What is the difference between droplet and airborne transmission of viruses?
Droplet transmission refers to the spread of viruses contained in relatively large respiratory droplets that people project when they cough or sneeze. Because of their large size, droplets travel only a short distance (usually 3 feet or less) before they settle. Droplet transmission can occur either directly when droplets are inhaled by another person, or indirectly when droplets land on an object or surface (such as a doorknob or telephone) that are then touched by another individual. Common-cold viruses (like rhinovirus) are typically spread by droplets.
