SARS-CoV-2的病毒繁殖提供了获得有利突变的机会,改变了病毒的传播性、疾病严重程度和/或允许逃避自然或疫苗来源的免疫。我们使用了三种数学模型:具有均匀混合的简约确定性模型;年龄结构模型;以及一个随机输入模型来研究潜在关注变量(VOCs)的影响。根据2021年5月英国的情况,我们发现假定的挥发性有机化合物的流行病学轨迹范围广泛,并取决于其传播性、免疫逃逸能力和假定的voc靶向疫苗的引入时间。我们证明,与常驻变异相比,具有显著传播优势的挥发性有机化合物,或具有免疫逃逸特性,可以产生与2020-2021年冬季相当的感染和住院浪潮。此外,一种传染性较弱但显示出部分免疫逃逸的变异可能引发一波感染,直到控制措施进一步放松才会暴露出来。
Viral reproduction of SARS-CoV-2 provides opportunities for the acquisition of advantageous mutations, altering viral transmissibility, disease severity, and/or allowing escape from natural or vaccine-derived immunity. We use three mathematical models: a parsimonious deterministic model with homogeneous mixing; an age-structured model; and a stochastic importation model to investigate the effect of potential variants of concern (VOCs). Calibrating to the situation in England in May 2021, we find epidemiological trajectories for putative VOCs are wide-ranging and dependent on their transmissibility, immune escape capability, and the introduction timing of a postulated VOC-targeted vaccine. We demonstrate that a VOC with a substantial transmission advantage over resident variants, or with immune escape properties, can generate a wave of infections and hospitalisations comparable to the winter 2020-2021 wave. Moreover, a variant that is less transmissible, but shows partial immune-escape could provoke a wave of infection that would not be revealed until control measures are further relaxed.
