More than 300 workers at the Chevron oil company in London’s Canary Wharf business district were sent home over fears that an employee may have contracted the coronavirus, according to a new report.

The unidentified employee reported flu-like symptoms after returning from a country where the deadly bug is prevalent, Metro UK reported.

The American-based, multinational oil giant advised staff to work from home until the employee’s test results come back.

“Chevron continues to monitor the situation very closely, utilizing the guidance of international and local health authorities,” a company spokesperson told the outlet in a statement. “Our primary concern is the health and safety of our employees and we are taking precautionary measures to reduce their risk of exposure.”

Affected employees include traders, downstream analysts and office staff, according to the Financial Times

Chevron’s office is located in the dense Westferry Circus business district of Canary Wharf, home to various banks including Citi, HSBC and Barclays. About 120,000 workers pass through the district daily.

The UK’s Department of Health and Social Care reported Tuesday that nearly 6,800 people have been screened for coronavirus in the country, though so far only 13 have tested positive.

In a worst-case scenario, 80 percent of Brits could be infected, of whom 2 percent — or 500,000 people — could die, according to official reports obtained by the Sun.

A government advisory notice warned anyone returning to the UK from China’s Hubei province, Iran, parts of South Korea or specific locked-down areas in Italy to self-isolate — regardless of whether symptoms develop.
