During December 3, 2020-January 31, 2021, CDC, in collaboration with the University of Utah Health and Economic Recovery Outreach Project,* Utah Department of Health (UDOH), Salt Lake County Health Department, and one Salt Lake county school district, offered free, in-school, real-time reverse transcription-polymerase chain reaction (RT-PCR) saliva testing as part of a transmission investigation of SARS-CoV-2, the virus that causes COVID-19, in elementary school settings. School contacts of persons with laboratory-confirmed SARS-CoV-2 infection, including close contacts, were eligible to participate (1). Investigators approached parents or guardians of student contacts by telephone, and during January, using school phone lines to offer in-school specimen collection; the testing procedures were explained in the preferred language of the parent or guardian. Consent for participants was obtained via an electronic form sent by e-mail. Analyses examined participation (i.e., completing in-school specimen collection for SARS-CoV-2 testing) in relation to factors that were programmatically important or could influence likelihood of SARS-CoV-2 testing, including race, ethnicity, and SARS-CoV-2 incidence in the community (2). Crude prevalence ratios (PRs) were calculated using univariate log-binomial regression. This activity was reviewed by CDC and was conducted consistent with federal law and CDC policy.*.
在 2020 年 12 月 3 日至 2021 年 1 月 31 日期间，疾病预防控制中心与犹他大学健康与经济复苏外展项目、犹他州卫生部、盐湖县卫生局以及一个盐湖县学区合作，在小学环境中提供免费的校内实时逆转录-聚合酶链反应（RT-PCR）唾液检测，作为对导致 COVID-19 的 SARS-CoV-2 病毒传播调查的一部分。实验室确诊的 SARS-CoV-2 感染人员的学校接触者，包括密切接触者，有资格参加（1）。调查人员通过电话联系学生接触者的家长或监护人，并在 1 月份利用学校电话线提供校内标本采集；检测程序用家长或监护人的首选语言进行解释。通过电子邮件发送的电子表格获得参与者的同意。分析考察了与方案重要因素或可能影响 SARS-CoV-2 检测可能性相关的参与情况（即完成 SARS-CoV-2 检测的校内标本采集），包括种族、民族和社区中的 SARS-CoV-2 发病率（2）。使用单变量对数二项式回归计算粗患病率比（PR）。该活动经疾病预防控制中心审查，符合联邦法律和疾病预防控制中心政策。*。
