Analysis of the spatial and temporal distribution of the Dengue virus (2006-2017), Zika (2015-2017) and Chikungunya (2014-2017) in Colombia

Abstract

Objective: to describe the spatial and temporal distribution of dengue, zika and Chikungunya viruses in Colombia and to identify clusters at spatial, temporal and space-temporal levels. Methods: A descriptive study was developed about the space and time distribution of the Dengue virus (2006-2017), Zika (2015-2017) and Chikungunya (2014-2017) in Colombia, using principles of spatial statistics, namely the spatial data exploratory analysis. Results: Areas of Colombia were identified where there is a higher density and prevalence of cases and were analyzed 1124 municipalities for each event (cases of Dengue, Zika and Chikungunya). Significant clusters (P<0.05) were proven in spatial, temporal and space-temporal analysis, in the south-western zone of the Andean region and in the Orinoquia region. Conclusions: Two conglomerates were confirmed for the Dengue, Zika and Chikungunya events, that could be established as areas of higher risk of co-infection.
