Epidemiological profile of imported malaria cases in Colombia

Abstract

Despite the significant progress made in reducing morbidity and mortality in recent years, malaria remains a critical global health challenge. In Colombia, we are working towards eliminating malaria to achieve zero indigenous cases of human malaria. In this effort, it is also essential to understand the epidemiological profile of imported cases. This study aimed to determine the epidemiological situation of imported malaria cases in Colombia from 2007 to 2020. An observational, descriptive, and retrospective study used secondary sources for data analysis. A total of 7,583 imported malaria cases (0.8% of total burden) were recorded. 85% (6,507/7,583) were caused by Plasmodium vivax, and 89% (6,772/7,583) were imported from Venezuela. Imported malaria trend varied, contributing minimally to the national burden. Venezuela was identified as the main source of imported cases. These findings will contribute to improving disease surveillance and preventing the reintroduction of malaria in areas undergoing elimination.
