The Centre for Health Protection today said it is investigating six additional COVID-19 cases, of which one is locally transmitted and five are imported.

At a press briefing this afternoon, the centre's Communicable Disease Branch Head Dr Chuang Shuk-kwan said the local case involves a 22-year-old man who works as a construction worker at a site in Kai Tak.

She added that nine workers who had close contact with him have to be quarantined.

“Because for construction site workers there are many job types and under the same job type they are managed by one company, so around 10 workers have a close working relationship with each other.

“They may have meals together in a common room and take a rest there, so we consider them as close contacts.

“And two of the close contacts had some symptoms when we found them last night and sent them to hospital.”

Dr Chuang also said there are about 500 workers from different companies working at the site.

“Because they work in the same workplace, we have distributed deep throat saliva (specimen) bottles to them in case there are chains of transmission.”

The centre also distributed specimen bottles to residents of the building where the patient lives.

The imported cases are from the Philippines, Tunisia, India and the UK.
