Abstract

Background: The number and characteristics of asymptomatic SARS-CoV-2 infections remains questionable. The relationship between domestic and non-domestic contacts remains unclear. Also, some asymptomatic people who test positive for the virus may later develop COVID-19 symptoms. Objective: To compare in general medicine the characteristics of asymptomatic and symptomatic COVID-19 patients. Methodology: Retrospective cohort study of confirmed cases of COVID-19 (positive PCR), from March 15 to November 15, 2020, with asymptomatic patients (without any symptoms or any clinical suspicion of COVID -19, other than potential contact status, at time of test and in the 14 days after the follow-up period) and symptomatic patients (with 2 or more symptoms consistent with COVID -19). Results: 100 patients were included, 77 with symptoms. The prevalence of asymptomatic COVID-19 patients was 23%. Asymptomatic patients vs. symptomatic were younger (mean age of 33.9 vs. 43.9 years; p = .008451), they have more known previous contacts (87% vs. 56%; p
