Those suspected of having Omicron Covid-19 variant to be sent to NCID, no home recovery allowed

SINGAPORE – People suspected of having the new Omicron coronavirus variant will be isolated at the National Centre for Infectious Diseases until doctors are confident they are no longer infectious through repeat testing.

They will not be allowed to recover at home, said Health Minister Ong Ye Kung on Tuesday (Nov 30).

Full contact tracing will also be carried out for confirmed cases, with patients’ close contacts to be quarantined for 10 days at dedicated facilities instead of being able to isolate themselves at home.

Polymerase chain reaction (PCR) tests will be conducted at the start and end of the quarantine period for such individuals, with swab samples prioritised for genetic sequencing to ascertain if they have the Omicron variant.

“The healthcare protocols will be a lot stricter and quite similar to the initial protocols we implemented when we first encountered Covid-19,” Mr Ong said at a press conference.

The new variant, first detected in South Africa, has been classified as a variant of concern by the World Health Organisation. A variant of concern is one that shows evidence of higher transmissibility and virulence, leading to more severe disease that requires hospitalisation and causing deaths. Four other variants fall into this category, including the currently dominant Delta variant.

Mr Ong also observed that a particular PCR test, produced by biotechnology firm ThermoFisher, can indicate if a person is likely to have been infected by the Omicron variant.

This test will be prioritised for use on travellers, he said, adding that it is not foolproof but will allow Singapore to act faster and implement differentiated healthcare protocols.

In a way, people can think about it as having two separate viruses in Singapore, Mr Ong said.

“We’ll have two separate variants, two separate sets of healthcare protocols. One set for Delta, one set for Omicron, and the way to differentiate it is the ThermoFisher PCR tests,” he said.

The minister also stressed that the country must push ahead with vaccination.

“This is absolutely the wrong time to argue that because there are new variants, let’s not vaccinate and wait for a new vaccine,” he said. “People die because of such arguments and such decisions.”

He added that there is a good chance existing vaccines will still work against the new variant, saying: “It is not the case where there are mutations and hence existing vaccines will not work because the human body is much more capable than that.”

Tougher healthcare protocols for suspected Omicron cases

Mr Ong compared the current situation to a game of snakes and ladders, where the outcome of the next throw of the die remains unknown.

If the Omicron variant is more infectious or harmful, with vaccines not working well against it, Singapore will have landed on a “snake”, he said. “We will go down, and it will set us back a long way.”

But if the new variant is more infectious but milder, it may become dominant over the Delta variant – a positive sign. This will enable Singapore to move towards living with Covid-19, Mr Ong said.

In the meantime, the country should take the prudent approach – implementing appropriate measures to prevent the new variant from establishing itself in the community, he added.

Finance Minister Lawrence Wong also said that Singapore’s fundamental strategy in dealing with the pandemic – no matter what new variant emerges – is to stay nimble and adjust measures quickly based on scientific evidence, ensuring its various lines of defence hold.

“This will not be the last variant of concern. There will be new mutations and we just have to be prepared. It may well turn out that Omicron will be not so threatening, a bit of a non-event – maybe, we hope. It may turn out to be worse,” he said. “But there may also be a possibility that another mutation down the road, next year, turns out to be far more threatening.

“At the end of the day, it goes back to what we’ve always emphasised – individual social responsibility and all of us doing our part, cooperating with the measures and staying united in fighting this pandemic.”
