Dengue Virus Type 2 Genomic Sequences and Analysis for Africa, 1964-2024

414 full-length dengue virus serotype 2 (DENV-2) genomes compiled and analyzed to clarify its evolutionary history and transmission dynamics across Africa. The dataset was created by Muhammad Bashir Bello and last updated on 30 April 2026. It includes sequences from 1964 to 2024, with analysis focusing on phylogenetics, temporal dynamics, and phylogeography.

Use Cases

• Phylogenetic analysis of DENV-2 lineages based on the compiled genomic sequences.
• Temporal reconstruction of viral spread across Africa based on the described time-scaled phylogenies.
• Phylogeographic mapping of transmission hubs and pathways based on the discrete-trait analysis mentioned.
• Characterization of genetic variation in prM, E, and NS1 genes based on the described SNP analysis.

Strengths

• Contains 414 full-length DENV-2 genomes.
• Covers a 60-year time range from 1964 to 2024.
• Includes detailed methodological description for phylogenetic and phylogeographic analysis.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is small at 25.9 KB, indicating limited scope or highly summarized data.
• Data may reflect geographic and temporal bias inherent to the availability of sequenced genomes.
