Characterizations of COVID-19 risk: review and suggestions for improvement of current practices

Abstract

Abstract To handle the risks related to coronavirus and the COVID-19 disease, governments worldwide have adopted different policies and strategies. These policies and strategies build on various approaches and methods to assess and convey the risks. This paper looks more closely into these approaches and methods. We review and discuss practices in four countries (Norway, the UK, the US and Sweden), focusing on the approaches, methods and models used to assess and describe the risks related to COVID-19. The main aims are to present some current thinking, reveal differences and suggest areas for improvement. The paper concludes that current practices can be enhanced by incorporating ideas and approaches from contemporary risk science, particularly in relation to how to treat uncertainties and reflect degrees of knowledge.
