Sir Lucian Grainge has been hospitalized after testing positive for coronavirus, multiple sources have confirmed to Billboard following the initial report by Variety.

The Universal Music Group chief executive officer and chairman -- who was ranked No. 1 on the 2019 Billboard Power 100 chart and was selected as the Billboard executive of the decade -- is currently undergoing treatment at Ronald Reagan UCLA Medical Center in Los Angeles. (A UMG spokesperson declined to comment.)

Billboard has obtained a memo sent to staff on Friday (March 13) from Gautam Srivastava, the evp of UMG human resources, that details the company's plans to deep clean and disinfect their Santa Monica office, along with confirmation that they have contacted each employee who "may have been in close contact in the last 14 days with the UMG employee who has a confirmed case of COVID-19."

"We understand that everyone is concerned for their own health as well as that of their co-workers, family, friends and our sick colleague," the memo reads. "Our best understanding is that even if you were in the same indoor environment, but not in close contact with the affected employee, your risk level is low under the CDC framework. For further advice as to what steps are recommended by the CDC, please refer to: https://www.cdc.gov/coronavirus/2019-ncov/php/risk-assessment.html.

In the meantime, please know that we are taking this matter very seriously. We are arranging for a deep cleaning and disinfection as soon as possible, and we have reached out to the Los Angeles County Department of Public Health for further guidance."

This is a developing story. Billboard will update this post when more information becomes available.
