Infected people exhale those particles as they breathe, talk, cough, sneeze, or sing.
A poster outlining precautions for airborne transmission in healthcare settings. It is intended to be posted outside rooms of patients with an infection that can spread through airborne transmission. [1] Video explainer on reducing airborne pathogen transmission indoors
Different diseases spread in different ways; some spread by only some of these routes. For instance, fomite transmission of COVID-19 is thought to be rare while aerosol, droplet and contact transmission appear to be the primary transmission modes, as of April 2021.
