Abstract
Introduction: The SARS-CoV-2 pandemic challenged health systems and spurred the use of technologies and the understanding of spatial models for anticipating the epidemiological response. This study examined the spatiotemporal pattern of the spread of the first million cases of SARS-CoV-2 in Colombia.
Methodology: cross-sectional study, in which first and second order properties such as spatial intensity and covariance structure were considered, for the first million cases in the country, between March 3 and October 24, 2020. Data from the National Public Health Surveillance System (Sivigila), the DANE national population census and the Ministry of Transport's National Integrated Road Information System were used, cases were geocoded based on the address of residence and were analyzed using tools such as ArcGIS Pro and GVsig.
Results: The geographic distribution of cases was not random, concentrating mainly in metropolitan areas and districts with high population density and an interconnected national and departmental road network. Municipalities connected by national roads showed a higher incidence and mortality rate from SARS-CoV-2 compared to those connected by departmental roads or without this type of infrastructure. A significant association was found between population density and the incidence of cases and deaths.
