Lassa fever is an acute viral hemorrhagic disease prevalent in West Africa. West China Hospital of Sichuan University (WCHSCU) received China's first imported case of Lassa fever from overseas. We described the epidemiological investigation and infection prevention and control measures of this case following the confirmed diagnosis.
An emergency epidemiological team defined close contacts and implemented infection prevention and control (IPC) measures: (1) isolation in a designated isolation room, (2) environmental disinfection for high-, medium-, and low-risk areas, (3) 21-day quarantine for contacts. Data were collected via field observations and medical records.
We identified 6 close contacts and 74 general contacts, who were subsequently quarantined for 21 days. The hospital environment was classified into high, medium, and low-risk areas, and corresponding cleaning and disinfection measures were implemented. Ultimately, no new infection cases emerged.
Rapid risk stratification, strict isolation protocols, and multidisciplinary coordination effectively prevented transmission, underscoring the importance of preparedness in non-endemic regions.
拉沙热是一种在西非流行的急性病毒性出血热疾病。四川大学华西医院接收了中国首例境外输入性拉沙热病例。确诊后，我们描述了该病例的流行病学调查及感染预防与控制措施。
一支应急流行病学团队确定了密切接触者并实施感染预防与控制（IPC）措施：（1）在指定隔离病房隔离，（2）对高、中、低风险区域进行环境消毒，（3）对接触者进行21天隔离观察。通过现场观察和病历收集数据。
我们确定了6名密切接触者和74名一般接触者，随后对他们进行了21天隔离观察。医院环境被划分为高、中、低风险区域，并实施了相应的清洁和消毒措施。最终，未出现新的感染病例。
快速的风险分层、严格的隔离方案以及多学科协作有效地预防了传播，凸显了非流行地区做好准备工作的重要性。
