中文摘要 | 2019年4月疾病管制署接獲1名香港境外移入麻疹病例通報確診,至5月期間北部地區共有17名麻疹確診個案,經比對暴露期活動史均與指標個案有直接或間接流行病學關聯。18名病例感染病毒型別均為B3型,研判為境外移入引發本土麻疹群聚事件,共引起3波疫情,發生場域為餐廳、醫院、職場及住宅。 病患年齡介於19至38歲,均為麻疹疫苗接種世代。臨床症狀包含發燒(83%)及紅疹(94%)。惟39%之病患無咳嗽(Cough)、流鼻水(coryza)或結膜炎(conjunctivitis)等典型麻疹症狀。65%於急性期採檢之血液抗體檢驗結果為IgM陰性及IgG陽性。 建議衛生單位增加民眾對麻疹傳播途徑與疾病特性認知,生病時避免出入公共場所;醫護人員可透過了解患者病程及接觸史,同時進行麻疹分子生物及抗體檢驗,以及早診斷避免疫情傳播。 |
英文摘要 | On April 3, 2019, a 29-year-old male was notified as a suspect case of measles (index case). Later he was confirmed as an imported measles case according to the laboratory results and travel history to Hong Kong. From April to May, additional 17 confirmed measles cases occurred in northern region of Taiwan, which all had direct or indirect epidemiological links to the index case, including common exposure in a restaurant (n=7), a hospital (n=4), a workplace (n=5), and in the household (n=1). Virus isolation from all 18 cases revealed identical genotype B3. All the cases were adult, with the mean age of 28 years (range: 19–38 years). Nine (50%) had received >1 dose of measles-mumps-rubella (MMR) vaccine. Fever (83.3%) and rash (94.4%) were the most common symptoms, and seven (39%) did not present cough, coryza, or conjunctivitis. This outbreak highlighted that young adults who were unvaccinated or with partial or waned immunity are susceptible to measles. Modified symptoms characterized with a milder rash or less intense symptoms may lead to challenges in early recognition. |
