Abstract

COVID-19 is a constantly challenging global health issue due to its strong intensity, rapid mutation and high infectiousness. The new Delta and Omicron variants have triggered massive outbreaks worldwide. Even China, which has done a good job in outbreak prevention, is still heavily affected by the virus. The long-term fight against multiple COVID-19 outbreaks is ongoing. In this study, we propose an SEIQR model that considers the incubation period and quarantine measurement. We verified our model using actual outbreak data from four Chinese cities. Numerical simulations show that a five-day delay results in a double resurgence scale. Our model can be used as a tool to understand the spread of the virus quantitatively and provide a reference for policymaking accordingly.

新冠肺炎在中国当地社区死灰复燃的流行病模型
COVID-19因其强度大、突变快、传染性强,是一个不断挑战的全球卫生问题。新的德尔塔病毒和欧米克隆病毒变种在全球范围内引发了大规模爆发。即使是在疫情防控方面做得很好的中国,也仍然受到病毒的严重影响。抗击多起COVID-19疫情的长期斗争仍在继续。在本研究中,我们提出了一个考虑潜伏期和检疫措施的SEIQR模型。我们使用来自中国四个城市的实际疫情数据验证了我们的模型。数值模拟表明,5天的延迟会导致双复苏规模。我们的模型可以作为定量了解病毒传播的工具,并为相应的政策制定提供参考。
