Fatemeh Zarei, Saman Moghimi-Araghi, Fakhteh Ghanbarnejad

摘要:

在本文中,我们介绍了一个一般的框架,合作SIR动力学的共同感染。我们首先解析求解CGCG模型[1],然后在对称场景下求解广义模型。我们计算转换点,顺序参数,即感染主机的总数。我们还分析了两个合作的SIR动力学存在鞍结分岔,并且过渡是混合的。此外,我们还研究了对称解在初始扰动下稳定的条件。然后,我们研究了参数的非对称情况。一种病原体与另一种病原体的原发和继发感染率的不对称性越大,可以导致感染宿主越少,流行阈值越高,并且连续转换。我们的模型和结果的合并感染与超级感染[2]可以打开一条道路,模型疾病生态学。

英文摘要:

In this paper, we introduce a general framework for co-infection as cooperative SIR dynamics. We first solve analytically CGCG model [1] and then the generalized model in symmetric scenarios. We calculate transition points, order parameter, i.e. total number of infected hosts. Also we show analytically there is a saddle-node bifurcation for two cooperative SIR dynamics and the transition is hybrid. Moreover, we investigate where symmetric solution is stable for initial fluctuations. Then we study asymmetric cases of parameters. The more asymmetry, for the primary and secondary infection rates of one pathogen in comparison to the other pathogen, can lead to the less infected hosts, the higher epidemic threshold and continuous transitions. Our model and results for co-infection in combination with super-infection [2] can open a road to model disease ecology.
