Risk Analysis Methodologies

The prolonged and unpredictable use of travel measures during COVID-19 stemmed in part from a lack of agreed risk-based approaches across national governments. Most governments implemented travel measures in response to COVID-19 without providing evidence-informed rationales. Looking ahead, policymakers will be faced with the critical challenge of how to appropriately analyze the need to use travel measures when responding to future pathogens including new SARS-CoV-2 variants. To contribute to tools which support coordinated, evidence-informed decision-making in future, our research identifies and analyses different risk methodologies that countries have adopted on trade or travel measures in response to COVID-19.
