The Delhi High Court Wednesday sought the Centre and the city government's stand on a plea by a mother wanting to know the outcome of the genome sequencing test of her Covid positive son as he was not being discharged by a private hospital for the lack of clarity on the virus variant. The 18-year-old arrived at the Delhi international airport from one of the ‘at-risk ‘countries and tested positive for COVID-19. He has been in isolation at a private hospital since the morning of December 25.
