In the epidemiological investigation of an infectious disease, investigating, classifying, tracking, and managing contacts by identifying the patient's route are important for preventing further transmission of the disease. However, omissions and errors in previous activities can occur when the investigation is performed through only a proxy interview with the patient. To overcome these limitations, methods that can objectively verify the patient's claims (medical facility records, Global Positioning System, card transactions, and closed-circuit television) were used for the recent ongoing coronavirus disease 2019 contact investigations in South Korea.
在传染病的流行病学调查中，通过确定患者的行动轨迹来调查、分类、追踪和管理接触者对于预防疾病的进一步传播至关重要。然而，仅通过与患者进行代理访谈来开展调查时，之前的活动可能会出现遗漏和错误。为克服这些局限性，韩国在近期正在进行的2019冠状病毒病接触者调查中使用了能够客观核实患者说法的方法（医疗机构记录、全球定位系统、银行卡交易和闭路电视）。
