South Carolina's measles outbreak has taken a devastating turn, claiming the top spot as the largest in U.S. history since its eradication in 2000. According to recent data from the state health department, a staggering 789 cases of measles have been reported, surpassing all previous outbreaks.
The majority of these cases – over 600 in 2023 alone – have emerged in children under the age of 11, with infants and toddlers also significantly affected. An alarming 692 of those infected are unvaccinated, highlighting the urgent need for parents to ensure their children receive the necessary vaccinations.
Spartanburg County, with its large population of over 350,000, is particularly hard hit, accounting for nearly all reported cases – an astonishing 756 out of 789. The county's health officials have expressed concerns that the situation may worsen in the coming weeks.
As the measles outbreak continues to spread rapidly across the state, public health experts are sounding the alarm about the dangers of vaccination decline. Dr. Johnathon Elke of Prisma Health warned earlier this year that "we feel like we're really kind of staring over the edge, knowing that this is about to get a lot worse."
With nearly 88% of reported cases among unvaccinated individuals, it's clear that measles is no longer just a distant threat, but an immediate and tangible reality. As vaccination rates continue to dip, especially among school-age children, the risk of further outbreaks grows.
The data from this outbreak highlights a worrying trend: in 2019, childhood vaccinations against measles reached 95%, but by 2023, that number had fallen to just 92%. This decline is happening at an alarming rate, with the current outbreak spreading faster than the 2025 nationwide outbreak, which saw 2,255 confirmed cases.
