A single
sneeze releases about 30,000 droplets, with droplets traveling at up to 200 miles per hour. Most droplets are small and travel great distances (easily across a room). If a person is infected, the droplets in a single cough or sneeze may contain as many as 200,000,000 (two hundred million) virus particles, which can all be dispersed into the environment around them.
A breath: A single breath releases 50 - 5000 droplets.
