Objective: In the fight against the pandemic, besides identifying and isolating symptomatic individuals, prevention of the spread of the disease in asymptomatic individuals is also essential. This study aimed to determine SARS-CoV-2 positivity rates in asymptomatic patients presenting for COVID-19 screening and to determine the relationship between COVID-19 vaccination status and asymptomatic infection.

Methods: The results of SARS-CoV-2 PCR samples studied in the Microbiology Laboratory of Ağrı İbrahim Çeçen University Training and Research Hospital between September 2021 and December 2021 were retrospectively scanned. The relationship between patients’ demographic characteristics, symptom status, COVID-19 vaccination status, asymptomatic status, and COVID-19 vaccination status were evaluated.

Results: A total of 860 patients with positive SARS-CoV-2 PCR were included in the study. The mean age of the patients included in the study was 35.0±15.12, 54% were female and 46% were male. While 60% of the patients were vaccinated with at least one dose, 41% were not vaccinated. When the patients were divided into two groups: those vaccinated with at least one dose and those who had never been vaccinated, the mean age of the unvaccinated group was significantly lower. There was no significant difference between gender and vaccination status. The rate of asymptomatic positivity in the vaccinated group was significantly higher compared to the unvaccinated group.

Conclusion: In our study, the symptomatic positivity rate was found to be 70.2% and the asymptomatic positivity rate was significantly higher in the vaccinated group than in the unvaccinated group.
