The World Health Organization's Special Envoy on Covid-19 has said the agency does not believes airborne transmission is a major cause of virus spread.
Dr David Nabarro repeated that the WHO believes the vast majority of cases are transmitted by droplets that come from the lungs and throat of an infected person when they cough and sneeze and this can be prevented by the two-metre physical distancing rule.
However, Dr Nabarro told RTÉ's News at One that the agency is keeping an open mind as to whether, in some circumstances, further transmission is possible through airborne particles.
He said that there is not a categorical body of work to say that airborne transmission is really important. Dr Nabarro said it is right for the technical teams
