Scientists who study the transmission of respiratory illnesses like influenza say that infections typically happen when a healthy person comes into contact with respiratory droplets from an infected person’s cough, sneeze or breath.

This simulation, created using research data from the Kyoto Institute of Technology, offers one view of what can happen when someone coughs indoors. A cough produces respiratory droplets of varying sizes. Larger droplets fall to the floor, or break up into smaller droplets.
