Introduction: Malaria is a serious public health problem, in 2015 there were about 214 million cases and 438,000 deaths worldwide. The department of the Amazon, reports higher indicators, where the cases with greater frequency are attributed to P. vivax 61.4%, followed by P. malariae 43.8% and lower percentage P. falciparum 11.8%. Objective: To determine the sociodemographic, clinical and housing factors that are associated with the risk of single and mixed infections by Plasmodium spp. in the municipalities of Leticia and Puerto Nariño. Methodology: Cross-sectional analytical observational study; database with secondary information, Analysis of sociodemographic, clinical and housing factors related to the prevalence of Plasmodium spp. Descriptive analysis, multiple correspondence analysis and binary logistic regression. Results: 50.8% of people with symptoms associated with malaria were men. Associations between zone 1 and mixed infection P. vivax and P. malariae (aOR 2.13: 1.33-3.42 95% CI); access to water service with mixed infections by P. malariae and P. falciparum (aOR 6.90: 4.98-8.28 95% CI) and triple infections (aOR 3.05: 1.20-7.74 95% CI), fever with triple infection (aOR 2.91 : 1.55-4.14 95% CI). Lower association parasitaemia (5,000 to 9,999 parasites / μL blood) in P. malariae and P. falciparum (ORaj 0.18: 0.35-0.93 95% CI). Conclusions: Public health actions and strategies should focus on housing variables and clinics, due to their relation to the risk of Plasmodium spp. the study evidences the underreporting of mixed infections by Plasmodium spp., which occur in endemic area for malaria of the Amazonian trapeze.
