They say, "In view of the current developments surrounding Covid-19, Deutsche Messe AG, together with the exhibitors of HANNOVER MESSE, has decided to stage the world's leading industrial trade fair in a purely digital format next April."


In this time of heavily spreading COVID-19, I think this is a natural decision.

There is no more information now, so I watch out what will be going on.
