World Health Organization Director-General Tedros Adhanom Ghebreyesus attends a press conference organised by the Geneva Association of United Nations Correspondents amid the COVID-19 outbreak, caused by the novel coronavirus, on July 3, 2020 at the WHO headquarters in Geneva. Fabrice COFFRINI / POOL / AFPThe WHO said Tuesday it would study fresh evidence on airborne transmission of the coronavirus, after an international group of scientists concluded it could spread far beyond two metres.
The two-metre physical distancing guideline has been a major factor in the fight against the COVID-19 pandemic, which has killed more than 538,000 people and infected over 11.6 million since the outbreak emerged in China last December. When an infected person exhales, they expel droplets. Droplets under five micrometres in size can become suspended in the air for several hours and travel up to tens of metres, they said.
“And therefore we believe that we have to be open to this evidence and understand its implications regarding the modes of transmission and also regarding the precautions that need to be taken,” she said.
