Genomic surveillance in Morocco tracks SARS-CoV-2 variant shift from Alpha to Omicron sublineage JN1.
Article in Npj viruses, 2025. 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
The persistent evolution of SARS-CoV-2 highlights the crucial role of genomic surveillance in tracking emerging variants and guiding public health interventions. We performed whole-genome sequencing on 235 SARS-CoV-2-positive samples collected across Morocco between 2021 and 2024 to characterize viral evolution and variant dynamics. Our analysis revealed a temporal shift in variant prevalence that paralleled global trends: initial co-circulation of Alpha and Delta variants, followed by complete replacement by Omicron and its sub-lineages in 2022. Phylogenetic reconstruction identified key mutations associated with enhanced immune evasion and transmissibility, demonstrating the virus's adaptive capacity. These findings underscore the critical importance of sustained genomic surveillance for monitoring viral evolution, informing vaccine and therapeutic strategies, and guiding public health responses. Our results advocate for expanded collaborative surveillance networks to proactively address threats from SARS-CoV-2 and other betacoronaviruses.
