We analyzed the COVID-19 test results of overseas entrants through Incheon International Airport in 2022. The total number of tests was 21,234, of which 6,149 were confirmed positive, and the positive rate was 29.0%, a significant increase from 5.3% in 2021. The increased test number, due to the prevalence of Omicron, was lasted until March 2022 and gradually decreased until June. The positive rate was also decreased to 5.6% in June. After that, the test number and positive rate began to increase again, and the positive rate was maintained from 34.9% to 59.3% until December. The COVID-19 tests were conducted on overseas entrants from 128 countries. The order of the top 15 countries was Unites States, Vietnam, Japan, etc. The number of tests in the top 15 countries was 16,498, which was 77.7% of the total number of tests. In the first half of the year, there were many tests conducted in the United States, Japan, Canada, etc., and in the second half, increased number of tests was confirmed in Philippines, Thailand, Vietnam, etc. The positive rates for each country showed a similar trend to the overall positive rate changes in most country including the 15 countries. This trend is presumed to be the result of mitigation of quarantine measures by stabilizing of the outbreak of COVID-19 due to Omicron and vaccination. As such, we will maintain a rapid and accurate laboratory inspection system to prevent and control infectious diseases derived from abroad such as COVID-19 at quarantine stage.
