From: Modelling the impact of ivermectin on River Blindness and its burden of morbidity and mortality in African Savannah: EpiOncho projections

Parameters

Definition

Microfilaricidal effect

The increase in microfilarial mortality.

Anti-fertility effect

The temporary reduction in the production of live microfilariae by adult female worms (also known as embryostatic effect).

Anti-macrofilarial effect

The long-term, cumulative adverse effect on adult worms due to prolonged exposure of the parasites to the drug (represented in the model as a per dose reduction in the per capita rate of microfilarial production by adult female worms).
