Identifying airborne transmission as the dominant route for the spread of COVID-19

A comprehensive study shows wearing masks significantly reduces the number of infections, far more than other measures such as social distancing. It shows that airborne transmission is highly virulent and dominates the spread of COVID-19. It reveals that the difference with and without masks represents the determinant in shaping the trends of the pandemic.

Rational use of face masks in the COVID-19 pandemic

Comparison of face mask use recommendations by different health authorities. Despite the consistency in the recommendation that symptomatic individuals and those in health-care settings should use face masks, differences in recommendations were observed for the general public and community settings. Evidence that face masks can provide effective protection against respiratory infections in the community is scarce. However, face masks are widely used by medical workers as part of droplet precautions when caring for patients with respiratory infections. The study suggests vulnerable individuals avoid crowded areas and use surgical face masks rationally when exposed to high-risk areas.
