Abstract

Abstract: The Sunshine Coast Public Health Unit (SCPHU) identified a measles case in a childcare educator (CE) with secondary vaccine failure (SVF). The CE had been exposed to a confirmed measles case in a hospital emergency department and later developed symptoms including fever, cough, malaise, and a rash. Diagnostic tests confirmed measles virus infection. Sunshine Coast Public Health Unit (SCPHU) implemented control measures including contact tracing, vaccination, post-exposure prophylaxis, and quarantine for susceptible contacts. Out of 372 identified contacts, 72 were identified as susceptible, all of whom were infants and children. Despite the CE having close contact to all susceptible infants and children, no onward transmission occurred. This suggests that SVF cases pose a lower risk of spreading measles compared to immunologically naïve individuals. This report highlights the importance of prioritising immunologically naïve cases in outbreak responses.

儿童保育机构麻疹二次疫苗接种失败：疫情报告。

摘要：阳光海岸公共卫生股（SCPHU）发现一名儿童保育员（CE）感染了麻疹病例，并伴有继发性疫苗接种失败（SVF）。该儿童保育员曾在医院急诊科接触过一例麻疹确诊病例，随后出现发烧、咳嗽、不适和皮疹等症状。诊断检测证实他感染了麻疹病毒。阳光海岸公共卫生股（SCPHU）采取了控制措施，包括追踪接触者、接种疫苗、接触后预防以及对易感接触者进行隔离。在已确认的 372 名接触者中，有 72 人被确认为易感人群，他们都是婴幼儿。尽管行政长官与所有易感婴幼儿都有密切接触，但并未发生继续传播。这表明，与免疫力低下的人相比，SVF 病例传播麻疹的风险较低。这份报告强调了在应对疫情时优先考虑免疫力低下病例的重要性。
