Routes of Shedding

Organisms are excreted by a variety of routes. For example, organisms may be excreted from the lungs by coughing and sneezing or from the gastrointestinal tract through faeces. Organisms may also be excreted in urine, saliva, milk, pus, from the reproductive tract, or through vectors such as mosquitoes. Skin-based diseases (e.g., fungal infections) may cause shedding of organisms from the skin.
