Singapore picks up seven of 18 unlinked cases through rapid testing
Singapore has started carrying out rapid testing for Covid-19 and picked up seven of yesterday's 18 unlinked cases through this method, said Health Minister Ong Ye Kung.
The new testing strategy, along with higher virus transmission in the community, explains why more cases were reported yesterday, he added.
The country saw a total of 49 new cases yesterday, 38 of which were locally transmitted. Of these, 20 were linked to previous cases, while 18 were unlinked cases.
Addressing reporters at a virtual press conference, Mr Ong said antigen rapid test kits have been distributed to 236 of the 900 Public Health Preparedness Clinics (PHPCs). To speed up detection of the virus, everyone who sees a doctor with signs of an acute respiratory infection will have to undergo one of these tests, in addition to the slower but more accurate polymerase chain reaction (PCR) test.
More of the rapid test kits will be distributed to the other PHPCs in the coming days, Mr Ong said.
He added that the numbers in his ministry's daily case reports will be based on PCR test results.
Antigen rapid testing produces results in 20 minutes and can be done on-site.
In contrast, PCR tests swabs have to be transferred to a laboratory, which adds to the wait of up to 48 hours for results.
The quicker turnaround time for the rapid tests means that the Health Ministry is able to start contact tracing and ring-fencing at an earlier stage. - THE STRAITS TIMES
