The UK’s medical experts stress upon an ensuing endemic of Covid-19 and hence, the need to re-introduce face masks. “Without ramping up surveillance, and in the face of waning immunity, we are travelling into winter more vulnerable and with blinkers on,” warned Christina Pagel, a member of the Independent Scientific Advisory Group for Emergencies. They advise to adopt any and every precautionary measure, keeping in view the lack of infrastructure to deal with a surge in cases, Covid or not. Prof Pagel has further predicted the new wave to potentially cause extreme pressure on the health service, and repeat last winter’s “unprecedented” NHS crisis of Covid, flu and respiratory virus, that came all around the same time.
