Abstract
Mpox is a zoonosis caused by the monkeypox virus. Here, we report Mali’s index Mpox case, which was clinically identified at the Mali-Guinea border by the national telemedicine centre and confirmed by PCR. The library prepared with NextGenPCR™ MPXV Sequencing Library Prep and sequenced on Minion MK1C revealed a genome length length of 177,122 bp with an average depth 1284.4x. The strain belonged to clade IIb G1 lineage and exhibited 85 mutations relative to NC_063383.1. To decipher genomic epidemiology, genomes ≥195 kb were retrieved from NCBI and aligned with MAFFT. Time-resolved phylogenetic reconstruction and ancestral trait inference were performed with TreeTime v0.11.4. Phylogeographic analysis revealed clustering with clade IIb (G.1 lineage) linked to the May 2025 outbreak in Sierra Leone.
