Pubs are only dangerous for people already at risk of Covid and airplanes are 'safe' because they have air conditioning almost as good as operating theatres, an expert has said. Professor Robert Dingwall, one of Britain's leading sociologists, told a webinar today there was only a 'small' risk of catching the virus in a pub and then being hospitalised. But he said this was 'heavily age-loaded' and focused on 'specific groups where one can think about specific advice on protection'. And, sparking hopes of holidays this summer, Professor Dingwall added planes are 'fundamentally safe environments' because of their excellent ventilation systems.
