Background: Malaria has been described among the most frequently reported parasitic diseases among
refugees and internally displaced populations (IDPs) in Africa and Asia. There is a lack of studies about it
in Latin America, including Colombia, the country with the highest number of IDPs in the world and also
endemic for malaria. Methods: This ecological study assessed incidence and its differences, on malaria
between general population and IDPs in Colombia and its departments (32) during 2007–2018.
Epidemiological data was collected from the National Surveillance System (SIVIGILA-SISPRO), retrieving
the codes for malaria in both populations. We estimated malaria incidence rates on both populations
(cases/100,000 pop), using reference population of the IDPs (official record of the Secretary of Social
Welfare) and the general population (from the national statistics institute, DANE). Incidence rates ratios
were calculated comparing both populations. Results: In general population, 713,012 cases of malaria
occurred (60.98% due to P. vivax) (1,521.49 cases/100,000 pop) while 17,170 among IDPs (66.03% due
to P. vivax) (6,330.30 cases/100,000 pop). Malaria was 4.16 times higher among IDPs than in general
population (p<0.05) (ranging from 2.30 times in 2007 to 16.24 in 2018). Malaria mortality rate among
general population was 0.43 deaths/100,000 pop and 1.84 among IDPs, being 4.28 times higher (p<0.05).
The difference by species, showed for Plasmodium malariae, 0.47 cases/100,000 pop in the general
population and 4.79 among the internally displaced (10.30 times higher). Discussion: This study showed
a significantly higher incidence of malaria among internally displaced persons, compared to the general
population in the same territories, including also higher occurrence of complicated disease. This has
relevant implications for screening, diagnosis and management among IDPs, especially in still highly
endemic areas.
