Abstract

SARS-CoV-2 (COVID-19) has undergone many changes and variants have been reported worldwide. Three variants that share the N501Y mutation were identified: one in the United Kingdom (UK) identified as B.1.1.7, one in Republic of South Africa identified as B.1.351, and one in Brazil identified as P.1. Although mutations are an expected part of the spread of any virus, continued monitoring, prevention and surveillance are essential. The aim of this report was to share the results of the medical triage response to the influx of COVID-19 variants at the Incheon Airport National Quarantine Station (IANQS). Findings indicated that the IANQS adapted the COVID-19 medical triage for variant countries through the adjustment of body temperature, epidemiological investigations of inbound arrivals, and COVID-19 polymerase chain reaction (PCR) testing of all inbound arrivals from variant countries. As a result of strengthened COVID-19 medical triage and reinforced quarantine for arrivals from variant countries, and by responding quickly to national policy according to the influx of variants, the first case from three variant countries was confirmed at the IANQS in December 2020(B.1.1.7), and two other variants were confirmed at the IANQS in January 2021(B.1.351, P.1). Although variant cases are expected to continue, community transmission was blocked in advance due to the medical triage response at the IANQS. This report recommended that the IANQS continue to block the spread of identified variants and be prepared to respond to emerging variants.
