Genomic diversity of SARS-CoV-2 carriage in a cohort of schoolchildren in Côte d'ivoire during COVID-19 pandemics: insights from pre-delta emergence.
Article in BMC infectious diseases, 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
backgroundAfter the first case of COVID-19 was reported in Côte d’Ivoire in March 2020, the virus spread significantly, with several epidemic waves. During a carriage study conducted from November 2020 to April 2021 to examine the oropharyngeal microbiome of school children, the presence of several other pathogens was investigated. This study characterised the diversity of SARS-CoV-2 detected in a cohort of school children in Côte d’Ivoire.
methodsOropharyngeal swabs from participants in Korhogo (n = 37) and Abidjan (n = 39) were analysed. RNA was extracted from the samples, followed by RT-qPCR detection of Coronaviruses. Sequencing was done on an Oxford Nanopore platform and data analysed in GISAID.
resultsOut of 445 samples collected, 15 (3.37%; 5 in Abidjan and 10 in Korhogo) tested positive for SARS-CoV-2 and were sequenced. Genomic coverage of over 70% was obtained for 12 genome sequences (80%). There was a significant difference in SARS-CoV-2 carriage over season per sampling visit (p < 0.05). The variants identified were of type Eta and Beta, including variant of concern (VOC) B.1.351 (6.7%), Variants of Interest (VOI) B.1.525 (60%) and other unclassified lineages B.1.1.318 (6.7%), A.19 (13,3%) and A.27 (13,3%). D614G mutation (n = 11, 73,33%) located on the S gene was the most common, followed by the T205I (n = 8, 53,33%) located on the N gene in this collection of genomes.
conclusionsThis study highlights the diversity of SARS-CoV-2 that circulated in a cohort of children in Côte d’Ivoire and reports carriage of the A.19 lineage, a variant which circulated more frequently in West Africa during the study period. CLINICAL TRIAL NUMBER: Not applicable.
