The latest drive to help halt the spread of Covid-19 has been criticised by senior scientists for placing insufficient emphasis on the issues of ventilation and the need to stay apart from others.
They say the government’s
“hands, face, space” campaign stresses handwashing and the wearing of masks as key factors in controlling coronavirus transmission, while the need to keep apart has been downplayed, despite it being the single critical factor involved in the spread of Covid-19.
“As long as people keep emphasising handwashing over
aerosol transmission and ventilation, you are not going to control this pandemic,” virologist Julian Tang, of Leicester Royal Infirmary, told the
Observer.
He pointed to studies that suggest contact is the cause of transmission of the Covid-19 virus in only about 20% of cases while aerosol transmission, often in poorly ventilated rooms, accounted for the rest.
