(Updated at 9:15 p.m.) A second office in Crystal City is being sanitized after another coronavirus exposure.

“In the last hour, we were notified of a confirmed case of COVID-19 (Coronavirus) relating to a guest of a tenant occupying space at 2345 Crystal Drive,” said a memo sent by property owner JBG Smith earlier today and obtained by ARLnow. “The tenant is located on the 11th floor of 2345 Crystal Drive. It is our understanding that the guest of the tenant attended a meeting within the tenant’s space for approximately one hour on Thursday, March 5th, and the guest later tested positive for COVID-19 on Monday, March 9th.”

“The tenant has notified their staff and has advised any staff that was in contact with the infected individual to self-quarantine,” the memo continued. “The tenant has also engaged an environmental contractor to begin disinfecting their space.”

Amazon has one of its temporary HQ2 offices at the building, but ARLnow hears that the affected office is not Amazon’s.

On Monday ARLnow first reported that another person who had tested positive for coronavirus had visited a pair of offices on the northern end of Crystal City.
