摘要
建立具有不同染病者的SIJR流行病模型,得到疾病消除与持续的全局渐近稳定性和疾病消除与否的基本再生数R0。当考虑连续接种时,即使R0>1,只要接种率大于u(R0-1),疾病就会消除。
SIJR epidemic disease model with different infections was established.The global asymptotic stability of disease elimination and sustainable was got,and the basic reproductive number R0 which decide whether or not the disease eliminated was obtained.Considering continuous vaccination,even if R0〉1,as long as the vaccination rate was greater than u(R0-1),the diseases would be eliminated.
