Abstract
|
|
|
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.
