Cisco has alerted its workforce that one of its employees was exposed to someone with a confirmed case of COVID-19, the disease caused by the coronavirus. The employee did not have symptoms and has not been diagnosed with the disease, according to an internal email seen by Business Insider.

This employee works out of Cisco's massive Silicon Valley headquarters, which spans San Jose and the neighboring town of Milpitas - specifically, in Building 24 on the campus. Cisco has about 39,000 full-time employees in the United States, many of them based in and around its headquarters.

Meanwhile, Cisco's videoconferencing unit, WebEx, is trying to help companies cope with their own workforces who may be working at home en masse. Its WebEx unit is offering free 30-day licenses to use the videochat and conferencing tool.

Here's the email sent on Friday from Fran Katsoudas, Chief People Officer:
