AIIMS Chief Dr Randeep Guleria said that India needs to learn from the UK where the Delta variant is causing a surge in Covid-19 cases.
He said the Delta Plus variant, a mutated version of the more aggressive strain that drove the second wave in India, is undergoing additional mutation which could become a "variant of concern"
Dr Guleria said India could see a faster surge if aggressive Covid-appropriate behaviour is not followed. He also insisted on surveillance to guard against any spike in the Covid cases following unlocking in parts of the country.
He also stressed on the need to ramp up genome sequencing to see if there are more of Delta or Delta plus cases and how the virus is behaving in terms of these two variants.
