News Release 11-Aug-2020

In the USA, where the curve of infections has not yet flattened since the beginning of the pandemic, 158,000 people have died from Covid-19 already. And despite the choice by all US states to gradually ease lockdown from late May onwards to save the economy, 14 million Americans have lost their job, while the economic output in the second quarter of 2020 dropped by 9.5%. To help entrepreneurs decide on how they can safely reopen their business, mathematicians and statisticians here develop a model for the spread of infections within companies and the economic payoff of safety measures. Their findings are published today in Frontiers in Applied Mathematics and Statistics.

The authors show mathematically that, under a wide range of parameters, reopening your business will only be feasible if at least these safety measures are adopted: wearing goggles, gloves, and masks (when employees aren't alone); frequent hand washing; routine sanitation of the workfloor; social distancing; monitoring body temperature; and quarantine of exposed and sick employees. These measures won't only control the spread of Covid-19 within the company, but also increase your net profit under the assumptions of the model.
"We show that a business entity may stand a good opportunity to generate positive net profit after reopening only if necessary protection measures are strictly implemented," warns Miao. "It is also very important to monitor the number of infections through virus testing and contact tracing, especially at the early stage of reopening."
