South Carolina

• 南卡罗来纳州卫生官员在历时六个月后，宣布结束了全美规模最大的麻疹疫情。此次疫情共造成 997 人感染，21 人住院治疗，无死亡病例。 • 在超过一个月没有出现新增病例后，此次疫情于周日正式宣告结束。 • 在全国范围内对疫苗接种的担忧日益加剧之际，这标志着一个重大的公共卫生里程碑。

• In late March 2026, the South Carolina Senate passed heavily amended H. 3924, regulating rather than banning hemp-derived THC products like drinks and gummies. • The bill restricts sales to those 21 and older, tightening safety standards to close 2018 Farm Bill loopholes on high-potency THC. • Legislation now returns to the House for concurrence before the May 7, 2026, deadline.

The Centers for Disease Control and Prevention reported 1,362 confirmed measles cases nationwide in 2026, with 94% linked to ongoing outbreaks. South Carolina's outbreak, which began in October 2025, has decelerated to approximately 10 cases per week after peaking at 200 weekly cases in mid-January, bringing the state total to 996 cases as of March 13. Utah's outbreak, originating in June 2025, has accelerated to 405 cases as of March 10, representing a 47-case increase in one week. Both states currently host the largest active measles outbreaks in the United States.

A major measles outbreak in South Carolina is showing signs of slowing, with cases nearing 1,000 total and new infections dropping to about 10 per week from a peak of 200 weekly in mid-January. State health officials report a consistent downward trend over several weeks amid vaccination efforts. The decline matters as it reduces strain on public health resources in a state hit hardest by the outbreak. Monitoring continues to prevent resurgence through summer.
