A schistosomiasis compartment model with incubation and its optimal control

摘要

A new mathematical model included an exposed compartment is established in consideration of incubation period of schistosoma in human body. The basic reproduction number is calculated to illustrate the threshold of disease outbreak. The existence of the disease free equilibrium and the endemic equilibrium are proved. Studies about stability behaviors of themodel are exploited. Moreover, control measure assessments are investigated in order to seek out effective control interventions for anti-schistosomiasis. Then, the corresponding optimal control problem according to the model is presented and solved. Theoretical analyses and numerical simulations induce several prevention and control strategies for anti-schistosomiasis. At last, a discussion is provided about our results and further work.
