Organizers of the ITB travel trade fair in Berlin which is considered as the world's biggest, have cancelled next week's event in the German capital over coronavirus fears.

The fair was to open next Wednesday (March 4), but concerns grew over the viability of hosting huge numbers of visitors as Germany recorded a jump in the number of infected residents.

Christian Goeke, chairman of organizers Messe Berlin said "With more than 10,000 exhibitors from over 180 countries, ITB Berlin is of great importance for the global tourism industry. We take our responsibility for the security and the health of our guests, exhibitors and employees very seriously. It is with a heavy heart that we have to look at the necessary cancellation of the ITB Berlin 2020."
