Experts felt that since the complete nature of the variant was not understood, it would be crucial to step up vigilance and follow Covid-appropriate behaviour.
However, Director of Public Health Dr G Srinivasa Rao assures that there is no cause for concern.
He said many cases of Delta Plus AY.4.2, a new mutated form of coronavirus that has killed thousands of people in several countries like Russia and the UK, have been found in India.
So far, this variant has not been detected in India in over 68,000 samples from SARS CoV 2 infected patients that have undergone whole genome sequencing under the INSACOG project.
In the last week, AY.4.2, dubbed as 'Delta Plus', accounted for approximately 6 per cent of all Delta cases -- confirmed through genome sequencing across England.
The variant has two mutations in the spike protein, which helps the coronavirus invade the body’s cells.
Samples of relatives of patients who came positive and those who came in contact were also taken, but the reports of all were negative.
According to the health department, six cases each were detected in Gadchiroli and Amravati, five in Nagpur, four in Ahmednagar, three in Yavatmal, two in Nashik and one in Bhandara district.
COVID-19: Maharashtra allows under-18 people to visit malls with age proof; state reports ten more Delta Plus variant cases

Out of the newly detected cases, seven were in Mumbai, three in Pune, two each in Nanded, Gondia, Raigad, Palghar, and one each in Chandrapur and Akola districts, the statement said.
VK Paul, who also heads the national Covid task force, said given this variant’s geographical spread so far, it is evident that it may not be able to go beyond Delta Plus’s extent of transmission.
The exact number of samples sent for genome sequencing and the period during which they were analyzed is not mentioned.
The Commissioner of Police instructed business establishments not to sell goods to those who don’t have masks.
The Variant of Interest (VOI) was found in genome sequencing by INSACOG, a genomic consortium comprising a group of 28 labs.
