« Coronavirus loses 90% of its ability to infect us within five minutes of becoming airborne, the world’s first simulations of how the virus survives in exhaled air suggest.
The findings re-emphasise the importance of short-range Covid transmission, with physical distancing and mask-wearing likely to be the most effective means of preventing infection. Ventilation, though still worthwhile, is likely to have a lesser impact. »
Nice further specification of how aerosol dissemination and ventilation in closed rooms contribute to spread of virus.
