Brian Goldman: 本期节目讨论了加拿大和美国正在蔓延的麻疹疫情,这是一种曾接近被根除的疾病,现在却在多个省份卷土重来。由于疫苗接种率的下降以及新冠疫情期间疫苗接种中断等因素,麻疹疫情的规模有所扩大。 Suman Chakrabarti医生:我最近也遇到过麻疹病例,虽然不多,但数量正在增加。麻疹的传播方式主要通过呼吸道飞沫,具有极高的传染性,感染者即使离开房间后,病毒仍可在空气中存留数小时。麻疹的症状通常包括发烧、咳嗽、流鼻涕、眼睛发红,然后出现皮疹,皮疹从脸上开始,逐渐蔓延到全身。 麻疹可能导致严重的并发症,包括肺炎、心肌炎、脑膜炎、脑炎,甚至死亡。有些并发症可能需要数年才能显现。 麻疹疫苗非常有效,两剂疫苗的保护率超过95%,并且不会导致自闭症。对于前往麻疹高发地区旅行的人群,特别是12个月以下的婴儿和免疫功能低下的人群,需要特别注意接种疫苗。 Suman Chakrabarti: 麻疹是通过呼吸道飞沫传播的,具有高度传染性,感染者即使离开房间后,病毒仍可在空气中存留长达两小时,这使得麻疹成为一种“超级传播者”病毒。 麻疹的症状通常包括发烧、咳嗽、流鼻涕、眼睛发红,然后出现皮疹,皮疹从脸上开始,逐渐蔓延到全身。 麻疹可能导致严重的并发症,包括肺炎、心肌炎、脑膜炎、脑炎,甚至死亡,有些并发症可能会持续数年,例如亚急性硬化性全脑炎 (SSPE)。 麻疹疫苗非常有效,两剂疫苗的保护率超过95%,并且不会导致自闭症。对于前往麻疹高发地区旅行的人群,特别是12个月以下的婴儿和免疫功能低下的人群,需要特别注意接种疫苗。 过去,麻疹主要在疫苗接种率低的特定人群中传播,但现在由于多种因素,例如政治动荡、人口迁移以及新冠疫情期间疫苗接种中断,导致未接种疫苗的人数增加,从而增加了疫情暴发的风险。
