Measles Cases Surge 1277% Since 1992 Amid Vaccine Hesitancy
-
最新报道：Measles cases in the U.S. have surged to 1,277 this year, the highest since 1992, as vaccine hesitancy grows among parents. Health officials warn the highly contagious disease is spreading rapidly in undervaccinated communities, with outbreaks reported in 31 states. The CDC attributes the rise to misinformation about vaccine safety and declining immunization rates. Measles was declared eliminated in the U.S. in 2000, but recent imported cases have exposed protection gaps. Authorities urge parents to vaccinate children, emphasizing the MMR vaccine's 97% effectiveness rate after two doses. Schools in affected areas are implementing exclusion policies for unvaccinated students during outbreaks.
