South Carolina Measles Surge Triggers National Alarm Across the U.S.
South Carolina's Measles Surge Signals National Alarm
South Carolina's measles outbreak has exploded to 847 cases as of January 30, 2026, eclipsing Texas's 2025 total and becoming the largest in recent U.S. history.[1][2] Centered in Spartanburg County since October, the virus spreads through community sites, with 94% of national 588 cases this year unvaccinated or unknown status.[1][5] Public health officials warn of escalating risks as exposure grows beyond close contacts.[1]
Why Vaccination Gaps Fuel the Fire
Kindergarten vaccination rates dropped to 92% by 2023, down from 95% in 2019, eroding herd immunity.[4] In South Carolina, 88% of cases hit unvaccinated individuals, mostly under 19, with the virus lingering in air for two hours.[4][7] Nationally, 2025 saw 2,267 cases, the highest since 1991, projecting over 7,000 for 2026 if trends hold.[2] Experts like Dr. Johnathon Elke fear it's "about to get a lot worse."[4]
Implications for All Americans
This outbreak in one state ripples nationwide, with cases in 17 jurisdictions and 94% outbreak-linked.[5] Falling immunity threatens resurgence of this highly contagious disease, declared eliminated decades ago. Boosting MMR shots is crucial to safeguard communities everywhere and prevent broader crises.[2][6]
