Express News Service NEW DELHI: India may still not be doing enough genome sequencing of SARS-CoV2 samples necessary to stay ahead of the virus and predict third Covid wave in time, feel experts. So far, genome sequencing of only about 15,000 samples across India has been carried out while experts say that considering India’s population, this number should have been at least 1 lakh if not more. It also grossly falls short of the target set up by the Centre in December-January to test 5 % of all positive samples in every state as part of its INSACOG initiative, which is a consortium of several institutions under the National Centre for Disease Control to carry out an extensive genomic surveillance of Covid virus in India.
