Acquired Immunity of a Schistosomiasis Transmission Model—Analysis of the Stabilizing Effects

A semi-stochastic model for schistosomiasis was developed based on the immune response built up by human host after elapsing a fixed period of timeLfrom the first infection, and on the parasite infection with multiple occurrences. cquired immunity and multiple parasite infections reproduced a great endemic stability for the disease and a high value for thebasic reproduction ratio.
