COVID-19传播的动力学:来自黎巴嫩的证据

The Dynamics of COVID-19 spread: Evidence from Lebanon

Omar El Deeb, Maya Jalloul

摘要:

我们采用两种不同的方法来探索2019冠状病毒病(COVID-19)在黎巴嫩的传播:STEIR模型,这是一种经过修改的SEIR模型,考虑了旅行的影响,以及重复迭代模型。我们拟合了自首例确诊病例至2020年6月底的每日可用数据,并预测了与不同级别的社交距离措施和旅行流入相关的可能传染情况。我们确定在黎巴嫩的初始生殖传播率和所有随后的动态。在重复迭代(RI)模型中,我们利用现有的数据,目前感染的人预测未来的感染情况下,几种可能的传染。在这两个模型中,我们的结果表明,更严厉的缓解措施将减缓疾病的传播。另一方面,正如STEIR所揭示的那样,目前放松措施和部分恢复国际航班将引发第二次感染爆发,严重程度取决于放松的程度。我们建议机构和公众对缓解措施作出强有力的承诺,以避免不受控制的传播。

英文摘要:

We explore the spread of the Coronavirus disease 2019 (COVID-19) in Lebanon by adopting two different approaches: the STEIR model, which is a modified SEIR model accounting for the effect of travel, and a repeated iterations model. We fit available daily data since the first diagnosed case until the end of June 2020 and we forecast possible scenarios of contagion associated with different levels of social distancing measures and travel inflows. We determine the initial reproductive transmission rate in Lebanon and all subsequent dynamics. In the repeated iterations (RI) model we iterate the available data of currently infected people to forecast future infections under several possible scenarios of contagion. In both models, our results suggest that tougher mitigation measures would slow down the spread of the disease. On the other hand, the current relaxation of measures and partial resumption of international flights, as the STEIR reveals, would trigger a second outbreak of infections, with severity depending on the extent of relaxation. We recommend strong institutional and public commitment to mitigation measures to avoid uncontrolled spread.
