Background: There are regional variations in the incidence of coronavirus disease 2019 (COVID-19), which means that some regionsare more exposed to the risk of COVID-19 than others. Therefore, this study aims to investigate regional variations in the incidenceof COVID-19 in Korea and identify risk factors associated with the incidence of COVID-19 using community-level data.
Methods: This study was conducted at the districts (si·gun ·gu) level in Korea. Data of COVID-19 incidence by districts were collectedfrom the official website of each province. Data was also obtained from the Korean Statistical Information Service and the CommunityHealth Survey; socio-demographic factor, transmission pathway, healthcare resource, and factor in response to COVID-19.
Community risk factors that drive the incidence of COVID-19 were selected using a least absolute shrinkage and selection operatorregression.
Results: As of June 2021, the incidence of COVID-19 differed by more than 80 times between districts. Among the candidate factors,sex ratio, population aged 20?29, local financial independence, population density, diabetes prevalence, and failure to comply withthe quarantine rules were significantly associated with COVID-19 incidence.
Conclusion: This study suggests setting COVID-19 quarantine policy and allocating resources, considering the community riskfactors. Protecting vulnerable groups should be a high priority for these policies.
