I haven’t finished putting together my schedule for MWC Barcelona later this month, but my calendar for that trade show is already getting culled.

Three major tech firms–Ericsson, LG and Nvidia–have pulled out of the wireless industry’s global gathering, citing fears of the novel coronavirus. Nvidia is no key player in the industry, but LG remains significant to smartphones. And Ericsson not only has a major 5G-infrastructure business, its MWC exhibit has been a reliable source of a free lunch.

The rest of the show appears set to go on as usual, although with unusual precautions. ZTE announced last week that it will have senior executives attending the show quarantine themselves in Europe for two weeks beforehand and require all Barcelona-bound employees to have been symptom-free for 14 days prior. GSMA, the organization that runs MWC, said two weeks ago it will disinfect public areas frequently and advise everybody at the show to stick to a no-handshake rule and wash their hands frequently.

My calendar still has MWC on it, and that remains the case with other tech journalists I know–and whose judgment I trust. The show is still on and news and networking will still happen there, while the actual risk appears quite low in the context of MWC’s distance from China and the health screenings now imposed on the dwindling number of passengers from there.

But the risk is not zero, not with that many Chinese companies set to exhibit at MWC. I would like to think that they will all exercise the same care as ZTE. But I suppose prudence may require me to avoid an entire country’s exhibits… which, considering that China’s smartphone industry is already walled off from the West thanks to Google being a non-participant there, was already part of my MWC coverage plans.

And I will, of course, wash my hands frequently and not shake anybody else’s. I’m thinking that bowing slightly to strangers and exchanging fist-bumps with friends will be reasonable alternatives.
