报告摘要：In order to control H7N9 avian influenza, a highly pathogenic zoonotic disease, many strategies have been adopted, such as poultry culling, the closure of live poultry markets (LPMs), the vaccination of poultry, and the treatment for humans. Due to the limitness of resource, it is of paramount significance to achieve the optimal control. An epidemic model incorporating the saturated culling rate is formulated to investigate the transmission mechanism of H7N9. The threshold dynamics and bifurcation analyses are well investigated. Furthermore, the problem of optimal control is explored in line with Pontryagin's Maximum Principle, with consideration given to the comprehensive measures. The numerical simulations suggest that the vaccination of poultry and the closure of LPMs are the two most economical and effective measures.
