预测COVID-19大流行爆发期间的医院需求

Forecasting hospital demand during COVID-19 pandemic outbreaks

Marcos A. Capistran, Antonio Capella, J. Andres Christen

摘要:

我们提出了一个分区SEIRD模型,旨在预测当前COVID-19爆发期间大都市地区的医院入住率。该模型以无症状和有症状感染者为特征,并附有详细的医院动态。我们明确的模型分支概率和非指数停留时间在每个潜伏和感染的隔间。使用入院确诊病例和死亡病例,我们推断出接触率和动力系统的初始条件,考虑断点来模拟封锁干预措施。我们的贝叶斯方法使我们能够及时产生医院需求的概率预测。该模型已被墨西哥联邦政府用于协助公共政策,并已被应用于该国70多个大都市区和32个州的分析。

英文摘要:

We present a compartmental SEIRD model aimed at forecasting hospital occupancy in metropolitan areas during the current COVID-19 outbreak. The model features asymptomatic and symptomatic infections with detailed hospital dynamics. We model explicitly branching probabilities and non exponential residence times in each latent and infected compartments. Using both hospital admittance confirmed cases and deaths we infer the contact rate and the initial conditions of the dynamical system, considering break points to model lockdown interventions. Our Bayesian approach allows us to produce timely probabilistic forecasts of hospital demand. The model has been used by the federal government of Mexico to assist public policy, and has been applied for the analysis of more than 70 metropolitan areas and the 32 states in the country.
