The study is designed to determine the use of delivering point of care, rapid diagnosis with rK39 and treatment with AmBisome single dose of 10 mg/kg when administrated in the Primary Health Center (PHC) settings with regard to operational feasibility, safety and final cure rate at 6 months after end of treatment. Point of care diagnosis and treatment (PCDT) at the PHC level would bring the best available interventions closer to the patients with visceral leishmaniasis (VL) whose villages are within several kilometers of the PHC. This would support the VL elimination program in the Indian subcontinent.
