Burden and Epidemiology of Human Intestinal Infection in Colombia: A Systematic Review.

The genus is a unicellular protozoan able to parasitize both humans and animals. Cysts of can be found in soil samples, aquatic environments, food, and any surface that gets in contact with the feces of parasitized animals. The aim of this systematic review was to analyze the burden and epidemiology of infection in Colombia summarizing recent scientific reports and existing knowledge and to identify knowledge gaps that may be addressed in future investigations. This work follows the guidelines established by "Preferred Reporting Items for Systematic Reviews and Meta-Analyzes" (PRISMA). Published scientific literature from 1 January 2010 to 18 September 2022 was searched in six electronic scientific databases using the search terms: "" OR "Giardiasis" AND "Colombia". Twenty-three scientific articles were performed in 22 departments of Colombia at rural, urban, and a combination of rural and urban contexts. The prevalence of in the Colombian population was between 0.9 and 48.1% when the samples were analyzed with classical microscopy; the range of prevalence was even bigger (4.2-100%) when qPCR and nested PCR were used. The dominant assemblages found in Colombia were A and B, and most frequent subassemblages were AII, BIII, and BIV.
