YUANG San-ling, Han Li-tao, MA Zhi-en (Faculty of Science. Xi'an Jiaotong University, Shanxi Xi'an 710049 China)  
An SEIRS model having infectious force in the latent period is discussed in this paper, the conditions and threshold to the existence of various equilibriums are established. By means of linearing and Lyapunov-Lassel invariant set theorem, we obtained the stable results of various equilibriums. The together influence of the latent period and infected period to the disease is exposed.
