摘要
讨论了一类人禽传染病模型,其中禽类被病毒感染后人们采取措施治疗病禽.治疗有助于禽类的存活,但人们可能通过接触病禽而被感染.禽间的疾病传播服从饱和接触率函数,人与禽的接触服从线性接触率.完成了稳定性和持久性研究,且进行了数值模拟以评估治疗的效果和风险.
In this paper, a human-poultry eco-epidemiological model is investi- gated. Where, poultry is infected by bacteria, then people take measures to treat the infected individuals. The treatment contributes to the survival of poultry, but people may be infected through contact with the infected poultry. The spread of disease among poultry follows the saturation incidence function, the contact for human with poultry follows the linear contact rate. Stability and persistence are carried out, then numerical simulations are implemented to assess the effect and the risk of treatment.
