Ninh Tran: 安大略省西南部地区正在经历严重的麻疹疫情,疫情主要发生在未接种疫苗或疫苗接种不全的人群中,尤其是在18岁以下的儿童中。疫情的严重程度是几十年来未见的。麻疹会引起并发症,虽然大多数病例可以在家康复,但一些病例需要就医并住院治疗。目前的病例数被低估了,因为并非所有感染者都会就医或接受检测。为了控制疫情,我们加大了病例和接触者管理的工作力度,增加了免疫接种能力,并为6到11个月大的婴儿提供额外剂量的疫苗。我们还鼓励更早接种第二剂疫苗,并进行健康宣传和沟通工作。但麻疹的传染性极强,接触者追踪工作非常具有挑战性。目前还难以判断疫情何时结束,需要持续监测。 Marissa Lattin: 我的七个月大的儿子患有囊性纤维化,在医院接受检查时接触到麻疹病例,这让他面临更大的风险。医院采取了隔离措施,并为他注射了免疫球蛋白,但这并不能完全保证他不会感染麻疹。这让我非常担忧,也突显了麻疹疫情对免疫功能低下人群的威胁。所有这些都是可以避免的,疫苗接种可以阻止这一切。 Lenora Saxinger: 加拿大正在经历麻疹疫情,疫情的传播速度取决于人口的免疫接种率。麻疹的潜伏期长,早期症状不典型,增加了疫情防控的难度。麻疹疫苗的错误信息长期存在,疫情期间有所加剧,导致疫苗接种率下降。一些社区的麻疹疫苗接种率很低,这使得这些社区更容易受到麻疹疫情的影响。为了获得足够的群体免疫力,需要95%的人口完成疫苗接种。麻疹可导致严重的并发症,包括肺炎、肝炎和脑炎等,这些并发症是可预防的。我认为加拿大政府在麻疹疫情的沟通方面做得不够充分。未来加拿大麻疹疫情可能继续出现散发病例,但不太可能恢复到持续传播的状态。 Brian Goldman: 麻疹是一种严重的疾病,应该接种疫苗以保护自己和他人。我小时候得过麻疹,也曾在医院见过麻疹病例,这是一种你不想得,也不想传播的疾病。

Shownotes Transcript

We're seeing the worst measles numbers in Canada in more than a decade. Dr. Ninh Tran, medical officer of health in the country's hardest hit region of southwestern Ontario, describes how they're fighting to control the spread. And University of Alberta infectious diseases specialist Dr. Lynora Saxinger reflects on the "undead zombie of disinformation" that's helped lead us here.
