A Google employee in its Bangalore, India, office has tested positive for the COVID-19 coronavirus and is in quarantine, according to internal documents viewed by CNBC.

"We are sorry to report that we have one confirmed case of a Bangalore-Based Googler testing positive for COVID-19," said Anand Rangarajan, director of engineering and Bangalore site lead for Google in an email to Bangalore employees Thursday.

"The Googler contracted the virus after traveling overseas, and was in the RMZ office on Monday, 9th March having not displayed any symptoms and passed the temperature screening," Rangarajan wrote. "A few hours later, the Googler felt unwell and decided to return home. They were subsequently screened at a government-authorized hospital, placed in government quarantine and today confirmed as being infected by COVID-19. We've been in in touch with the Googler and are offering our support."

The company did not respond to requests for comment.

It's the second known case of a Google employee contracting the disease and potentially being in contact with other workers. At the end of February, A Google employee from its Zurich office tested positive for the coronavirus, triggering the company's initial travel restrictions. As the outbreak has spread, Google this week told nearly all of its global employees to work from home for the coming weeks, including its more than 100,000 North American employees who were asked to work from home until at least April 10.
