Delta variant found in 725 samples k’taka

Bengaluru: sequencing positive sample genome Covid-19 on Friday revealed the existence of the Delta variant (B.1.617.2) in 208 cases.
On Thursday, 200 samples were infected with this variant.
Overall, the Delta variant was found in 725 samples processed, and the majority, 525, originated from Bengaluru, followed by 77 of Vijayapura and 40 from Udupi.
Two laboratories in Bengaluru – Nimhans and the National Center for biological scineces – are involved in the order of the sample genome.
Nearly 3,000 samples have been processed in two labs and Nimhans have done more than 1,000 of them.
The Delta variant is the most dominant Sarscov2 variant circulating in May and June in Karnataka.
However, the health department’s sources said the sample was almost a month and the results came now.
When this data is given to the district, the Positive Covid people will recover or even repatriated from the hospital.
“When we get a genome sequencing data, we are crosscheck to ensure that contacting contacts is done effectively.
In most cases, the patient will recover,” said the BBMP Chief Health Officer Dr.
BK Vijendra.
While some experts say the genome sequencing data does not help overcome supervision, Dr V Ravi, Virologer, State Nodal Officer and Chairperson, the Covid-19 Committee throughout the Genome Sequencing (WGS), said there was absolutely no delay and 15 days was the minimum time needed for Sample genome sequencing.
Delta variant detected in the last two days is a sample received through routine supervision in the first half of June.
The backlog was removed after two weeks using Miseq Illumina which was a sample 384 sample.
Only swab samples with cycle threshold value (CT value) below 25 are qualified for genome sequencing.
The CT value shows the number of cycles in the RT-PCR test needed to strengthen the RNA virus to achieve a detected level.
“Sequencing genomes need around 10-15 days.
Collecting samples today and producing results the following day is not done anywhere in the world and it’s really rubbish to expect it.
We waited 384 samples to start processing it,” said Dr.
Ravi said.
He added that the genome sequencing is a tool to detect the emergence of a new variant and cannot guide public health policies.
“Wearing a mask, keeping social distance and getting a vaccine will be the only way forward to load spread.
For that, the genome sequencing is not needed,” he said.
Sequencing genomes are carried out in two batches every month.
Samples are collected in the results of the results of the first 15 days with the end of the month.
Samples were collected in the results of the second half of the results in the middle of next month.
“It takes 3-4 days for the sample arriving, sequencing takes 10 days and a day data analysis,” said Dr.
Ravi.
