Pandemic in Asia
It is disquieting news that there is a renewed surge in COVID-19 infections in parts of the world (Page 1, “South Korea registers over 6 lakh COVID cases in a day”, March 18). We must be alive to the fact that a virus has the ability to mutate into new forms and pose new challenges. It is premature at this stage to conclude that the pandemic is all over. We must step up disease surveillance, genome sequencing and the booster dose programme.
