论文摘要
我们提出了一个具有人口统计学的隔室数学模型,以实现Covid-19疾病的传播,也考虑了无症状的传染病。我们计算模型的基本生殖比率,并研究其局部和全球稳定性。我们基于意大利的情况以数值解决模型。我们提出了一个疫苗接种模型,并得出了在不完善疫苗的情况下防止感染扩散的阈值条件。
We present a compartmental mathematical model with demography for the spread of the COVID-19 disease, considering also asymptomatic infectious individuals. We compute the basic reproductive ratio of the model and study the local and global stability for it. We solve the model numerically based on the case of Italy. We propose a vaccination model and we derive threshold conditions for preventing infection spread in the case of imperfect vaccines.
