Risk factors for visceral Leishmaniasis among residents and migrants in Kafta-Humera, Ethiopia.

Background: Visceral leishmaniasis is a lethal parasitic disease transmitted by phlebotomine sand flies. The largest focus of VL in Ethiopia is located in the lowland region bordering Sudan, where the epidemiology is complicated by the presence of thousands of seasonal agricultural workers who live under precarious conditions.

Methodology/principal Findings: We conducted two parallel case-control studies to identify factors associated with VL risk in residents and migrants.
