Introduction

In early 2020 COVID-19 emerged, affecting every aspect of our day-to-day lives. With so little known, private businesses and policy makers moved quickly to manage the spread of the virus.

Delaware North partnered with some of the brightest minds in math and science to better understand the risk of COVID transmission. The result of that effort is the Safer Stadia model; a tool that helps analyze the relative risk of various activities and how different safety measures can help reduce risk.

The Model

The Safer Stadia model calculates the risk of each sub-activity based on time, proximity, and density/distance. The risk score of each sub-activity is summed up to calculate the total risk of an event as a numeric value. That “risk score” is then compared to the score of other activities, like eating in a restaurant, flying on a plane, or going to the store to help understand the relative risk level of the activity in question.

The research that serves as a backbone for this model is outlined in two papers (see the Questions & Resources below), both of which have completed peer review.
