AbstractAbstract AbstractSummary PDF
This study presents the response of a military unit to an outbreak of coronavirus disease 2019 (COVID-19) in Gyeonggi Province. As soon as 2 soldiers were identified as index cases, the infectious disease investigators of the Gyeonggi Provincial Government, Korea Disease Control and Prevention Agency, and the Armed Forces Epidemiologic Investigation Center discussed the investigation and response plan for an imminent massive outbreak.
The joint immediate response team (IRT) conducted interviews with confirmed COVID-19 patients, reviewed their medical records, performed contact tracing using global positioning system data, and undertook a field investigation. For risk assessment, the joint IRT visited all 8 sites of the military units and the army chaplain’s church to evaluate the transmission risk at each site. The evaluation items included the size of the site, the use of air conditioning, whether windows were opened, and whether masks were worn. Pooled testing was used for the low-risk population to quickly detect the spread of COVID-19 in the military base.
One day before the symptom onset of the index case, the lecturer and >50% of the attendees were infected with COVID-19 while attending a lecture that lasted 2 hours and 30 minutes. Attendees were not wearing masks and were in a poorly ventilated room.
Since COVID-19 can be spread before symptom onset, contact tracing must be performed to investigate potential exposures prior to symptom onset and to manage any exposed persons.
Korean summary
본 연구는 경기도 군부대에서 발생한 코로나19 대응 경험을 공유하는 국내 최초의 연구 결과이다. 본 연구를 통해 정리된 역학조사 과정은 군부대, 기숙사, 교정시설 등 집단 시설의 방역 대책 수립에 도움이 될 것으로 기대한다. 또한, 이번 사례는 집단 감염 발생 시 여러 유관 기관의 협조 체계가 신속한 대응과 추가 전파 예방에 중요하다는 점을 시사한다.
Key Message
This study is the first research in South Korea to share the experience of responding to COVID-19 at the military unit in Gyeonggi-do. The epidemiological investigation process organized through this study is expected to help establish response measures for group facilities such as military units, dormitories, and correctional facilities. In addition, this case suggests that the cooperative system of various related organizations in the event of a mass infection is important for rapid response and prevention of further transmission.
