传染病通过间接接触传播的年龄结构SIR模型

Age structured SIR model for the spread of infectious diseases through indirect contacts

Manoj Kumar, Syed Abbas

摘要:

在这篇文章中,我们讨论了一个年龄结构的SIR模型,其中疾病不仅通过直接的人与人之间的接触传播,例如由于表面污染引起的感染,而且还可以通过间接接触传播。很明显,年龄在SARS病毒感染(包括COVID-19感染)中也起着至关重要的作用。我们制定我们的模型作为一个抽象的半线性柯西问题在适当的Banach空间,以显示解决方案的存在性,也显示存在的稳定状态。在这项工作中,假设人口是在一个人口统计的平稳状态,并表明,没有无病平衡点,只要有一个由于在环境中的间接接触传染。

英文摘要:

In this article, we discuss an age-structured SIR model in which disease not only spread through direct person to person contacts for e.g. infection due to surface contamination but it can also spread through indirect contacts. It is evident that age also plays a crucial role in SARS virus infection including COVID-19 infection. We formulate our model as an abstract semilinear Cauchy problem in an appropriate Banach space to show the existence of solution and also show the existence of steady states. It is assumed in this work that the population is in a demographic stationary state and show that there is no disease-free equilibrium point as long as there is a transmission of infection due to the indirect contacts in the environment.
