Rachel Feltman: 我主要关注当前美国麻疹疫情的严重性以及对已获得的麻疹消除状态的潜在威胁。我强调了自1月底以来美国确诊的超过1000例病例,特别是在西德克萨斯州发生的聚集性疫情,这是近年来最严重的疫情之一。尽管美国在2000年已宣布消除了麻疹,但这些疫情的出现令人担忧。我希望通过与Lauren Young的对话,能够帮助听众了解麻疹消除状态的含义,以及我们目前面临的风险。 Lauren Young: 我认为目前美国的麻疹疫情正在恶化,病例数持续上升,截至5月1日,CDC报告已确诊935例,且疫情已蔓延至29个州以及墨西哥和加拿大。更令人担忧的是,约70%的病例发生在19岁以下的年轻人中,且大部分病例发生在未接种疫苗的人群中。麻疹具有高度传染性,可能导致严重的并发症甚至死亡。此外,疫苗接种率的下降、反疫苗言论的增加以及公共卫生官员对疫苗的质疑都加剧了疫情的风险。我认为,除非我们采取积极措施提高疫苗接种率,否则美国可能会失去麻疹消除状态。

Measles was technically “eliminated” in the U.S. in 2000 thanks to high measles, mumps and rubella (MMR) vaccination rates. While prior outbreaks have made headlines, a slew of cases in West Texas is more than just newsworthy—it could cause the U.S. to lose elimination status. Associate health and medicine editor Lauren Young explains what elimination means, why measles cases are rising and how to prevent further transmission.
