Abstract

Background: The factors of why some people get SARS-CoV-2 and others do not, after a primary case in families remains questionable. Objective: To analyze some of the possible risk factors for contracting COVID-19 within families after there is a primary case. Methodology: An observational, longitudinal and prospective study to analyze data of variables considered possible risk factors collected of 132 people in 39 families with at least one polymerase chain reaction (PCR) confirmed COVID-19 primary case, was conducted from March 15 to December 15, 2020, in a center of general medicine in Toledo (Spain). The Relative Risk (Incidence among the exposed population / Incidence among the population not exposed) for possible risk factors as predictors of secondary transmission were calculated. Results: 39 families with 92 people were included with a primary case, of which 70 were sick (PCR positive) and 22 were healthy (PCR negative and asymptomatic). Age
