We know that the virus's main route of transmission from one person to another is through droplets which are sneezed or coughed out by infected people. A single cough can produce up to 3,000 droplets, while a sneeze can produce as many as 10,000. These droplets then land in or are breathed into another person's airways, or fall on a surface that is touched by an uninfected person, who then touches their face - specifically their mouth, nose, ears or eyes. This method of transmission is known as "droplet spread". While it is in these droplets, the coronavirus is only in the air for a short time and travels only a short distance before it is pulled down by gravity after being coughed or sneezed out.
