Prevalence of Plasmodium Species Using Rapid Diagnostic Tests in Cameroon: First-Year Data From Routine Malaria Surveillance.

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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMalaria remains a major public health concern in Cameroon. Although Plasmodium falciparum is the predominant parasite, the prevalence of other Plasmodium species remains poorly documented due to the absence of a formal surveillance system. This study is aimed at assessing the prevalence of Plasmodium species through routine malaria surveillance using P.f/Pan rapid diagnostic tests (RDTs).
methodsA nationwide malaria surveillance program was conducted over 1 year (January-December 2024), covering health facilities across all regions and levels of care. Malaria cases were diagnosed using P.f/Pan RDTs, which detect P. falciparum and non-falciparum infections but cannot reliably differentiate individual non-falciparum species. Data were systematically compiled through the National Health Information System and analysed to determine the prevalence and distribution of Plasmodium species across regions.
resultsOf the 3,843,507 individuals tested, 43% were malaria-positive. P. falciparum monoinfection accounted for 82% of cases, mixed infections (P. falciparum + Pan) for 15%, and Pan infection for 3%. Regional analysis showed the highest prevalence of P. falciparum monoinfection in the Far North region (92.1%), followed by the North (85.7%), Central (82.5%), West (81.7%), and East (80.6%) regions. Seasonal variations revealed a peak in positive cases between June and July, whereas mixed and Pan infections remained consistently low.
conclusionsFindings confirm the presence of non-falciparum and mixed infections beyond P. falciparum. However, P.f/Pan RDTs have inherent limitations in species differentiation, underscoring the need for molecular techniques to improve species-specific identification. Strengthening malaria genomic surveillance, including monitoring of Plasmodium species diversity and HRP2/3 gene deletions that affect RDT performance, will be critical to enhance routine surveillance and guide effective malaria control strategies in Cameroon.
