Source Tracing of Leishmania donovani in Emerging Foci of Visceral Leishmaniasis, Western Nepal

We sequenced Leishmania donovani genomes in blood samples collected in emerging foci of visceral leishmaniasis in western Nepal. We detected lineages very different from the preelimination main parasite population, including a new lineage and a rare one previously reported in eastern Nepal. Our findings underscore the need for genomic surveillance.
