[Demand-driven communication strategy of the Federal Centre for Health Education (BZgA) during the COVID-19 pandemic].

With the declaration of a pandemic situation of national significance by the German Bundestag, the Federal Centre for Health Education (BZgA) is fulfilling its task of providing information for understanding the pandemic situation and implementing the necessary protective measures in a clear manner throughout Germany within the framework of the adapted National Pandemic Plan COVID-19. The BZgA targets its information according to the needs of specific groups and actively involves multipliers.In order to incorporate the perspectives of the population as well as those of prevention and health promotion professionals into the services developed by the BZgA, given the particularly initial low level of knowledge in the population, various methods and data sources were used: the COVID-19 Snapshot Monitoring (COSMO) population survey, the monitoring of citizens' enquiries via telephone and e‑mail to the BZgA, surveys of counselling professionals from nationwide telephone and online counselling centres, surveys of health professionals in early help (NZFH) and interdisciplinary practice expert hearings. Beyond providing pure information, practical and everyday offers should be developed and provided according to WHO guidelines and evidence-based criteria of effective communication in order to support the competences for a gradual adaptation to a "new normality".The paper describes the data-based and evidence-informed development process of communication content and offers, their dissemination via existing websites and channels for other topics as well as their integration into the new online platform www.zusammengegencorona.de . This demonstrates how demand-driven and target group-specific communication offers can be implemented beyond the classic and proven campaign appearance.
