Nagpur: In a convincing development for the city, sequencing genomes have revealed the existence of delta and delta sub-genres as the dominant variant in Nagpur so far.
Studies by CSIR-NEEI environmental virological cells have ruled out the Omicron variant (B1.1.529) in one of 68 samples.
Delta variant (B1.617.2), declare a concerned variant, was found to be behind acceleration in the case during the second wave starting from Nagpur and Amravati in March this year.
Although the variant causes severe Covid disease, now the patient remains light.
Kana is the only positive patient documented officially now released.
According to Pune-based NIV reports, patients were found like Omicron but officials had calculated it as a positive omicron.
68 samples belonging to Covid patients, including one international leaflet, which was tested positively between November-end and December 18.
All 68 samples belong to vaccinated patients.
35 other samples from the same period are in the process, said Dr.
Krishna Khairnar, cell head.
In accordance with civilian officials, between 35 samples, 17 people were vaccinated and 18 were not vaccinated.
Environmental Virological cells have now carried out sequencing genomes 852 samples since October 2020.
“Of the 68 samples, 11 was taken from contact near international passengers.
Everything is a positive delta.
Samples are processed in a week by CSIR-Neer working with CCMB Hyderabad.
This study shows that Delta is still the dominant variant in Nagpur, “said Dr.
Khairnar.
Scientists warn that the threat of omicron seriously.
“If Covid-APT behavior is not followed, then it is a matter of time that Omicron can replace Delta as a dominant strain,” he said.
On whether the sample size 68 was enough to put aside the other variants, Dr.
Khairnar said, “We are in the best position to say this.
At a time, only 5% of the total samples are learned.
Now, because we are low forward, we sort the sample of all Daily Covid patients.
Nagpur is the only city sorting all positive samples, “he said.
He stressed that amid the threat of various variants, the best defense against the virus was SMS (cleaning, mask and physical distance).
“It will remain effective during the pandemic,” he said.
Cells have sorted all positive covid daily samples from Nagpur since June.
However, cells have been involved in SARS-COV-2 sequencing from the nagpur sample since October 2020.
