自我防护措施对疟疾传播动力学的影响
发布时间:2018-09-12 18:36
【摘要】:建立了一类具自我防护措施的疟疾模型,并探讨了人群的自我防护因素对疟疾传播的影响.模型构建中采用蚊帐使用率来反映对疟疾防护能力的大小,并结合基本再生数R_0,利用迭代法分析疟疾病毒的传播动力学特征.结果表明,在蚊帐使用率p满足一定条件的前提下,当R_01时,无病平衡点全局渐近稳定;当R_01时,地方病平衡点全局渐近稳定.
[Abstract]:A malaria model with self-protective measures was established and the effect of self-protective factors on malaria transmission was discussed. In the model construction, mosquito net utilization rate was used to reflect the magnitude of malaria protection ability, and combined with the number of basic regeneration R _ 0, the dynamic characteristics of malaria virus transmission were analyzed by iterative method. The results show that the disease-free equilibrium is globally asymptotically stable under the condition that the net utilization p satisfies certain conditions, and the endemic equilibrium point is globally asymptotically stable when R _ (01) is satisfied.
