Whole Genome Sequencing and Genetic Diversity of Respiratory Viruses Detected in Children With Acute Respiratory Infections: A One-Year Cross-Sectional Study in Senegal.
Article in Journal of medical virology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
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
Acute respiratory infections (ARI) are a health priority, especially in countries with limited resources. They are a major cause of morbidity and mortality, especially among children and the elderly. In Senegal, the endemic circulation of respiratory viruses other than influenza has been demonstrated. However, there is a paucity of data exploring the genetic diversity of these viruses based on whole-genome sequencing. In this study, we present data on the genetic diversity of respiratory viruses in children under 15 years old in Senegal, including an overview of the different pathogens detected. Between November 2022 and November 2023, we collected nasopharyngeal swabs from children seen in curative consultations for symptoms of acute respiratory infections. Of the 156 children included, 73.7% tested positive for at least one pathogen. The most frequently detected virus was rhinovirus (50.0%), followed by influenza B (41.6%) and human parainfluenza virus type 3 (7.6%). Combinations of rhinovirus/influenza B, human parainfluenza virus type 2/human parainfluenza virus type 4, and rhinovirus/influenza B/adenovirus were the most frequently identified. A statistically significant association was detected between some of the viruses detected. A high genetic diversity of respiratory viruses circulating in children was revealed. The strains were phylogenetically close to various strains circulating worldwide, suggesting a global circulation of respiratory viruses. Our study provides the first complete genome sequences of human parainfluenza viruses type 2, 3, 4 and human bocavirus from Senegal and thus contributes to the enrichment of international databases on sequences from Senegal and underlines the importance of sequencing in the dynamics of pathogen circulation.
