ABSTRACT
Introduction: In the transmission of COVID-19 in Santiago de Cuba province, three epidemic outbreaks were observed between 2020 and 2021. Objective(s): To identify the differences between intra-and extra-domiciliary infections in three epidemic outbreaks of COVID-19 in Santiago de Cuba between March 2020 and May 2021. Method(s): A cross-sectional descriptive study of COVID-19 cases in the territory and period above mentioned was carried out, using the usual bivariate techniques of statistics and implicative statistical analysis, to a sample of 6408 cass that was chosen by simple random sampling from the database of confirmed cases. Result(s): Extra-domiciliary contagion was significantly higher than intra-domiciliary contagion without differences by sex, but according to age groups and municipalities within and between both groups. The predominance of older adults in intra-domiciliary contagion and of young adults in extra-domiciliary contagion was significant. Symptomatic patients prevailed in the intra-domiciliary;and, the asymptomatic, in the extra-domiciliary, without significant differences between both forms. Children under 20 years of age, older adults, asymptomatic and Mella municipality were the characteristics that were associated with intra-domiciliary contagion, while, with the extra-domiciliary were related symptomatic young adults. Conclusion(s): The forms of intra-and extra-domiciliary contagion were modulated according to the behavior of the people and the isolation of each age group. Extra-domiciliary predominated in intermediate ages of life, as an expression of the behavior mediated by their economic responsibility at home, while extreme ages, who remained at home to comply with isolation measures, were more prone to intra-domiciliary contagion.
