A male Senior Immigration Assistant stationed at the Control Support Section has tested positive for COVID-19, the Immigration Department announced today.

The staff member is mainly responsible for providing support services at the 14th and 16th floors of the Wan Chai Immigration Tower. Both floors are not open to the public.

The department said the staff member, who has no recent travel history, wore a mask when performing duties and that his body temperature was normal, adding that he followed disease prevention measures at work.

He last performed duties on July 10 and sought medical treatment at a clinic. He was notified of the test result this evening.

The Centre for Health Protection is investigating the cause of his infection and whether he had been in close contact with other people.

The department has also arranged thorough cleansing and sterilisation for the staff member's workplace.

It will continue to maintain close liaison with the centre and proactively co-operate with its quarantine work, which includes arranging related immigration staff members to undergo COVID-19 testing.

The department emphasised that it has been strictly implementing disease prevention measures, including measuring the body temperature of people before they enter the building, providing employees with masks and other protective equipment, requiring employees to wear masks when performing duties, and stepping up cleaning and sterilising measures.

It has reminded its staff to pay attention to personal hygiene and stay vigilant.
