An employee from Citigroup's Manhattan office tested positive for the coronavirus, the Wall Street firm said Friday.

The employee was diagnosed in Singapore on Friday while on personal travel. The Citi worker was last in the Manhattan office on Friday, March 6. The employee is not part of the bank's trading operations, according to people familiar with the matter.

The company said the employee only started to feel ill on Thursday, March 12, and went to a local hospital in Singapore where they were diagnosed.

The firm told company employees that they are at "low risk and there is no need for anyone to self-quarantine."

"We are cooperating fully with all appropriate government and health authorities and we are adhering to their guidelines on actions to be taken. Citi has advised colleagues who worked near this person prior to his travel to self-monitor their health and has given all colleagues who work on that floor the option to work from home," Citi said in a release.

The employee is based at 388 Greenwich St. in New York on the 24th floor.

Citi, along with other Wall Street banks, has been making contingency plans due to the fast-spreading coronavirus. This week the bank sent some traders and salespeople from its headquarters in downtown Manhattan to a backup facility in Rutherford, New Jersey.

Cases of the deadly virus have spiked in New York. The state of New York now has more cases than any other state in the U.S. as the number of newly confirmed infections surged by 30% overnight to 421, New York Gov. Andrew Cuomo said Friday.

Morgan Stanley said Tuesday that an employee at its suburban New York office tested positive for the coronavirus disease.
