A contagious new variant of coronavirus has been detected in the United Kingdom. This strain of the virus is thought to spread more easily and more quickly and is also harder to detect. In light of this, on Saturday afternoon, the UK government announced tougher restrictions for London, the South East of England and the East of England. The measures being introduced in the regions in question include the closure of non-essential shops, gyms and entertainment venues, travel restrictions and the urgent advice not to receive any visitors at home.
