Advertisement Britain must go into an 'Asia-style' lockdown now with nurseries and places of worship closed, hotels commandeered as isolation centres and masks worn in every public space, experts have warned. Former WHO director Anthony Costello said only 'a total clampdown' would succeed in stopping the mutant strain of coronavirus ripping through the country. Professor of operational research at UCL Christina Pagel added that she thinks the current lockdown restrictions are likely to fail and measures seen in China and Vietnam should be brought in. In Wuhan, where the virus originated, authorities would go door-to-door to monitor people and made sure people with Covid self-isolated.
