报告摘要：The global threshold dynamics of an epidemic model of SIQS type in environments with fluctuations are characterized, where the quarantine class are explicitly involved. Criteria are established for the permanence and extinction of the infective in environments with time oscillations. In particular, an environment which varies periodically in time is further considered. The global threshold dynamic scenarios (i..e, the existence and global asymptotic stability of the disease-free periodic solution, the existence of the endemic periodic solution and the permanence of the infective) are completely characterized by the basic reproduction number defined by the spectral radius of an associated linear integral operator.
