The mobile industry’s largest and most important annual gathering, MWC Barcelona, is starting to fall apart due to concerns over potential exposure to the coronavirus. The virus was first detected about six weeks ago in Wuhan, China, and has since spread to more than 40,650 people and claimed at least 910 lives, according to the latest figures provided by health officials.

GSMA, the MWC Barcelona event organizer, claims the event will still get underway in less than two weeks, but adds that it is continuing to monitor the situation and will adapt its plans accordingly. “We are contending with a constantly evolving situation that will require fast adaptability,” GSMA President John Hoffman wrote in a prepared statement over the weekend.

At least a dozen companies have pulled out of the event, citing concerns over the health and safety of employees and customers. The withdrawals, which began as a slow drip are quickly becoming a torrent that shows no signs of waning.

LG was the first major vendor to cancel plans for the event, but many others have followed in kind. Amazon, Ericsson, Nvidia, and Sony have also withdrawn from this year’s event in Barcelona, Spain. The five companies combine for a total market valuation of $1.34 trillion. Amazon is currently valued at $1.06 trillion alone.

When Ericsson, one of the world’s leading radio access network (RAN) vendors, withdrew from the event it appeared to put the entire event at risk. “The health and safety of our employees, customers, and other stakeholders are our highest priority,” Ericsson CEO Börje Ekholm wrote in a prepared statement. “It is very unfortunate, but we strongly believe the most responsible business decision is to withdraw our participation from this year’s event.”

Nvidia cancelled hours later and, as of this morning, Amazon, Sony, NTT DoCoMo, CommScope, Amdocs, Viavi Solutions, Umidigi, Coosea Group, and Panorama Software have canceled plans for the event. ZTE and TCL have canceled press conferences scheduled for MWC Barcelona but still plan to exhibit and hold meetings. Samsung has also reportedly scaled back plans for the event, but it hasn’t made its intentions public to date.

Many other companies with major presences at the show, which was expected to host 109,000 people, are still contemplating next steps. The list of potential no-shows includes major operators, RAN and software vendors, chipmakers, and cloud providers. Large U.S-based firms like AT&T, Microsoft, Verizon, Cisco, IBM, VMware, and Intel have yet to provide any updates.

A spokesperson for Nokia said the company is continuing to monitor the situation and will make further determinations as necessary. “As of now, we continue to plan to attend but the situation is fluid. We will make decisions based on the best interests and the health and safety of our employees and customers,” the spokesperson said.

The rapid unraveling of MWC Barcelona has also underscored and inflamed a growing chasm between Chinese-based technology companies and many other parts of the world. The coronavirus’ origins has put Chinese companies in an unfortunate position and those exhibitors have taken preventative measures to allay concerns. However, fears of exposure to the virus have reached the point of xenophobia in some instances.

GSMA has taken multiple steps to ensure the health and safety of attendees, but it’s unclear how much impact those moves will have on the show overall. Moreover, some of the more stringent requirements directed toward Chinese attendees could further ramp up unchecked fears and negatively impact the global stature of the event. MWC Barcelona has historically hosted about 5,000 visitors from China, representing roughly 5% of the total audience, according to GSMA.

The industry association has banned all travelers from the Hubei province, where the virus is most prevalent, and required all travelers who have visited China to prove they have been outside of the country for at least 14 days prior to the event. GSMA said “attendees will need to self-certify that they have not been in contact with anyone infected” and temperature screenings will be implemented.

For now, it says the show will go on.
