The coronavirus disease 2019 (COVID-19) pandemic has continued since its first detection in the Republic of Korea on January 20, 2020. This study describes the early countermeasures used to minimize the risk of COVID-19 outbreaks during cohort quarantine and compares the epidemiological characteristics of 2 outbreaks in long-term care facilities (LTCFs) in Gwangju Metropolitan City in summer 2020.
An epidemiological investigation was conducted via direct visits. We investigated epidemiological characteristics, including incidence, morbidity, and mortality rates, for all residents and staff members. Demographic characteristics were analyzed using a statistical program. Additionally, the method of managing infection in LTCFs is described.
Residents and caregivers had high incidence rates in LTCF-A and LTCF-B, respectively. LTCF-B had a longer quarantine period than LTCF-A. The attack rate was 20.02% in LTCF-A and 27.9% in LTCF-B. The mortality rate was 2.3% (1/43) in LTCF-B, the only facility in which a COVID-19 death occurred.
Extensive management requires contact minimization, which involves testing all contacts to mitigate further transmission in the early stages of LTCF outbreaks. The findings of this study can help inform and prepare public health authorities for COVID-19 outbreaks, particularly for early control in vulnerable facilities.
自2020年1月20日在韩国首次发现新型冠状病毒肺炎（COVID-19）疫情以来，疫情仍在持续。本研究描述了在队列隔离期间为尽量降低COVID-19暴发风险而采取的早期应对措施，并比较了2020年夏季光州市长期护理机构（LTCFs）中2起疫情的流行病学特征。
通过直接走访进行流行病学调查。我们调查了所有居民和工作人员的流行病学特征，包括发病率、患病率和死亡率。使用统计程序分析人口统计学特征。此外，还描述了长期护理机构的感染管理方法。
在LTCF-A中居民发病率高，在LTCF-B中护理人员发病率高。LTCF-B的隔离期比LTCF-A长。LTCF-A的感染率为20.02%，LTCF-B的感染率为27.9%。LTCF-B的死亡率为2.3%（1/43），是唯一出现COVID-19死亡病例的机构。
广泛的管理需要尽量减少接触，这包括对所有接触者进行检测，以减轻长期护理机构疫情早期阶段的进一步传播。本研究结果可为公共卫生当局应对COVID-19疫情提供参考并做好准备，特别是对脆弱机构的早期控制。
