Companies based in Santa Clara county should avoid travel and postpone mass gatherings, the county recommended on Thursday. The recommendations come after six new cases of the novel coronavirus have been identified, bringing the total number of people confirmed to have the disease to 20.

The county’s guidance affects several major Silicon Valley employers. Apple is headquartered in Cupertino; Google in Mountain View; Tesla, in Palo Alto; Netflix, in Los Gatos; LinkedIn and Adobe, in San Jose. Other companies with offices in the area might be affected.

Guidance from the county include minimizing the number of people’working within arm’s length of one another’. Urging people to stay home if they’re sick, and spacing out start and end times of the workday for employees.

The recommendations are an attempt to slow the spread of the new coronavirus by limiting in-person contact. Many tech companies based in the area have already made their own attempts to curb the disease’s spread.
