Starting Tuesday, Deutsche Bank will divide sales and trading teams at its affected offices in a building across from its main towers in Frankfurt.

It’s sending some personnel to a recovery site until March 27 as a precaution, and some employees may be asked to work from home.

“Our colleague is in good health and good spirits but will remain under observation,” the bank said in an internal memo.

“All employees who have had contact with the affected colleague were informed directly, and we will undertake deep cleaning on floors N1 and N2 and other areas in DBC.”

KKR said it’s temporarily closing both of its London offices to have them sanitised and that staff there should work from home until further notice.

It’s requiring personnel who had close contact with the employee who contracted the virus to quarantine themselves for 14 days.

“This individual is at home and recovering well,” said Kristi Huller, a KKR representative.

“We continue to monitor the situation and will adjust our response as necessary.”

At financial hubs around the world, major firms have begun splitting up key parts of their workforces to limit the potential for an outbreak to spread through a division, disrupting business or even markets.

Banks as far apart as London-based HSBC Holdings Plc and San Francisco-based Wells Fargo & Co have confronted individual cases of the virus in recent days. At the same time, regulators are pressing lenders to accommodate the needs of clients affected by the illness.

“We expect no impact on our ability to operate our full range of services for our clients and recognise that this setup will require extra effort and discipline from all,” Deutsche Bank wrote in its memo.

The Frankfurt-based lender said employees working remotely won’t be allowed at offices where they aren’t assigned and that staff should avoid meeting socially with any colleagues stationed elsewhere.

The bank is also planning to take other “precautionary hygiene measures” to make the workplace safe.

KKR’s Huller echoed that.

“We are taking all necessary precautions, based on the advice from Public Health England, to ensure the safety and wellbeing of our employees,” she said.
