A year into the pandemic, the evidence is now clear. The coronavirus SARS-CoV-2 is transmitted predominantly through the air — by people talking and breathing out large droplets and small particles called aerosols. Catching the virus from surfaces — although plausible — seems to be rare (E. Goldman Lancet Infect. Dis. 20, 892–893; 2020).
Despite this, some public-health agencies still emphasize that surfaces pose a threat and should be disinfected frequently. The result is a confusing public message when clear guidance is needed on how to prioritize efforts to prevent the virus spreading.
