Public Health Weekly Report 2022; 15(27): 1908-1922This report aimed to analyze confirmed cases of coronavirus disease 2019 (COVID-19) among imported cases at the Incheon Airport National Quarantine Station (IANQS) and to report on their epidemiological characteristics and trends while under quarantine.
In 2021, among the 11,961 imported COVID-19 cases, 1,287 (10.8%), excluding those confirmed via air ambulance, were confirmed through quarantine at the IANQS. Of these, 849 (66.0%) were male and 616 (47.9%) were in their 20s and 30s. Approximately 76.2% of the cases were Korean nationals.
According to the findings, approximately 19.3% of the cases were observed in June due to an increase in imported cases from Indonesia while, the number of imported cases gradually decreased to 2.8% in November. An analysis of the quarterly distribution of confirmed cases showed the highest number (n=420) in the third quarter and a rapid decrease in the fourth quarter (n=124). The decrease in confirmed cases was attributed to the reduced number of patients with symptoms and quarantine targets who were subjected to testing, from 2,941 in January to 1,000 in March and less than 1,000 after August. Among the 14,977 symptomatic cases and quarantine targets, 1,263 were confirmed (8.4%). Only 860 (66.8%) of 1,287 total confirmed cases were symptomatic. An additional 261 (20.3%) showed unrecognized fever during quarantine without reporting symptoms and 166 (12.9%) were asymptomatic. Among foreign nationals, 169 cases of unrecognized fever were reported, more than twice the 78 confirmed symptomatic cases.
In summation, the new COVID-19 variants and increased vaccination rates led to changes in the overall quarantine situation and the number of COVID-19 cases confirmed during quarantine in 2021. Analysis of these epidemiological characteristics is expected to povide reference data for future quarantine responses.

Public Health Weekly Report 2022; 15(27): 1923-1934The number of reported cases of infectious diseases in 2021 increased by 669,477 cases (301.6%) compared to 166,716 cases in 2020 due to the rapid increase in emerging infectious disease syndrome (Coronavirus disease 2019). The number of reported cases decreased by 6.2% year-on-year to 99,405 cases excluding emerging infectious disease syndrome (COVID-19). Also, the number of major respiratory infectious diseases decreased 23.1% year-on-year and the number of cases of foreign inflow infectious diseases (excluding COVID-19) decreased by 73.3% year-on-year. The deaths of infectious diseases also showed a decreasing trend. However, despite these trends of decreasing infectious diseases excluding COVID-19, it is necessary to prevent the increase of other infectious diseases after declining of COVID-19 by strengthening monitoring and preparedness for other infectious diseases.

Public Health Weekly Report 2022; 15(27): 1935-1943The purpose of this study was to determine the consumption of vitamins D and E in the Republic of Korea. Food composition database for vitamins D and E was developed based on the 2016-2020 Korea National Health and Nutrition Examination Survey (KNHANES). The 2020 KNHANES (Ⅷ-2) was used to estimate the intake of vitamins D and E among Koreans.
The mean vitamin D intake was 3.1 ㎍, which was 31% of their adequate intake. The mean vitamin E intake was 6.5 mg α-TE, which was 57% of their adequate intake. As both vitamin D and E intake among Koreans was insufficient compared to adequate intake, continuous monitoring and interest for vitamin D and E are deemed to be necessary.
