Abstract
|
|
|
As the number of confirmed cases of coronavirus disease 2019 (COVID-19) around the world peaked in 2022 and has
continued to decline, several countries have eased prevention and control measures against COVID-19. In the Republic of
Korea, COVID-19 had been designated as class 1 infectious disease from January 20, 2020 to April 24, 2022. In consideration of high vaccination rate, introduction of therapeutic agents and the characteristics of variants, COVID-19 has been reclassified to class 2 infectious disease since April 25, 2022. Korea Disease Control and Prevention Agency (KDCA) analyzed the characteristics of COVID-19 outbreaks during designation of class 1 infectious disease in the Republic of Korea. In total, there were 16,929,564 COVID-19 confirmed cases, including 31,828 imported cases during this period. The
incidence rate was 32,785 per 100,000 population and the maximum number of confirmed cases per day was 621,177.
Severe and critical cases were 22,137 and the case fatality rate was 0.14% with 23,045 death cases. Among all the cases,
9,084,961 (53.8%) occurred in the Seoul metropolitan area (Seoul, Incheon and Gyeonggi Province) and 7,812,775 (46.2%)
occured in areas outside the Seoul metropolitan area. Among the confirmed cases, 4,117,327 (24.3%) were 18 or under 18
years old, 9,812,940 (58.0%) were between 19-59 years old and 2,999,299 (17.7%) were 60 or over 60 years old.
Through the lessons learned from pharmacological and non-pharmacological interventions and public health measures for the COVID-19 pandemic, Korean government should prepare for the next COVID-19 resurgence will be caused by new
variants or waning of acquired immunity as time passed.
