The company said it would increase disinfection at the station and has asked other employees who may have come in close contact with the manager to stay home.
After the virus began spreading within Hong Kong during the Lunar New Year holiday last month, several businesses asked employees to work from home for about 14 days, the incubation period of the disease, in an effort to contain the outbreak during a peak travel season.
But as more people have returned to the office in recent weeks, subways and buses have filled with commuters wearing masks and some wearing protective goggles and gloves.
A police officer in the city tested positive for the virus on Thursday, raising alarm that residents could have become infected as he patrolled the streets. Fifty-nine other officers, including those who had attended a gathering with him, have been placed under quarantine.
Hong Kong’s civil servants have been asked to work from home for another week, and schools remain closed until March.
The city has 74 confirmed cases of the coronavirus. Among them, two have died and 12 have recovered.
