The suggested serial, cross-sectional study allows rapid and adaptive monitoring of focal variables over time, assessment of the relations between them, and randomisation of answer options where suitable. Among others, included variables relate to demographics, protective behaviours, knowledge, perceptions, and trust. Changes in risk perceptions or knowledge can be assessed over time; data on acceptance of new response measures can be made rapidly available; and misinformation or possible stigma can be identified as they emerge. Immediate data analysis by means of an automated data analysis website provides fast access to the results. WHO materials contain commented code (free R Studio online software) for data analysis and a website for rapid data presentation. The Insights Unit and Health Emergencies Programme in the WHO Regional Office for Europe are offering support to countries for implementation. National teams using the tool are urged to work in partner coalitions to discuss insights gained and implications for outbreak response interventions, policies and messages. Making results rapidly available to journalists is also suggested to support high quality and responsible media reporting. Journalists need timely knowledge about developing audience behaviour and habits to rapidly tailor information sharing and to develop narrative tools that encourage behaviour changes according to evidence from risk communication research.
