Airborne transmission is complex, and hard to demonstrate unequivocally [20] but the Wells-Riley model can be used to make simple estimates of infection probability. [21] Some airborne diseases can affect non-humans. For example, Newcastle disease is an avian disease that affects many types of domestic poultry worldwide that is airborne.
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 ...

Agencies have historically required high levels of proof before calling diseases airborne, which required very stringent containment measures; the new definition says the risk of exposure and ...
The WHO concluded that airborne transmission occurs as sick people exhale pathogens that remain suspended in the air, contained in tiny particles of saliva and mucus that are inhaled by others.
The Centers for Disease Control and Prevention recommends standard, contact, and airborne precautions for patients who have illness consistent with influenza who have had recent exposure to birds ...
Diseases caused by pollution, lead to the chronic illness and deaths of about 8.4 million people each year. However, pollution receives a fraction of the interest from the global community. [ 1 ] This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect.
Some common air-borne spores. Aerobiology (from Greek ἀήρ, aēr, "air"; βίος, bios, "life"; and -λογία, -logia) is a branch of biology that studies the passive transport of organic particles, such as bacteria, fungal spores, very small insects, pollen grains and viruses. [1]
