Response: At the onset of COVID-19, we developed a state-of-the-art epidemic progression model involving the susceptible, exposed, infected, and recovered (SEIR) dynamics, the age-stratified disease transmissibility, and the possible large-scale undocumented asymptomatic transmission of COVID-19 taking place in the US states. By informing our model with using epidemiological COVID-19 data for the US between March 19 and 28 – a period corresponding to the early stage of the epidemic when the impacts of social distancing on disease progression were yet to manifest – we investigated: “What is the medical cost benefit of implementing social distancing as the “only” non-pharmaceutical intervention policy to combat COVID-19 in the US?”
As part of this study, we investigated three social distancing strategies – indefinite, finite-duration, and intermittent – on age-stratified US population and benchmark its effectiveness in reducing the burden on hospital beds. (more…)
