Among the patients, aged 38 to 79, two arrived in Hong Kong from high-risk places while the other two were from medium-risk places.

Three of them tested positive during quarantine, including a patient who is a close contact of a previous imported case. The remaining one tested positive upon arrival at Hong Kong International Airport.

Meanwhile, specified people linked to Golden Glory Court, Phase 1, Golden Lion Garden in Sha Tin are reminded to undergo testing tomorrow in accordance with the compulsory testing notice. 

The Government will reopen a mobile specimen collection station at the open area outside Golden Glory Court tomorrow to facilitate people subject to compulsory testing.
