Malária incubada: a mixed methods analysis on knowledge and experiences on Plasmodium vivax and asymptomatic malaria infections in a hard-to-reach and mobile population in the Amazon.
Article in Malaria journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05540470 (Radical CUREfor MAlaria Among Highly Mobile and Hard-to-reach Populations in the Guyanese Shield), which is not on this map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundAs the Americas move towards malaria elimination, its circulation is increasingly concentrated in isolated communities with poor access to healthcare, and the silent human reservoir is a challenge (particularly for Plasmodium vivax). The deployment of tafenoquine for radical treatment is an important new asset. The CUREMA project evaluates a complex intervention aiming at malaria elimination in artisanal and small-scale gold mining (ASGM) communities of the Guiana Shield Region. A pre-intervention assessment was conducted to explore ASGM populations' knowledge and perceptions of asymptomatic Plasmodium carriage and P. vivax malaria.
methodsThe target population was the ASGM community working across Suriname, French Guiana and Amapá (Brazil). Data was collected in 2022 in ASGM cross-border staging areas, during the CUREMA pre-intervention qualitative and quantitative (cross-sectional) surveys. This analysis explores knowledge, experiences and representations on asymptomatic plasmodial carriage, recurrences and P. vivax infections.
resultsThe qualitative survey included 25 semi-structured interviews, 14 group interviews and 38 informal conversations. The quantitative survey included 539 participants, mostly men (73.5%), with a median age of 38 years. Almost all the participants recognized mosquitoes as vectors of malaria, and a fraction recognized a microorganism as the causative agent of the disease. Awareness of asymptomatic forms of the disease ("malária incubada") and of risk of recurrences was common, and they were generally considered to be the result of inadequate treatment. Most participants could identify different types of malaria, but knowledge about P. vivax characteristics and radical treatment was limited.
conclusionsUnderstanding the interpretation of the disease by affected communities is essential to develop context-specific strategies and for enhancing acceptability and effectiveness of malaria elimination efforts. Trial registration NCT05540470 on clinical trials.
