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.
The coronavirus pandemic will cause a global recession in 2020 that could be worse than the one triggered by the global financial crisis of 2008-2009, but world economic output should recover in 2021, the International Monetary Fund said on Monday.
