(LONDON) — Organizers of the world’s biggest mobile technology fair are pulling the plug over worries about the viral outbreak from China. The annual Mobile World Congress show will no longer be held as planned in Barcelona, Spain, on Feb. 24-27. “Global concern regarding the coronavirus outbreak, travel concern and other circumstances, make it impossible for the GSMA to hold the event,” John Hoffman, head of the organizing body, said in a statement Wednesday. The decision comes after dozens of tech companies and wireless carriers dropped out, with the latest cancelations by Nokia, Vodafone, Deutsche Telekom and Britain’s BT on Wednesday.
