Hong Kong recorded a single imported Covid-19 case on Saturday – extending a run without any locally acquired coronavirus infections into a fourth day.

Health authorities said the imported case involves a 42-year-old woman who had arrived from Indonesia. She is asymptomatic.

The city hadn’t reported any cases, imported or otherwise, over the previous two days, with the last local cases confirmed on Tuesday.

Over the past two weeks, the city has recorded 19 cases, including five local cases with an unclear source of infection and one possibly local case.

Hong Kong has confirmed 11,837 Covid cases since the start of the pandemic, and 210 related deaths.

Health officials are also reminding people who live at 37-39 Fuk Wing Street in Sham Shui Po or Tower 6 of Island Harbourview in Tao Kok Tsui to undergo compulsory testing on Sunday.

The buildings are covered by a testing order for buildings where a local Covid-19 case with the N501Y mutant strain has been discovered.
