PCR tests can detect COVID-19 Omicron variant – WHO

SWITZERLAND, US: While PCR tests can detect infection with Omicron, studies are looking to whether the Covid-19 variant of concern has any impact on other test types, the WHO said Sunday.

“The widely-used PCR tests continue to detect infection, including infection with Omicron, as we have seen with other variants,” the World Health Organization said in an update on what is known so far about the new variant.

“Studies are ongoing to determine whether there is any impact on other types of tests, including rapid antigen detection tests.”

The WHO on Friday declared Omicron, first detected earlier this month in southern Africa, to be a variant of concern.

The classification put Omicron into the most troubling category of COVID-19 variants, along with the globally dominant Delta, and its weaker rivals Alpha, Beta and Gamma.

Omicron spread across the globe on Sunday, shutting borders and renewing curbs as the EU chief said governments faced a “race against time” to understand the strain.

The variant has cast doubt on global efforts to battle the pandemic due to fears that it is highly infectious, forcing countries to reimpose measures many had hoped were a thing of the past.

In its update, the WHO said it was “not yet clear” whether Omicron spreads more easily from person to person, or whether infection with the variant causes more severe disease compared to other strains.

“There is currently no information to suggest that symptoms associated with Omicron are different from those from other variants,” the UN health agency said.

While preliminary evidence suggests there may be an increased risk of people who previously had Covid being reinfected with Omicron, information is currently limited.

The WHO said it was working to understand the potential impact of the variant on existing counter-measures, including vaccines.

The WHO has said studies into various aspects of the new variant would take several weeks to reach conclusions.

“WHO is coordinating with a large number of researchers around the world to better understand Omicron,” it said.

Meanwhile, American pharmaceutical firm Moderna, one of the biggest makers of vaccines against COVID-19, said on Sunday that it could reformulate the vaccine against the Omicron variant of COVID-19 in early 2022.

“We should know about the ability of the current vaccine to provide protection in the next couple of weeks,” Paul Burton, the chief medical officer of Moderna said during an appearance on a BBC show.

“If we have to make a brand new vaccine, I think that’s going to be early 2022 before that’s really going to be available in large quantities,” Burton added.

Meanwhile, as the Omicron COVID variant forces nations to close down borders, experts feel that the current vaccines may not be able to protect from this variant first found in southern African nations of South Africa and Botswana.

European Commission chief Ursula von der Leyen said vaccine manufacturers needed a few weeks to understand the quality of mutations. “We know we are now in a race against time,” von der Leyen said. – HINDUSTAN TIMES, INDIAN EXPRESS
