The UK super spreader who inadvertently passed the coronavirus to at least 11 people has been named as 53-year-old scout leader Steve Walsh. In a statement released on Tuesday morning Mr Walsh said he had "fully recovered" but remains in quarantine in a London hospital. In Britain, concern is rising as the number of coronavirus cases in the UK doubled within 24 hours. Speaking in the House of Commons health secretary Matt Hancock said the situation "would get worse before it gets better." Police have been granted special powers to force infected patients into quarantine. In Brighton, a second branch of the closed GP surgery shut down this morning amid a coronavirus scare. It comes as the World Health Organisation announced an official name for the virus - Covid-19 - and warned the outbreak poses a "very grave threat".
