Neri study 93 samples, found omicron ba.2 at 77%

Nagpur: Sub-genealogy of BA.2 from the Omicron variant of Covid-19, also called ‘Stealth Omircon’, is to replace the B1.1.529 strain in a short time span among patients without symptoms and symptomatic patients throughout the city, as per study of neeri latest.
In the FIFTH Genome Sequencing (WGS) series by Neri Lab, BA.2 Share in the sample studied has increased by 10%.
Until mid-January, the omicron variant B1.1.529 remained dominant replacing Delta.
Recently, the authorities must tweak the testing strategy as BA.2 skip the RPCR target (SGTF) attack.
The fourth WGS series study conducted by Neer has revealed that BA.2 is the dominant variant in circulation between symptom cases.
Now, the Lab Surveillance has turned to the RP-Cr kit to check the samples suspected of omicron and the sub-linax.
The latest neeri studies have found BA.2 around 77% of the 93 positive patient samples of symptomatic and asymptomatic from the city.
Of the 77% positive samples, BA.2 consists of 30.5% of symptomatic cases and 69.5% cases asymptomatic.
Omicron B1.1.529 variant was found in more than 90% of the sample in the first two weeks of this month, but now the part is reduced to around 30%.
Samples that show omicron variants have 23.8% symptoms and 76.2% of asymptomatic cases.
This study consisted of mouthwash samples from patients without symptomatic and symptomatic from various sample collection centers and cellular collection vans used by NMC.
93 samples were collected between January 22 and January 26.
Dr.
Krishna Khairnar, Head of the Environmental Virology cell, Neer, said it seems BA.2 will be a variant that will be dominated in the coming days.
“We need to learn from the second wave.
Even though the situation looks controlled, we must remain vigilant.
We are alert and unable to reduce our guards at any time.
There is no need for a lot of time for viruses to mutate and gain strength, explode and claim life.
We need to firmly Continue WG in more places, “he said.
Neei’s study came a day after Maharashtra reported more than 100 Covid deaths in a day for the first time after September last year.
While big cities witnessed a decline in the number of cases, a surge continued in Nagpur.
There are around 10 deaths in the district even though the omicron variants are marked as causing mild infections.
The hospital has also observed that patients with symptoms have increased, regardless of vaccination status.
The fifth sequencing series by Neer 22 to 26 samples | 93 Results * Omircon Lineage BA.2 found in 77.4% samples.
And omicron variant B.1.1.529 in 22.6% * BA2 case – 30.5% symptoms and 69.5% asymptomatic * B1.1.529 Case – 23.8% symptoms and 76.2% asymptomatic
