Abstract
|
|
|
|
The Korea Disease Control and Prevention Agency has been conducting a complete investigation of coronavirus disease 2019 (COVID-19) confirmed patients and their contacts. In January 2022, the number of confirmed cases increased rapidly due to the development of dominant Omicron variants, which demanded a new quarantine response strategy. On February 7, 2022, a self-report COVID-19 case reporting form was introduced, allowing confirmed patients to enter their basic epidemiological information in the questionnaire. In the fourth quarter of 2022, the registration status of the COVID-19 case reporting form was 98.9%. The registration rate using the self-report COVID-19 case reporting form continued to rise monthly. In the status of each major item, no differences were found in terms of presence of symptoms, underlying diseases, time taken for the diagnosis of confirmed diseases, and the ratio of members of facilities vulnerable to infection. With respect to the status of cohabitants, no significant change in the number of cohabitants per index patient was observed; however, the secondary incidence rate tended to decrease by a small degree every month. There may be limitations in generalizing the monitoring results because input values are not verified for COVID-19 case reporting form data. Therefore, it is necessary to verify the accuracy of the data registered in COVID-19 case reporting form by comparing each item with other objectified data sources. It will be used as evidence for policy preparation through additional analysis of each item of the COVID-19 case reporting form.
