Abstract

Introduction: SARS-CoV-2 infection constitutes a health problem of relevance.

Objective: To characterize epidemiologically the SARS-CoV-2 infection in the population belonging to the 19 de Abril Polyclinic.

Methods: A cross-sectional study was conducted with all patients diagnosed with SARS-CoV-2 infection in the period between January and April 2021. A total of 488 patients were diagnosed in the study period. The instantaneous reproductive number was estimated to assess the behaviour of the same.

Results: Female sex predominated with 54.5 %. The most represented age group was 50-59 with 19.7 %. The Plaza de la Revolución popular council had the most cases with 56.4%. Symptomatic patients were the most represented with 68.0%. The mean number of days in hospital was 8.5 ± 3.1 days. A significant difference was found between symptomatic and asymptomatic patients (MD: 0.76; 95 %CI: 0.034 to 1.56). Rt was estimated to behave homogeneously over the 120 days analysed, with the highest number of infections found between 02/3/2021 and 15/4/2021.

Conclusions: SARS-CoV-2 infection in the study population behaved similarly to that reported in other Cuban studies; however, a more in-depth design is needed to determine precisely the factors associated with longer hospital stay. The Rt behaved homogeneously and proved to be a useful tool for understanding the behaviour of an epidemic in real time.
