Macao could be facing a second, or even third, round, of mass nucleic acid tests (NAT).
Health Bureau (SSM) Director Alvis Lo Iek Long said the decision to run further testing would depend on the results of the current round and whether those who had been in close contact with the latest four Covid-19 patients are later diagnosed with Covid-19.
Testing is mandatory for all those who wish to leave Macao, enter certain premises or take public transport, as those who fail to take the test and come up with a negative result within the three-day period will have their Macao Health Code colour turn yellow, The Macau Post Daily reported.
Those who test negative will have their Macao Health Code stay green. Those who test positive will have their Macao Health Code turn red and will be taken into isolation treatment.
According to Lo, those who have a yellow Macao Health Code due to their failure to undergo the free mass test within the three-day period will then have to undergo a paid test for their code colour to return to green if the test turns out to be negative.
