Importantly, individuals infected with measles are contagious for a period spanning four days *before* the rash appears and continuing for four days *after* its onset, facilitating rapid spread.
Current Outbreak in Northern South Carolina
A measles outbreak is currently concentrated in the northern region of South Carolina,particularly within Spartanburg and Greenville Counties. These counties are experiencing lower-than-recommended vaccination rates,contributing to the outbreak’s persistence.
Vaccination rates for the 2024-2025 school year reached 90% in Spartanburg County and 92.4% in Greenville County. Public health officials aim for a 95% vaccination rate to achieve herd immunity and prevent widespread community transmission.
Compounding the issue, both counties have elevated rates of religious exemptions to school vaccination requirements. Spartanburg County reports the highest rate in the state at 8.2%, while greenville County’s rate is 5.3%.
Case Data and Vaccination Status
As of the latest data, 111 cases have been identified in the outbreak. A significant majority – 105 cases – involved unvaccinated individuals. Three cases were partially vaccinated, two had an unknown vaccination status, and only one case occurred in a fully vaccinated person.
National Trends and Contributing Factors
Nationally, measles cases are on the rise, reaching a 33-year high with nearly 2,000 cases and 46 outbreaks reported this year. This increase is linked, in part, to the spread of misinformation regarding vaccines, including claims made by figures like Health Secretary Robert F. Kennedy Jr. You can find the latest national measles data from the Centers for Disease Control and Prevention (CDC).
