TANDAZO, Víctor et al. Prevalencia de malaria en Aguarico, comunidad de la Amazonía ecuatoriana. Rev Eug Esp [online]. 2022, vol.16, n.1, pp.71-80. ISSN 2661-6742.  https://doi.org/10.37135/ee.04.13.08.

Objective. To determine the status of the prevalence of Plasmodium in febrile patients who attend the Franklin Tello Nuevo Rocafuerte Basic Hospital, Aguarico town, comparing the results obtained with data from other epidemiological studies in the same area, and places near the border with Peru. Methods. A descriptive, retrospective, observational study of prevalence was carried out. From 2011-2015 2,668 capillary blood samples were collected corresponding to 55.04% of the total population of the Aguarico town. The Thick Drop and Giemsa-stained smear technique was used to determine Plasmodium positivity. Results. The range of variation of the prevalence in the inhabitants of the investigated communities ranged between 2.38% and 28.57%, detecting a higher prevalence in males (50.56%). These findings are like previous studies carried out between 1992-1995, in the same Aguarico region. The Relative Risk (RR) is 1.36 and the Odds Ratio (OR) was 1.71, with the risk of developing the disease being greater in the positives. Conclusions. The research data confirm the presence of an autochthonous focus of malaria produced by Plasmodium vivax in the Ecuadorian Amazon rainforest, except for 2 cases of .. falciparum imported from Peru. The cases diagnosed clinically and using the thick gout technique were treated with antimalarial medication with excellent adherence to the medication.
