Developments in Diagnosis of Visceral Leishmaniasis in the Elimination Era

الملخص EN

Visceral leishmaniasis (VL) is the most devastating parasitic infection worldwide causing high morbidity and mortality.

Clinical presentation of VL ranges from asymptomatic or subclinical infection to severe and complicated symptomatic disease.

A major challenge in the clinical management of VL is the weakness of health systems in disease endemic regions.

People affected by VL mostly present to primary health care centers (PHCs), often late in their therapeutic itinerary.

PHC physicians face a major challenge: they do not deal with a single disease issue but with patients presenting with complaints pointing to several diagnostic possibilities.

Risk exists when some patients having less clinical manifestations are misdiagnosed.

Therefore, field based accurate, sensitive, and cost effective rapid diagnostic tools that can detect disease in its mildest form are essential for effective control and reaching the goal of VL elimination.

In this review, we discuss the current status and challenges of various diagnostic tools for the diagnosis of VL and assess their application in resource poor settings.
