Abstract
The Korea Disease Control and Prevention Agency conducts quarantine inspections of individuals entering the Republic of Korea (ROK) who have visited quarantine inspection areas or strict quarantine inspection areas—designated by quarantine law Article 12-2 duty to report and measures, etc. Inspections are viewed as necessary for addressing the risk of infectious diseases occurring overseas and preventing their domestic influx. Upon arrival, an individual is required to submit a health declaration form with their name, passport number, address in the ROK, contact information, and symptoms (if any) for the quarantine inspection. To prevent the spread of coronavirus disease 2019 (COVID-19) outbreaks, beginning July 1, 2020, the entire world was designated as a quarantine inspection areas As a result, all individuals entering the ROK are required to submit certain documents, such as a health declaration form, travel record declaration, certificate of immunization, COVID-19 medical certification, and quarantine exemption application, to quarantine officials. As the number of individuals subjected to quarantine has increased, the waiting time for a quarantine inspection upon entry has also increased. To efficiently address the confusion among incoming travelers due to the complex quarantine procedures, the pre-questionnaire systems for quarantine information (hereafter, Q-CODE) has been introduced.
