Demographic, clinical-epidemiological and geospatial aspects of COVID-19 in Santiago de Cuba
Keywords:
COVID-19, Epidemia, Santiago de Cuba, Análisis demográfico, Clínico-epidemiológico, Geoespacial.Abstract
Background: Santiago de Cuba, like the rest of the Cuban provinces, was affected by COVID-19, although it is one of the territories with the lowest incidence of the disease.
Objective: to describe the demographic, clinical-epidemiological and geospatial aspects of COVID-19 in Santiago de Cuba.
Methods: an analytical observational study was carried out at the individual and population levels. At the individual level, the 49 confirmed cases of COVID-19 in the province are used as the study population. The frequency and distribution of cases were estimated, as well as hypothesis tests, with a 5% significance, to discover the differences between them. To analyze the geospatial aspect, the geo-referenced data from all the popular councils into which the province is divided were used as area data, the number of cases by territory and as aggregation units of the information. The exploratory analysis of the spatial data was performed, the spatial autocorrelation was estimated by popular councils, using the Moran global index I, and the formation of clusters was visualized using the local G* statistic from Getis-Ord.
Results: the frequency and distribution of the demographic, clinical and epidemiological characteristics were obtained, as well as the formation of spatial groupings by popular councils according to the number of COVID-19 cases and their significance.
Conclusions: the municipality of Santiago de Cuba marked the differences at the population level in the epidemic of this province. On the other hand, at an individual level, differences were observed between the confirmed cases in some demographic aspects, but not in the clinical or epidemiological ones.
DeCS: CORONAVIRUS INFECTIONS/epidemiology; EPIDEMICS; DEMOGRAPHIC DATA; GEOGRAPHIC INFORMATION SYSTEMS; OBSERVATIONAL STUDY.
