The Centre for Health Protection today said it is investigating two additional imported COVID-19 cases, both involving the L452R mutant strain.

One of the patients, a 31-year-old woman, arrived in Hong Kong from the Maldives via Doha. She is a close contact of a previous imported case and tested positive at a public hospital where she accompanied that patient.

The other case is a 43-year-old female foreign domestic helper who arrived from the Philippines and tested positive during quarantine.

In view of a non-locally confirmed case involving a patient who had stayed in Hong Kong, one specified premises is included in the compulsory testing notice.

Three schools are also covered in the notice due to outbreaks of upper respiratory tract infection or influenza-like illness.

The service period of several mobile specimen collection stations will be extended to facilitate people subject to compulsory testing.

A total of 60 cases were reported in Hong Kong in the past 14 days. One is a local case with an unknown infection source and the rest are imported.
