Screening for SARS-CoV-2 Infection in Students at the Medical University of Warsaw, Poland Between November 15 and December 10, 2021 Using a Single Lateral Flow Test, the Panbio™ COVID-19 Ag Rapid Test

BACKGROUND: Education was significantly affected by the coronavirus disease 2019 (COVID-19) pandemic, caused by the SARS-CoV-2 virus. Online learning affects the quality of learning as well as the mental health status of students. Regular screening for COVID-19 may be crucial to provide practical classes during the pandemic. The present study aimed to analyze the usefulness of rapid antigen tests for on-campus COVID-19 screening in real-life conditions at a medical university in Poland. MATERIAL/METHODS: This screening study was carried out among students attending practical classes at the Medical University of Warsaw, Poland between November 15 and December 10, 2021, during which a series of rapid antigen tests (Panbio™ COVID-19 Ag Rapid Test Device, nasal) were performed by healthcare professionals (nurses). Out of 104 student groups selected for the study (n=1847 students), 423 individuals from 63 student groups were tested at least once (22.9% response rate). A total of 2295 samples were collected. RESULTS: Among the participants, 3.4% (n=15) had positive test results. Out of 15 COVID-19 cases, 14 were vaccinated. At least 1 positive COVID-19 case was detected in 8 student groups. In 3 student groups, we observed ≥2 infections that occurred at intervals, which may suggest student-to-student SARS-CoV-2 transmission. CONCLUSIONS: This study produced real-world data from a COVID-19 screening study and confirmed the usefulness of the rapid antigen test (Panbio™ COVID-19 Ag Rapid Test Device nasal) for on-campus COVID-19 screening prior to practical classes. Maintaining a high percentage of participants is crucial to ensuring the effectiveness of on-campus COVID-19 screening.
