Updating Anopheles funestus group members in Burkina Faso: species distribution and contribution to malaria transmission.
Article in Malaria journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
backgroundAnopheles funestus group and Anopheles gambiae complexes are among the most efficient malaria vectors in Africa, thriving in a variety of environments and well adapted to develop in semi-permanent and permanent water bodies. This study investigated the spatial distribution of the An. funestus group and their contribution to malaria transmission in Burkina Faso.
methodsAn entomological survey was conducted from October to December 2022 across 67 sites within the ecological zones of Burkina Faso (once a month); An. funestus was detected in 22 of these sites. Mosquitoes were collected using pyrethrum spray catches (PSC) and identified at the species complex level using morphological keys. A polymerase chain reaction (PCR) was performed for species identification among An. funestus group, blood meal sources and Plasmodium falciparum infection.
resultsA total of 617 members of the An. funestus group (45 males and 572 females) were collected across eight regions of Burkina Faso. Anopheles funestus s.s. was the most prevalent specie identified with a frequency of up to 95% (589/617). Most An. funestus s.s. were found in the Hauts-Bassins and the Sud-Ouest regions with 30% (177/589) and 55% (329/589), respectively. Hybrids between An. rivulorum and An. rivulorum-like were identified at a frequency of 3.57% (22/617). Additionally, results showed a high prevalence of zoophilic behaviour (64.3% of the blood source) in An. funestus. Plasmodium falciparum infection was detected in 5.76% (33/572) of the An. funestus s.l. populations with a frequency of 5.6% (32/572) and 0.174% (1/572) in An. funestus s.s. and An. rivulorum-like, respectively.
conclusionsThis study updates the distribution of the An. funestus group and its potential role in malaria transmission in Burkina Faso. It emphasizes the need to strengthen malaria vector surveillance and highlights the importance of incorporating An. funestus in developing innovative vector control interventions.
