The Hannover Region Health Authority had strongly recommended that Deutsche Messe follow the advice of the Robert Koch Institute, which includes comprehensive measures to safeguard health when hosting major events. For instance, fever measuring stations at all entrances and not allowing people from risk areas or those who have had contact with people from risk areas to enter the exhibition centre. This would have entailed a comprehensive evaluation of all trade fair participants – from exhibitors and visitors to service providers, exhibit builders and catering companies.

Deutsche Messe concluded that it was unable to implement the proposed measures. In addition, their implementation would impair the staging of the event to such an extent that the event would not fulfil its purpose or would do so only with considerable restrictions for exhibitors and visitors.
