LG, NVIDIA and Ericsson had already pulled out of the how in recent days. Samsung is also believed to have scaled back its presence, although it should still have a footprint at the show. Huawei and ZTE are still attending despite the outbreak having its roots in China, although they've told Chinese staff to isolate themselves and have pulled in European workers to cover for employees who can't go.
MWC has maintained that the trade show will go on, but it's implementing measures that include an outright ban on guests from China's Hubei province (where the outbreak began), temperature screening and proof that people who've been to China haven't been to the country in the past 14 days.
There's a lot of time to go between now and MWC's February 24th start, though, and the rapid-fire departures raise questions about what the show will be like by opening day. Although there are still major names left, there's now a greater temptation for them to bow out -- both because of the coronavirus and the absence of would-be business partners.
