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.
The World Health Organization is opening up the definition of airborne pathogens – such as Covid-19, influenza and measles – to include when respiratory droplets spread through the air and ...
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 ...
Noroviruses have been called “the perfect human pathogens.” ... It spreads fast and far on surfaces and through the air in tiny droplets ... Contaminated food or liquids can also spread the ...
This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect. There are many types of pollution-related diseases, including those caused by air pollution, contaminated soil, water pollution and lacking water, sanitation and hygiene (WASH). Air pollution can be reduced.
The document concludes that the descriptor "through the air" can be used for infectious diseases where the main type of transmission involves the pathogen travelling through the air or being ...
Some infectious diseases can be spread via respiratory droplets expelled from the mouth and nose, as when a person sneezes. A respiratory droplet is a small aqueous droplet produced by exhalation, consisting of saliva or mucus and other matter derived from respiratory tract surfaces. Respiratory droplets are produced naturally as a result of ...
Relevant microbes may be viruses, bacteria, or fungi, and they may be spread through breathing, talking, coughing, sneezing, spraying of liquids, toilet flushing or any activities which generate aerosol particles or droplets or generate fomites, such as raising of dust. [13] [14]
