초록

목적: 우리나라 강원도 내 어린이집, 유치원, 초중고(공교육) 교육시설과 사교육시설을 포함한 교육시설 관련 COVID-19 감염병 집단사례의 역학적 특성과 위험요인을 파악하고자 한다. 방법: 연구기간은 2020년 12월 10일부터 2021년 9월 23일까지 질병관리청 질병보건통합관리시스템에 신고된 강원도 내 코로나19 확진자 5,318명 중 교육시설 관련 집단감염으로 분류된 19개의 교육시설 관련 확진자 407명을 대상으로 조사하였다. 결과: 교육시설 관련 확진자는 19개의 교육시설 총 407명으로 19세 이하는 204명(50.1%) 이었다. 선행 전파자는 가족이 155명(38.1%), 교사125명(30.7%)이었다. 이차감염자가 확진자로부터 노출된 장소는 집이 139명(34.2%)으로 가장 높았다. 총 19개 집단에서 9개 집단의 근원 환자(추정)는 교사로 확인되었다. 교사가 선행 감염원인 경우의 평균 발병률(2.4%)이 학생이 근원 환자(추정)인 집단의 평균 발병률(1.5%)보다 높았다. 또한 교육시설 내 위험도 종합평가 점수가 높은 사교육시설에서 발병률과 2차 발병률이 높았다. 결론: 본 연구에서 교육시설보다는 가정에서의 전파가 더 큰 것이 확인되었고, 교육시설 내 위험도 종합평가점수가 높은 교육시설에서는 교내 발병률이 가정내 발병률보다 높았고, 공교육 시설보다 사교육시설의 위험도 점수가 높은 곳이 많았으며, 교사들이 근원 환자(추정)인 사례가 많았다. 이러한 결과를 근거로 학생들과 더불어 교사들의 방역 수칙 이행에 대한 감시의 강화가 필요하겠다. 또한 지속적인 교육 당국의 모니터링을 통해 감염병 범유행 상황에서 감염으로부터 안전한 환경에서 교육이 이행될 수 있도록 지속적으로 노력해야 할 필요가 있다.

Purpose: To identify the epidemiological characteristics and risk factors of coronavirus disease 19 (COVID-19) outbreaks depending on the type of educational facility by analyzing the COVID-19 cluster associated with educational facilities. Methods: This study is based on epidemiological investigation of COVID-19 cluster in Gangwon-do, Korea from December 10, 2020 to September 23, 2021 reported to the Korea Disease Control and Prevention Agency's Integrated Disease and Health Management System. Four hundred seven patients in 19 facilities, classified as cluster related to educational facilities, were the study population. The result of preliminary epidemiology survey report, in-depth epidemiological survey by phone and the result of risk assessment derived from the field epidemiology investigation were retrospectively analyzed to evaluate infectivity and the characteristics of the risk factors. Results: There were total of 407 confirmed patients related to 19 educational facilities, with 204 students under the age of 19 (50.1%). One hundred fifty-five preceding spreaders were from families (38.1%) and 125 were the teachers (30.7%). The place exposed to confirmed patients was the highest with 139 people (34.2%) at home. Conclusions: It was confirmed that the cause of the occurrence of clusters related to educational facilities was higher due to family transmission than the risk of facilities in schools. Nevertheless, continuous efforts should be made to control infection in educational facilities, and that teachers' implementation of principles for prevention of COVID-19 personal hygiene in their daily lives should be strengthened.
