Epidemiological, Clinical and Viral Genomic Features of Influenza Virus Infections Among Pilgrims During the Grand Magal of Touba Over 7 Years (2018-2024).
Article in Journal of medical virology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Large international gatherings such as the Grand Magal of Touba in Senegal may favor influenza A/B virus (IABV) transmission. We analyzed IABV genomes from human samples collected during the event in 2018-2024. Next-generation sequencing was performed for 190 qPCR-positive nasopharyngeal samples. Bioinformatic analyzes were performed using MAFFT v7.505, IQ-TREE v2.2.0, iTOL, Nextclade, and PREDAV-FluA. 106 (55.8%) complete genomes were obtained, including 99 type A and 7 type B. IAV genomes were classified as A/H3N2 (N = 48) and A/H1N1 (N = 43), based on hemagglutinin/neuraminidase-encoding segments. A/H3N2 was not detected in 2021 and 2023; A/H1N1 was only detected in 2018, 2021 and 2023. Phylogenies classified A/H3N2 and A/H1N1 into distinct clades varying from 1 year to the next. A single A/H1N1 sequences was predicted to be antigenic divergence from the vaccine strain concomitantly used. All IBV genomes (clades V1A.3a or V1A.3a.2) were from 2020. Some IABV genomes from the GMT were clustered together while the most similar genomes from databases were from Senegal, Subsaharan Africa or other countries. Present data describes the circulation of IABV during the GMT over time in the population studied here shedding light on the viral dynamics in such setting of mass gathering.
