Abstract:
We deployed the VANTAGE (VAN for Transmissible Agent Genomic Epidemiology) mobile system in Lviv, Ukraine, demonstrating end-to-end sequencing of dried blood spot samples within a clinic van usually serving de-occupied and frontline regions. HIV-1 pol sequences were obtained from 50% of samples, all subtype A6. Median time to 100× coverage was 38 min. Phylogenetic analysis revealed a local transmission cluster including a displaced person and the non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance mutation E138A, supporting real-time HIV genomic surveillance in humanitarian crises.
