"Indirect person-to-person transmission occurs when the original host sheds pathogens into the air, water, food or objects in the environment, which then infect someone else. Most airborne infections are transmitted when a cough or sneeze expels fine droplets of water, known as an aerosol, containing millions of bacteria or viruses. The aerosol droplets may be inhaled by a susceptible person, or settle on surfaces where the pathogens contaminate hands, utensils, clothing, water or food, which are then touched or consumed by someone else. Coughs and sneezes spread diseases."
