Oil giant Chevron has asked 300 staff at a London office to work from home as a precaution against coronavirus.
Chevron took the step after one of its staff returned with flu-like symptoms from a country where there have been cases of the disease.
The staff at the Westferry Circus office at Canary Wharf will continue to work from home “for the time being”, pending tests on the employee.
Coronavirus has caused a number of deaths around the world.
The staff at the Canary Wharf office mainly engage in downstream oil and gas products trading.
The company said: “Chevron continues to monitor the situation very closely, utilising the guidance of international and local health authorities.
“Our primary concern is the health and safety of our employees and we are taking precautionary measures to reduce their risk of exposure.
“Consequently, we have requested that our colleagues, based at our Westferry Circus office in London, work from home for the time being. It is our policy to not provide details of our employees.”
