Ewha Womans University launched an on-campus Coronavirus disease-19 (COVID-19) response system called Ewha Safety Campus (ESC) Project in collaboration with the Seegene Inc. RT-PCR diagnostic tests for COVID-19 were proactively provided to the participants. This study examines the effectiveness of the on-campus testing strategy in controlling the reproduction number ( ) and identifying student groups vulnerable to infection.
The ESC project was launched on March 2, 2022, with a pilot period from Feb 22 to March 1, 2022-the peak of the Omicron variant wave. We collected daily data on the RT-PCR test results of the students of Ewha Womans University from Mar 2 to Apr 30, 2022. We daily calculated and compared it with that of the general population of Korea (women, people aged 20-29 years, and Seoul residents). We also examined the students vulnerable to the infection based on the group-specific and positivity rate.
A lower was observed about 2 weeks after the implementation of the ESC Project than that of the general population. The lower persisted during the entire study period. Dormitory residents had a higher . The positivity rate was higher in students who did not comply with quarantine guidelines and did not receive the second dose of the vaccine.
The study provides scientific evidence for the effectiveness of the on-campus testing strategy and different infection vulnerabilities of students, depending on dormitory residence, compliance with the quarantine guidelines, and vaccination.
梨花女子大学与Seegene公司合作推出了一个名为“梨花安全校园（ESC）项目”的校内新型冠状病毒肺炎（COVID-19）应对系统。该项目为参与者主动提供了COVID-19的逆转录聚合酶链反应（RT-PCR）诊断检测。本研究旨在探讨校内检测策略在控制传播数（ ）以及识别易感染学生群体方面的有效性。
ESC项目于2022年3月2日启动，2022年2月22日至3月1日为试点期，此期间正值奥密克戎变异株流行高峰。我们收集了梨花女子大学学生在2022年3月2日至4月30日期间RT-PCR检测结果的每日数据。我们每日计算 ，并将其与韩国普通人群（女性、20 - 29岁人群以及首尔居民）的传播数进行比较。我们还根据特定群体的 和阳性率来检查易感染学生群体。
ESC项目实施约2周后观察到传播数低于普通人群。在整个研究期间，较低的传播数一直持续。宿舍居住者的传播数较高。未遵守隔离指南且未接种第二剂疫苗的学生阳性率较高。
本研究为校内检测策略的有效性以及学生因宿舍居住情况、对隔离指南的遵守情况和疫苗接种情况不同而存在不同感染易感性提供了科学证据。
