Early or partial results. Treat as a signal, not a conclusion.
This is a descriptive genomic surveillance report documenting Rift Valley fever virus lineage C persistence in Rwanda from 2022–2025, inferred to represent sustained local circulation rather than repeated introductions. The finding is based on whole-genome sequencing analysis of livestock samples and supports the need for continuous One Health surveillance, but does not quantify transmission rates, clinical outcomes, or evaluate interventions.
Descriptive genomic surveillance study. Livestock samples from Rwanda experiencing recurrent Rift Valley fever virus outbreaks. Intervention: Genomic characterization using Nanopore sequencing and phylogenetic analysis. Rwanda.
RVFV outbreaks in Rwanda resulted from sustained local circulation of lineage C rather than repeated introductions Ongoing transmission likely driven by sporadic spillover events
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
This surveillance finding indicates that control strategies in Rwanda should focus on interrupting ongoing local transmission and spillover pathways rather than only preventing external introductions. However, the study does not evaluate specific interventions or quantify outbreak magnitude.
A descriptive genomic surveillance study without epidemiological outcomes, experimental design, or quantified transmission data; documents virus circulation pattern but does not measure clinical impact or intervention efficacy.

Rwanda has experienced recurrent Rift Valley fever virus outbreaks in the last decade. In this study, we investigated whether these outbreaks resulted from repeated introductions or sustained local circulation. We generated RVFV whole-genome sequences from livestock samples collected between 2022 and 2025 using Nanopore sequencing. Genomic analyses indicated the outbreaks resulted from sustained local circulation of lineage C rather than repeated introductions, suggesting ongoing transmission likely driven by sporadic spillover. This study underscores the importance of continuous genomic One Health surveillance in endemic settings.
