Any future attempts to reduce the spread of Covid-19 should be focused on tackling close airborne transmission of the SARS-CoV-2 virus as it is considered to be the primary route for its circulation, according to experts in an editorial published in The BMJ.

Respiratory experts argue that it is now clear that the coronavirus is most likely to transmit between people at close range through inhalation, rather than through contact with surfaces or longer range airborne routes, although those routes can also be responsible.
