The simultaneous presence of three distinct monkeypox virus lineages in a single geographic region creates unprecedented conditions for viral evolution and potential public health challenges. This genomic surveillance finding represents the first documented co-circulation of both endemic African clades and the globally spread lineage in the same population. Whole-genome sequencing revealed clade IIb lineage A.2.2—the strain responsible for the 2022 global outbreak—now established in the Republic of the Congo alongside native clades Ia and Ib that have circulated in Central and West Africa for decades. The convergence of these genetically diverse lineages in one location significantly elevates the theoretical risk of recombination events, where viruses could exchange genetic material to produce hybrid variants with unpredictable characteristics. Such recombination has precedent in other DNA viruses and could potentially alter transmission patterns, virulence, or immune escape properties. This finding underscores critical gaps in viral surveillance infrastructure across endemic regions, where limited genomic monitoring may have missed similar co-circulation events. The detection required sophisticated phylogenetic analysis that many resource-limited settings cannot routinely perform. From a global health preparedness perspective, this development highlights the urgent need for enhanced genomic surveillance networks in Central Africa, particularly given the region's role as the historical reservoir for monkeypox. While recombination remains hypothetical rather than observed, the molecular conditions now exist for such evolutionary events. The study's implications extend beyond monkeypox to broader principles of pandemic preparedness, demonstrating how global pathogen spread can create novel evolutionary pressures in endemic regions.
