Rift Valley Fever Outbreak in Burundi: 1,739 Clinical Cases and Phylogenetic Analysis

1,739 clinical cases of Rift Valley fever were recorded during the first officially reported outbreak in Burundi, starting in May 2022. The dataset, created by Canésius Nkundwanayo, includes epidemiological field data and results from 100 samples screened via RT-PCR, with 36 positives. Phylogenetic analyses identified the causative strain as lineage C, sub-clade C.2.2, closely related to a 2022 Rwanda isolate.

Use Cases

• Modeling spatiotemporal distribution of disease cases based on farm location and date data.
• Identifying environmental risk factors for outbreaks based on associations with rainfall and temperature variables.
• Conducting phylogenetic analysis of viral strains based on genetic sequence data.
• Developing risk maps and decision support tools for disease management based on the epidemiological insights.

Strengths

• Includes a specific count of 1,739 recorded clinical cases.
• Provides results from 100 screened samples, with 36 positive RT-PCR tests.
• Data is associated with a specific, documented outbreak timeframe and geographic origin in Burundi.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Row count and column-level documentation are unknown; field semantics must be inferred after download.
• The dataset is very small at 5.9 KB, indicating limited scope.
• Data may reflect geographic and temporal bias specific to the 2022-2023 outbreak in Burundi.
