What is the current understanding of COVID-19 transmission through the air?

The current understanding is that COVID-19 is primarily spread through close contact with an infected person, respiratory droplets, and contact with contaminated surfaces. While it is likely that COVID-19 could be spread through the air, this mode of transmission has not been definitively proven. The World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) continue to monitor and update guidance on transmission modes as new research emerges.
