Abstract

Sections

The purpose of this report was to present the characteristics of the quarantine response to COVID-19 by analyzing indicators at the Incheon Airport National Quarantine Station (the IANQS). In 2020, quarantine in South Korea gradually strengthened following the global spread of COVID-19. As a result, the daily number of inbound travelers decreased, but the collection rate of health declaration forms(HDFs) reached 96.6 percent of those who entered South Korea.
The target period for analysis was from January 2nd to May 15th, 2020 and the main results are as follows.
First, the total number of quarantine targets was 5,690,933, and the collected number of HDFs was 892,918. A total of 405 patients including the first confirmed patient(#1) were confirmed by the IANQS among patients under investigation(PUIs) who were detected at the quarantine phase.
Second, cases with COVID-19 symptoms were affected by the outbreak trends of the departure country. From January to the end of February 2020, the majority of cases with symptoms departed from China, and after March, the number of cases with symptoms increased significantly due to the spread of COVID-19 in Europe and the Unitede States. Flight analyses showed the same results that the percentage of PUI passengers was high in flights from departure cities with high prevalence.
Third, 84% of 404 confirmed cases from March 14th to May 15th, 2020 had been in Europe and the United States.
