Chapitre IIFigure 3: Impact of transmission route removal in the model which involves d<strong>en</strong>sitydep<strong>en</strong>d<strong>en</strong>tand water­borne transmission. Removal of water­borne transmission ( ω =0) leadsto a lower disease preval<strong>en</strong>ce with a peak in May. Removal of d<strong>en</strong>sity­dep<strong>en</strong>d<strong>en</strong>ttransmission ( β =0) leads to a higher disease persist<strong>en</strong>ce than with d<strong>en</strong>sity­dep<strong>en</strong>d<strong>en</strong>ttransmission only. Water­borne transmission in isolation leads to similar dynamic, but lessamplified, as those observed for the model involving both transmission routes (water­borne +d<strong>en</strong>sity dep<strong>en</strong>d<strong>en</strong>t transmission).82
