Scientists say they have identified a stealth version of Omicron that cannot be distinguished from other variants using PCR tests.

. The stealth Omicron lacks the genetic deletion on the spike protein at 69-70 which produces the S-gene target failure in some polymerase chain reactions. Even though the county has almost no confirmed cases involving omicron a sampling this week showed the variant represented almost 100 of the coronavirus strains in the wastewater facility samples Orange. Nearly 80 of Covid-positive samples sent for genome-sequencing by laboratories in the city have been found to contain the BA2 sub-lineage of the Omicron variant nicknamed the stealth.

There are reports it is starting to spread quickly in the UK Norway Sweden France and India. British health chiefs are now officially keeping tabs on a version of Omicron that is harder to track amid fears it may have spread to thousands. This has been used as a proxy for Omicron cases previously.

Its found in 49 countries and its rapidly replacing the delta variantLast week scientists identified a second sublineage. Health and Security Agency UKHSA announced Friday it is investigating a sub-lineage of the omicron coronavirus variant known. Everything we know about new under investigation Covid-19 strain BA2.

New stealth Omicron raises fears. Initial analysis shows no differences in hospitalisations for BA2 compared to BA1. The omicron variant has quickly surpassed the delta variant in collections taken from wastewater sampling sites in Orange County officials said.

The rise of the subvariant is alarming some scientists who say it may need its own Greek letter. According to researchers even as the BA2 sub-strain shares 32 strains with BA1 there may be. While the new stealth Omicron strain has many mutations in common with standard Omicron that first emerged in South Africa it lacks a particular genetic material that allows laboratory PCR tests to detect COVID-19 cases.

What is subvariant BA2 and should we be worried. It is expected that vaccines also. It is called so as it cannot be picked up in RT-PCR tests and only genome-sequencing can detect it.

Stealth omicron has gone from 20 to 45 of cases in Denmark and there are 30000 new cases a day in the country. Denmarks Statens Serum Institut said. In other words the original strain has a mutation in the form of the deletion of the S gene while the sub-strain does not have the same mutation.

The subvariant appears to be outpacing other substrains of Omicron in some regions of the world. BA1 the original sublineage is by far the most prevalent. All you need to know about the sub-variant Premium A health worker takes a swab sample of a passenger for the Covid-19 test PTI 2 min read.

Scientists have detected a new type of Omicron that may complicate surveillance effortsIts nicknamed Stealth OmicronResearchers have separated Omicron into two sublineages. Nearly 80 of COVID samples sent for genome-sequencing by labs in Kolkata have the BA2 sub-lineage of the Omicron variant nicknamed the stealth version as per TNN. Antibiotic resistance killed 12 million people in 2019 study says Nocebo effect cause of most COVID vaccine side effects.

Is stealth Omicron a cause of concern. Researchers say that it is too early to know whether the new stealth version of Omicron has the same transmissibility as the initial.
