Thirty three samples of 122 tested fortnightly for Covid-19 genome sequencing have shown that 26 of them were the Delta variant in Goa. The samples were taken when the second wave of the pandemic was at its peak in May, said state epidemiologist Dr Utkarsh Betodkar.
While reports for 89 samples are awaited from Pune, of the 33 received by the Goa government, six were the Kappa variant and one of Alpha. While the new Delta plus variant, that has been found in Maharashtra has manifested in the border district of Sindhudurg, no case of the Delta plus variant has been found in Goa so far, Betodkar said.
The genome sequencing, Betodkar said, shows that the second wave was definitely due to the Delta variant. “Seventy nine percent of the 33 samples we have received show that the Delta variant was responsible. Now maximum population of Goa has immunity towards this particular strain. have to continue with our genome sequencing and watch out for a new strain.
Now we know which strain was responsible for our second wave. If at all the third wave comes and the same mutant continues, then possibly we will have a small wave and then it’ll go. Our concern is now to look out for a new variant. It is already seen in Maharashtra, the Delta plus. More details are yet to come, we don’t know much about this particular strain. But if something like that comes then our thought will change completely about it,” said Betodkar.
“As of now there is no Delta plus in Goa but our surveillance will continue,” said Betodkar.
The number of active cases in Goa on Tuesday was 2920 and the test positivity rate was now at 7.02 percent. At the peak of the second wave, the number of active cases had come close to 33,000 in mid-May and the test positivity rate was then over 50 percent, one of the highest among Indian states.
