3 unlinked Covid-19 community cases among 9 new infections in Singapore

Singapore

THERE were nine new coronavirus cases confirmed as at noon on Friday, including three in the community, said the Ministry of Health.

All three community cases are currently unlinked.

No cases were reported in workers' dormitories.

There were also six imported cases that had been placed on stay-home notice on arrival in Singapore, said the ministry. Among them are five Singaporeans or permanent residents.

The new cases take Singapore's total tally to 62,245.

Singapore has had 34 deaths from Covid-19 complications, while 15 who tested positive have died of other causes.

A breath test that can accurately detect Covid-19 within two minutes has received provisional authorisation from Singapore's Health Sciences Authority (HSA), according to the authority's website.

This is the second such system to receive the HSA's provisional authorisation.

Developed by local medical technology firm Silver Factory Technology, the TracieX breathalyser has been shown to be almost as accurate as polymerase chain reaction (PCR) tests.

Silver Factory was founded in January last year as a spin-off from Nanyang Technological University.

These fast tests will facilitate safe travel arrangements and screenings at large-scale events.

Compared with PCR tests - the gold standard for testing - the disposable breathalyser's sensitivity rate was previously reported to be over 95 per cent, and its specificity, more than 99 per cent. Sensitivity refers to a test's ability to identify those infected as positive, while specificity refers to a test's ability to correctly identify those not infected as negative.

It is also cheaper, costing around US$20 (S$27) each.

Earlier in May, a breath test developed by Breathonix, a spin-off from the National University of Singapore, received the HSA's approval - the first in the country to do so.

Breathonix has since conducted a few thousand tests for its pilot deployment at Tuas Checkpoint. Each test was completed in 40 to 60 seconds. THE STRAITS TIMES
