As countries continue to struggle with an outbreak of the coronavirus that has infected over 100,000 people, tech giants like Google and Facebook are taking no chances.

An internal memo sent out to employees at Google and Facebook in New York on Tuesday includes a mandatory order to work from home for all North American employees.

Coronavirus symptoms are often indistinguishable from that of the seasonal flu, but in its most severe forms, the virus can cause fever, respiratory stress, and life-threatening pneumonia.

Symptoms range from mild to extremely severe depending on age, with seniors more likely to be impacted. It is spread through close proximity with an infected person – including asymptomatic carriers, who pose the greatest risk for spreading the infection.

This is a developing situation, more information will be provided as they become available.
