【摘要】 研究了潜伏期和染病期均有传染力的SEIR传染病模型,在连续接种和治疗不同策略下平衡点的稳定性,获得了疾病消除的阈值.通过比较两种控制策略的有效性,说明接种比治疗更能有效地控制疾病,同时应用两种控制策略比单独应用一种更加有效.更多还原

【Abstract】 The stability of the equilirium on SEIR epidemic model with infectious force in latent period and infected period,under continues vaccination and treatment are studied,and the threshold conditions of disease dying out are obtained.By comparing the effectiveness under two control strategies,the results that vaccination in more effective than treatment,and using two strategies concurrently is superior to only one for eradicating the disease.更多还原
