Risikokommunikation bei der Eindämmung der COVID-19-Pandemie: Herausforderungen und Erfolg versprechende Ansätze

Risk communication plays a central role in public health emergencies: it must enable informed decisions, promote protective or life-sustaining behaviour, and maintain trust in public institutions. In addition, uncertainties in knowledge must be named transparently; irrational fears and rumours must be refuted. Success factors for risk communication are the participation of citizens as well as the continuous recording of risk perception and risk competence in population groups. The current COVID-19 (corona virus disease 2019) pandemic poses specific challenges for risk communication. The state of knowledge on many important aspects concerning COVID-19 was and is often uncertain or preliminary, e.g. on transmission, symptoms, long-term effects and immunity. Communication is characterised by scientific language and an array of figures and statistics, which can render the content difficult to understand. Alongside the official announcements and statements by experts, COVID-19 is widely communicated on social media, spreading misinformation and speculation; this “infodemic” can complicate risk communication. Various national and international scientific projects will help tailor risk communication on COVID-19 to target groups and thereby render it more effective. These projects include explorative studies on how people deal with COVID-19-related information; the COVID-19 Snapshot Monitoring (COSMO) project, a regularly conducted online survey on risk perception and protective behaviour; and an interdisciplinary qualitative study that compares the design, implementation and effectiveness of risk communication strategies in four countries.
