The [measles outbreak centered in Upstate South Carolina](https://www.wccbcharlotte.com/2026/04/21/upstate-sc-measles-outbreak-could-be-over-next-monday/) may be approaching its official end. Health officials say next Monday would mark 42 days since the last outbreak-related new case — the threshold required under public health protocol to formally declare an outbreak over. If no new cases emerge in the coming days, Spartanburg County could close a chapter on one of the largest measles outbreaks in South Carolina history.

The outbreak, which began last fall and accelerated through early 2026, reached nearly 1,000 confirmed cases statewide. According to data from the [Center for Infectious Disease Research and Policy](https://www.cidrap.umn.edu/measles/south-carolina-no-new-measles-cases-upstate-outbreak), approximately 940 of those cases were recorded in Spartanburg County, making it the epicenter of the outbreak. Greenville County accounted for most of the remaining cases. School-age children between 5 and 17 represented the largest age group affected, with 456 cases in that demographic.

The South Carolina Department of Public Health activated mobile vaccination units throughout the outbreak, offering free MMR (measles-mumps-rubella) shots at community sites including churches and community colleges in Spartanburg. The outbreak exposed gaps in vaccination coverage, particularly among school-age children whose families had filed religious or medical exemption forms with their districts. Exposure sites during the outbreak’s peak included two churches, a Costco, and a community college in Spartanburg County.

Public health officials and epidemiologists have emphasized that the outbreak’s scale — nearly 1,000 cases in a single county — reflects the consequences of declining MMR vaccination rates over the past decade. South Carolina’s immunization rates have trailed Georgia and North Carolina in recent years, raising concerns about herd immunity in certain communities. State lawmakers have been weighing legislation to tighten exemption standards, though no final action has been taken.

For Spartanburg County residents, the near-end of the outbreak is welcome news, but public health officials are urging families not to treat Monday as a reason to defer vaccinations. The SC Department of Public Health encourages all residents — especially parents of school-age children and those planning travel — to verify their MMR coverage with a healthcare provider. Reaching and maintaining community immunity levels is the only durable protection against a repeat of this year’s experience.
