SARS-CoV-2 risk taxation model and validation based on large scale Dutch test-events

Abstract

AbstractIn response to the outbreak of SARS-CoV-2 many governments decided in 2020 to impose lockdowns on societies. Although the package of measures which constitute such lockdowns differs between countries, it is a general rule that contacts between people, and especially in large groups of people, are avoided or prohibited. The main reasoning behind these measures is preventing that healthcare systems become overloaded. As of 2021 vaccines against SARS-CoV-are available, but these do not guarantee 100% risk reduction and it will take a while for the world to reach a sufficient immune status. This raises the question whether and under which conditions events like theater shows, conferences, professional sports events, concerts and festivals can be organized. The current paper presents a COVID-19 Risk taxation method for (large scale) events. This method can be applied to events to define an alternative package of measures replacing generic social distancing.
