The COVID-19 pandemic forced most Kansas schools to adopt remote or hybrid learning in 2020-2021. Wichita Collegiate School proceeded with an in-person teaching model. The purpose of this study was to determine if in-person learning can be done safely during the COVID-19 pandemic prior to vaccine use.
Wichita Collegiate is a private school located in Sedgwick County, Kansas. The study population included 671 students (grades 1 - 12) and 130 staff. The procedures implemented during the school year (August 19, 2020 - May 21, 2021) included: mandatory face coverings, six feet physical distancing, and daily temperature checks. A registered nurse performed contact tracing and executed quarantine requirements per the U.S. Centers for Disease Control and Prevention guidelines.
Over the study period, 487 students and staff were tested for COVID-19 and 18.5% (n = 90) were positive. Overall, students and staff rate of COVID-19 infection was lower than the expected rate when compared to the surrounding community of Sedgwick County. Thorough contract tracing of positive cases revealed that 2.2% (n = 2) individuals were likely exposed to COVID-19 at school.
This study suggested that transmission of COVID-19 was infrequent in a school setting with in-person attendance, even before widespread vaccine availability. By following public health guidelines and utilizing contact tracing, it was possible to limit the spread of COVID-19 during in-person learning. This has immediate implications for how schools safely returned to in-person learning in the post-vaccine era.
2020 - 2021年,新冠疫情迫使堪萨斯州的大多数学校采用远程或混合式学习模式。威奇托学院学校则采用了面对面教学模式。本研究的目的是确定在新冠疫情期间,在疫苗投入使用之前,面对面学习是否能够安全进行。
威奇托学院学校是位于堪萨斯州塞奇威克县的一所私立学校。研究对象包括671名学生(1 - 12年级)和130名教职员工。本学年(2020年8月19日至2021年5月21日)实施的措施包括:强制佩戴口罩、保持6英尺的身体距离以及每日体温检测。一名注册护士按照美国疾病控制与预防中心的指南进行接触者追踪并执行隔离要求。
在研究期间,487名学生和教职员工接受了新冠病毒检测,其中18.5%(n = 90)呈阳性。总体而言,与塞奇威克县周边社区相比,学生和教职员工的新冠病毒感染率低于预期。对阳性病例进行的全面接触者追踪显示,2.2%(n = 2)的人可能在学校接触到了新冠病毒。
本研究表明,即使在广泛接种疫苗之前,在面对面授课的学校环境中,新冠病毒的传播也并不常见。通过遵循公共卫生指南并利用接触者追踪,在面对面学习期间有可能限制新冠病毒的传播。这对于学校在疫苗接种后时代如何安全恢复面对面学习具有直接影响。
