Figure 4. — Relative contribution of different disease states to visceral leishmaniasis (VL) transmission over time during the World Health Organization–recommended interventions. In model E0 (left), only symptomatic individuals (VL and post-kala-azar dermal leishmaniasis [PKDL]) contribute to transmission. In model E1 (right), asymptomatic individuals are the main contributors to transmission. Both graphs are for a 10 per 10000 persons per year precontrol endemicity setting with 5-year attack phase followed by the consolidation phase. Assumptions: 2.5% of treated VL cases develop PKDL, PKDL lasts for 5 years on average, and PKDL cases are half as infectious as active VL cases. Supplementary Figure 3 includes the relative contribution of different disease states for all 4 models.
