Long queues formed outside Covid-19 testing centres in Macau on Monday as the SAR continues a mass testing exercise.

Authorities in the gaming hub have so far identified 34 coronavirus infections.

More than 300,000 people have been tested since the work began Sunday.

At some busy testing centres, residents queued for an hour before their specimens were collected.

Macau authorities say they aim to test everyone by noon on Tuesday, adding that those who didn't get tested after the deadline will be escorted by police to designated testing sites, and will be required to stay there until they get their result.

Macau has beefed up its anti-epidemic measures in view of the latest infections, suspending schools and advising businesses to close temporarily.

Passengers must also present their health code before boarding public transport.
