Abstract

In this article we model two-strain dynamics of dengue transmission by both mosquitoes and humans with vertical transmission to larvae in the mosquito population. We include secondary infections, causing a severe form of disease. Mathematical analysis of proposed model is conducted - we study existence and local stability of equilibria of the system. While analysing the model, unusual properties emerged which lead us to implement its simplifications and obtain different results. Theoretical outcomes are accomplished with numerical simulations. They suggest that vertical transmission has a negligible impact on the dengue spread.

垂直传播双菌株宿主-媒介登革热模型的数学分析。
在这篇文章中,我们模拟了登革热由蚊子和人类垂直传播到蚊子种群幼虫的两株动力学。我们包括继发性感染,导致一种严重的疾病。对该模型进行了数学分析,研究了系统平衡点的存在性和局部稳定性。在分析模型时,出现了一些不寻常的性质,导致我们对其进行了简化,并得到了不同的结果。通过数值模拟验证了理论结果。他们认为垂直传播对登革热传播的影响可以忽略不计。
