The Centre for Health Protection on Friday reported 11 new coronavirus cases, eight of them local.

Half of the local cases have no clear source.

One of them is a university student who lives in Sau Mau Ping. He has not attended any face-to-face classes recently.

A 47-year-old clerk of the Labour Department who works at Cheung Sha Wan Government Offices has also caught the virus. He last went to work on Thursday.

The government says service counters on the floor where the man worked would be closed until further notice.

A 48-year-old clerk who worked at an office building in Central has also come down with the disease. His colleagues have been put under quarantine.

A 37-year-old woman who works part-time as a foreign domestic helper is the other unlinked case.
