Prevalence of gestational malaria in Ecuador.

Introduction: Gestational malaria, defined as the presence of Plasmodium spp. in maternal peripheral blood or in the placenta, is considered an important public health problem in tropical and subtropical regions. Objective: To determine the frequency of gestational malaria cases diagnosed in Ecuador between 2015 and 2018. Materials and methods: We conducted a descriptive, retrospective, and cross-sectional study. Results: There were 46 cases of gestational malaria between 2015 and 2018: 25 caused by Plasmodium falciparum and 21 by Plasmodium vivax. The year with the most cases in this period was 2018. The age group most affected was 20 to 29 years old with 21 cases (46%). Prevalence was found to be highest in the second trimester of pregnancy with 17 cases (37%). A significant difference was only observed between cases per year and parasitic species. Conclusion: The prevalence of gestational malaria in Ecuador increased in the last five years. Therefore, it is important to inform pregnant women about preventive measures to avoid infection given its serious consequences both for the mother and her unborn child.
