The ministry said the mutated UK strain was detected in eight samples at the National Centre for Disease Control, one at the National Institute of Biomedical Genomics, Kalyani (near Kolkata), one at the National Institute of Virology Pune, seven at the National Institute of Mental Health and Neuro-Sciences Hospital Bengaluru, two at the Centre for Cellular and Molecular Biology in Hyderabad and one at the Institute of Genomics and Integrative Biology, Delhi.
The Centre on Saturday strongly advised 12 states and Union Territories reporting a surge in coronavirus cases to significantly increase testing and ensure people follow COVID-appropriate behaviour, noting that one infected person could spread infection to an average of 406 individuals in a 30-day window without restrictions.
