Model predicts repercussions of lifting quarantine

Three quarantine lengths and outcomes

New interdisciplinary research from Washington University in St. Louis — carried out by an electrical and systems engineer and a biomedical engineer from the McKelvey School of Engineering and a health care economist from the Olin Business School — outlines the effects on the economy and health outcomes of three distinct quarantine scenarios.

Their model indicates that, of the scenarios they consider, keeping a strict self-quarantine policy for seniors until the number of new infections is drastically reduced, while gradually loosening the policy for the rest of the population, will lead to the best economic and health outcomes.

The goal is to quantify and mitigate the impact of the current pandemic

According to Arye Nehorai, the Eugene and Martha Lohman Professor of Electrical Engineering in the Preston M. Green Department of Electrical & Systems Engineering, the goal is to quantify and mitigate the impact of the current pandemic.

Taking some time off his main research, Uri Goldsztejn, a PhD candidate in biomedical engineering in the McDonnell International Scholars Academy, was a co-author and contributed to the scientific community trying to mitigate the impact of the current pandemic by developing the mathematical modeling study regarding large scale quarantine policies.

The McDonnell International Scholars Academy has a dual mission. First, they recruit top scholars from partner universities, the U.S. and international universities across the globe, and mentor them as they pursue graduate and professional degrees at Washington University, preparing them to become future global leaders. They pursue doctoral and professional master’s degrees in architecture, business, engineering, law, medicine, neuroscience, sociology, or any of the 120+ academic programs offered. Second, they leverage the Academy’s international partnership network to incubate new ideas and foster collaborative research across countries and disciplines.
