摘要
考虑到迁入人群和当地人群对血吸虫病传播不同的影响,建立了血吸虫病在两类易感群体中传播的数学模型,讨论了系统的稳定性以及阈值.利用灵敏度分析研究两类易感人群初始值对阈值的影响,并通过数值模拟进行理论验证.
Considering the different impact of immigration and local population on the schistosomiasis transmission, this paper established a new model including two types of susceptible population. The stability and the threshold value were studied. Sensitivity analysis was conducted for the impact of the initial value of the two types of susceptibles on the threshold value. The theoretical results were confirmed by some numerical simulations.
