Two SARS-CoV-2 variants detected in Maharashtra, Kerala
NEW DELHI, Feb 23: Two variants of SARS-CoV-2 – N440K and E484K – have been detected in Maharashtra and Kerala, but there is no reason to believe presently that they are responsible for the surge in cases in some districts in these two states, the Centre said on Tuesday. One of the two variants has also been detected in Telangana.
Addressing a press conference here, NITI Aayog Member (Health) VK Paul said that 187 people have tested positive for the UK strain of SARS-CoV-2 in the country so far, while six people have been detected with the South Africa variant. Also, one person has tested positive for the Brazil variant strain.
“Both the N440K and E484K variants of SARS-CoV-2 have been detected in Maharashtra. In Kerala and Telangana also these variants have been found. Also, three other mutated strains – one each from UK, South Africa and Brazil are already present in the country,” he said.
“But there is no reason for us to believe, on the basis of scientific information, that they are responsible for the upsurge of the outbreak in some districts of Maharashtra and Kerala,” Paul added.
Reporting only detection does not lead to any attribution for a phenomenon on the ground, because to relate the occurrence of a virus mutation to change in disease pattern, other epidemiological information and clinical information have to be linked to these mutants, Paul said, adding, “because otherwise these (mutations) happen but they have no influence on the pandemic.”
He said the behaviour of mutations is being constantly and closely watched in the country and 3,500 strains have been sequenced so far.
“When we are doing sequencing, we are looking for any abnormal shift in the virus character. We have been watching the mutants,” he said.
“Today, based on the information and as analysed and understood by a very eminent scientific advisory group of Indian SARS-CoV-2 Genomics Consortium (INSACOG), we would like to underline the fact that we do not see attribution of mutant strains to the upsurge of the infection being seen in some districts. But this is work in progress. We will continue to watch the situation with full responsibility,” Paul said.
The SARS-CoV-2 Genomics Consortium (INSACOG) was established in December-end for laboratory and epidemiological surveillance of circulating strains of SARS-CoV-2 in the country. – PTI
