Health authorities in Hong Kong are investigating whether the coronavirus is infecting people at bars and restaurants in the Central nightlife spot, Lan Kwai Fong, after a man who tested positive said he had been drinking there during his incubation period, RTHK reports.

Two other patients have also told the authorities they had visited a gym run by the Pure Group in the Lan Kwai Fong area of Central, while two other people who tested positive had also been there recently.

On Wednesday, the authorities said the only local case of the day was a woman who had gone for drinks and dinner in the popular entertainment area.

This comes as the city reported 16 new infections. Most of the patients had recently been out of Hong Kong, including places such as Canada, Spain and the UK. One of the patients is a pregnant woman.

In the past two weeks, Hong Kong has reported 88 infections, taking the total number of cases recorded in the city to 208.

Eighty-one patients, or 92 percent of the cases, were people who had been overseas during their incubation period.

Among them, only two are non-Hong Kong residents.
