Google’s top brass is urging workers to not panic over the coronavirus epidemic, reminding them that “millions of people and companies around the world are relying on us.”

That’s despite the fact that the search giant earlier this week canceled its annual developers conference, which was set to draw more than 7,000 attendees to its Mountain View, Calif., headquarters in mid-May.

“We know this is a very unsettling time for everyone,” Google chief executive Sundar Pichai wrote in a memo that was obtained by CNBC, which made a reference to a “colleague in Zurich” who was quarantined after testing positive for the virus last week.

“You’ve heard me talk about helpfulness in the context of moments big and small,” Pichai wrote. “This is one of those big moments.”

Google warned its 120,000 employees worldwide to “be prepared to work from home unexpectedly,” as well as to take their laptops home each night.

Financial chief Ruth Porat told employees they must stay home if they feel sick at all, warning that “it’s not okay to ‘tough it out,’” according to CNBC.

Pichai said Google is running a 24-hour command center to monitor the virus, according to the report, and implored employees to continue “working hard through a difficult time.”

The coronavirus has now infected more than 100,000 people around the world and recently appeared in the San Francisco Bay Area.
