have also spread the virus to other states, including incidents at a youth conference in Kentucky, a hospital in Florida, and travel convenience stores in Georgia and Texas.

Delays in Contact Tracing and Quarantine

Internal DPH reports indicate delays in notifying and quarantining individuals exposed at five schools in Spartanburg County during the winter break: Global Academy of South Carolina (a public charter school), and elementary schools in Districts 2 and 6. At Global Academy, where only 21% of students are up-to-date on required vaccinations, it took until January 9, 2026, to receive a complete list of exposed students and staff. The department even prepared a public health order to compel compliance from Westgate Christian School when contact information was not promptly provided.

Dr. Bell acknowledged that the delays hampered the department’s ability to rapidly identify and quarantine exposed individuals, stating, “Our inability to get contact information for potentially exposed students and families resulted in some people being out and about in the community without knowing that they were infectious.”

Challenges with School Communication and Nurse Availability

School officials from Spartanburg County’s Districts 2 and 6 have declined to comment on the outbreak’s impact and the circumstances surrounding the investigation delays. A significant challenge lies in the availability of school nurses and staff during breaks, as they are often not paid to work during these periods. Pat Endsley, president-elect of the National Association of School Nurses, noted the lack of a national best practice for addressing school contact tracing during extended breaks.

Successful Communication Models in Other States

In contrast to South Carolina, the Southwest Utah Public Health Department reported no difficulties reaching impacted schools over the winter break, attributing their success to frequent communication with established points of contact within the largest school district. The Mohave County Department of Public Health in Arizona emphasized the importance of established communication protocols and coordination between public health and education partners.

Looking Ahead

The South Carolina measles outbreak is ongoing, with 950 confirmed cases as of last week. Scott Thorpe, executive director of the Southern Alliance for Public Health Leadership, emphasized that the situation in South Carolina is not unique, as pockets of low vaccination rates are common in other communities. Strengthening communication between public health departments and schools is crucial to effectively respond to future outbreaks, particularly as measles cases continue to rise across the United States, with at least 24 states reporting cases to the Centers for Disease Control and Prevention so far this year.
