中文摘要 | 2020年2月27日晚間A醫院1名住院病患確診新型冠狀病毒(SARS-CoV-2),疾病管制署、衛生局及醫院三方立即進行流行病學調查及接觸者採檢,於2月28日確診4名醫院工作者。由於3名為同一病房護理師,緊急運用「醫院因應院內發生COVID-19(武漢肺炎)確定病例之應變處置建議」進行擴大匡列接觸者及健康監視。監測至3月27日止,累計匡列456名接觸者,採檢409名,確診8例,未有院內其他單位或社區病例出現,成功防堵疫情擴展到社區。 指標個案無溯及已知的確定病例,研判感染源不明。指標病房內流行病學相關調查結果,推測傳播模式為人傳人及接觸污染環境而感染。 現階段全球COVID-19疫情仍持續發展,期透過整理及紀錄本事件的應變處置經驗做為未來醫院及衛生單位快速應變參考。 |
英文摘要 | Nosocomial transmission has been recognized as an important amplifier in epidemic of coronavirus disease-2019 (COVID-19). Infection of healthcare workers (HCWs) and patients will further overwhelm the healthcare system. On February 27, 2020, a patient at a tertiary hospital without foreign travel history was diagnosed as COVID-19 infection 12 days after admission. The Taiwan Centers for Disease Control, local health bureau and the hospital immediately conducted epidemiological investigation, contact tracing, and control measures in collaboration. From the close contacts of the index case, four COVID-19 cases were identified on February 28, of whom three were nurses working in the same ward as the index case (the index ward). Since more than one COVID-19 confirmed case was detected in the same unit, multiple transmission modes and infection chains were possible. Following the guidance of "Recommendations on contingency operations for hospitals in response to COVID-19 cases identified in inpatients”, we stepwise expanded the management and COVID-19 screening of person at-risk, closure of ward, environmental cleaning and disinfection, and enhanced symptoms surveillance of the hospital. By the end of monitoring period on March 27, we identified 153 HCWs and 303 non-HCWs as contacts. Among the 456 contacts, 409 were tested for COVID-19 and 8 were positive. The infection source of index case was unknown, and the epidemiological and environmental investigations indicated that both droplet and fomite transmissions were involved in the nosocomial infection. Through prompt investigation and stepwise intervention, including strict infection control, thorough contact tracing and symptoms monitoring during mandatory 14-day quarantine for the contacts, as well as rapid COVID-19 testing for person at-risk and symptomatic contacts, we successfully blocked the infection chain and preventing from further spread in the hospital or to the community. Now the global COVID-19 epidemic is still developing, this document provides our implemented experience as a reference for hospitals and health authorities encounter the similar outbreak in the future. |
