A Screening Program for SARS-CoV-2 among University of Hawai'i at Mānoa Residence Hall Students during the COVID-19...

The University of Hawai'i at Mānoa (UHM) created a COVID-19 pandemic team to collaborate, plan, and mitigate the spread of COVID-19 across the campus. The purpose of this study was to identify asymptomatic and pre-symptomatic cases of SARS-CoV-2 among unvaccinated UHM residence hall students during 3 distinct intervals (semesters) within the COVID-19 pandemic. Supervised self-administered nasal swab testing samples were collected from unvaccinated UHM residence hall students and sent to a clinical laboratory for COVID-19 RT-PCR testing to detect SARS-CoV-2. Positive cases were contacted and placed in isolation while contact tracing was initiated. The screening program performed 2219 tests on 725 unique persons with the identification of COVID-19 infections in 38 asymptomatic unvaccinated students and an additional 10 cases through contact tracing. A positive correlation existed between the screening program case numbers and the state of Hawai'i 7-day average positive cases as demonstrated with a Pearson coefficient of 0.79 and P<.001. The COVID-19 positivity rate was greater during Spring Semester 2022 compared to both Spring Semester 2021 (P<.001) and Fall Semester 2021 (P <.001). This program served as a component ofa larger strategy to mitigate the effects of the COVID-19 pandemic on the UHM campus. Additional benefits of the program included opportunities to increase COVID-19 awareness, enact health policy measures, evolve to meet changing pandemic demands, and maintain a safe UHM campus.
