提取COVID-19大流行有效接触率

Extracting the effective contact rate of COVID-19 pandemic

Gaurav Goswami, Jayanti Prasad, Mansi Dhuria

摘要:

在没有任何可用疫苗或药物的情况下,我们正通过实施多项缓解措施来预防2019冠状病毒病(COVID-19)大流行的传播。必须有强有力和可靠的方法来评估这些措施的效力。在这项工作中,我们假设,在一个非常粗粒度的描述水平,所有的缓解措施的总体效果是,我们仍然可以描述流行病的传播使用最基本的易感-暴露-危险-删除($SEIR$)模型,但与“有效接触率”($β$),这是时间依赖性的。然后,我们使用人口中受感染者人数的时间序列数据来提取瞬时有效接触率,这是实施各种社会干预措施的结果。在评估缓解措施对COVID-19传播的影响时,该方法在不久的将来可能非常有用。

英文摘要:

In the absence of any available vaccines or drugs, prevention of the spread of Coronavirus Disease 2019 (COVID-19) pandemic is being achieved by putting many mitigation measures in place. It is indispensable to have robust and reliable ways of evaluating the effectiveness of these measures. In this work, we assume that, at a very coarse-grained level of description, the overall effect of all the mitigation measures is that we can still describe the spread of the pandemic using the most basic Susceptible-Exposed-Infectious-Removed ($SEIR$) model but with an "effective contact rate" ($β$) which is time-dependent. We then use the time series data of the number of infected individuals in the population to extract the instantaneous effective contact rate which is the result of various social interventions put in place. This approach has the potential to be significantly useful while evaluating the impact of mitigation measures on the spread of COVID-19 in near future.
