ABSTRACT:
In this paper, deterministic and stochastic models for schistosomiasis
involving four sub-populations are developed. Conditions are given under which
system exhibits thresholds behavior. The disease-free equilibrium is globally asymptotically
stable if R0 and the unique endemic
equilibrium is globally asymptotically stable when R0 >1. The populations are computationally simulated under various
conditions. Comparisons are made between the deterministic and the stochastic
model.
