With conferences canceled, factory schedules disrupted and workers urged to work from home, the coronavirus has quickly left its mark on an industry that typically runs like clockwork with an annual calendar of investor-friendly projections, product releases and large glossy stage shows.

At the time of writing, COVID-19, a disease caused by the new form of virus, has been linked to more than 3,100 deaths, 91,000 infections globally, and is rising daily.

The Centers for Disease Control and Prevention says the illness easily spreads person-to-person and via contact with infected surfaces or objects. There is no known cure.

For prevention tactics, the CDC says online: “Community-based interventions such as school dismissals, event cancellations, social distancing, and creating employee plans to work remotely can help slow the spread of COVID-19. Individuals can practice everyday prevention measures like frequent hand washing, staying home when sick, and covering coughs and sneezes.”

Broadly, the technology industry has been listening closely, with massive yearly conferences including Mobile World Congress (MWC) and the Geneva Motor Show already being scrapped.

Some firms warn that product output is likely to be impacted, while some tech employees have already tested positive for the virus. With the reach of COVID-19 growing by the day, the true impact will not be clear for some time. But for now, here’s how the biggest tech companies have been hit so far.
