Airborne diseases can be transmitted from one individual to another through the air. The pathogens transmitted may be any kind of microbe , and they may be spread in aerosols, dust or droplets. The aerosols might be generated from sources of infection such as the bodily secretions of an infected individual, or biological wastes.
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...

The World Health Organization and around 500 experts have agreed for the first time what it means for a disease to spread through the air, in a bid to avoid the confusion early in the COVID-19 ...
If a respiratory disease spreads through inhalation, it means that people can lower their risk of infection indoors through sometimes costly methods to clean the air, such as mechanical ...
Arsenic is a naturally occurring element and can be found in food, water, or air. There are also industrial sources of arsenic, including mining and smelting. [ 8 ] " People are exposed to elevated levels of inorganic arsenic through drinking contaminated water, using contaminated water in food preparation and irrigation of food crops ...
The virus is usually spread by the fecal–oral route. [3] This may be through contaminated food or water or person-to-person contact. [3] It may also spread via contaminated surfaces or through air from the vomit of an infected person. [3] Risk factors include unsanitary food preparation and sharing close quarters. [3]
