It is characterized by prolonged intermittent fever, anemia, splenomegaly, hepatomegaly, and skin darkening. VL is primarily endemic in regions, such as Brazil, East Africa, and India. However, Northern Xinjiang, which is located in northwestern China, is considered a low-incidence area for VL, contributing to its status as a neglected infectious disease. In this report, we present a case of VL caused by Leishmania donovani that was diagnosed using metagenomic next-generation sequencing (mNGS). This case underscores the diagnostic value of mNGS, particularly in regions with low incidence of VL.
