美国麻疹病例突破1281例,创2000年宣布消灭后新高。疫苗接种率下降,专家预测美国可能失去消灭状态,呼吁维持95%以上的接种率以阻止传播。

Over the weekend, the tally of measles cases reached 1,281, setting a new case record since the highly contagious viral disease was declared eliminated from the country in 2000. The previous record was set in 2019, when there were 1,274 cases and officials warned that the US had narrowly avoided losing the elimination status.

Overall, the current case tally is a 33-year high for the preventable infection, and the outlook for the country is bleak. Vaccination rates have only fallen since the pandemic, and the top health official in the country—Robert F. Kennedy Jr.—is an unswerving anti-vaccine activist who has spent his short time in the position so far spreading dangerous misinformation about the measles vaccine—as well as peddling unproven treatments and downplaying the infection.

Experts expect that the US will lose its elimination status, which will occur if the virus spreads uninterrupted for 12 months. To block transmission, experts say populations must maintain vaccination rates of 95 percent or higher. But, nationally, the vaccination rate among kindergartners has fallen to 92.7 percent in the latest data, with some communities having vaccination rates far lower, leaving them vulnerable to widespread outbreaks.
