Coronavirus: Researchers warn droplets can spread up to 20ft

Daily Mail - Science & tech 

The social distancing rule of two metres (6.5ft) may have to be trebled when winter strikes, scientists have warned. Chinese scientists found certain weather conditions allow the disease to spread further in the air. Their preliminary findings suggest droplets carrying the SARS-CoV-2 coronavirus can travel up to 20feet (six metres) in cold and humid areas. However, a 1.4m range for social distancing -- less than current guidelines -- is sufficient to block at least 95 per cent of the virus irrespective of conditions. It comes as Boris Johnson prepares to allow outdoor markets to open for the first time since the UK's lockdown, amid a continuing fall in cases and deaths.
