Airborne transmission or aerosol transmission is transmission of an infectious disease through small particles suspended in the air. [2] Infectious diseases capable of airborne transmission include many of considerable importance both in human and veterinary medicine .
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 ...
Bacterial diseases – diseases caused by bacteria. Bacteriology – study of bacteria, their characteristics, growth, and role in infectious diseases. Viruses - microscopic pathogens consisting of genetic material surrounded by a protein coat, requiring living cells of host organisms to replicate. [1] Viral disease – diseases caused by viruses.
[1] [2] Both rubella, also known as German measles, and roseola are different diseases caused by unrelated viruses. [15] Symptoms usually develop 10–12 days after exposure to an infected person and last 7–10 days. [7] [8] Initial symptoms typically include fever, often greater than 40 °C (104 °F), cough, runny nose, and inflamed eyes.
Tularemia, also known as rabbit fever, is an infectious disease caused by the bacterium Francisella tularensis. [4] Symptoms may include fever , skin ulcers , and enlarged lymph nodes . [ 3 ] Occasionally, a form that results in pneumonia or a throat infection may occur.
Airborne viruses travel much like cigarette smoke, he explained. The scent will be strongest beside a smoker, but those farther away will inhale more and more smoke if they remain in the room ...
Outbreaks can be caused when a person eats an infected marmot or comes into contact with fleas carried by rats. A 2006 WHO report from an international meeting on plague cited a Chinese government disease expert as saying that most cases of the plague in China's northwest occur when hunters are contaminated while skinning infected animals.

"A cracked egg creates an entry point for contaminants, increasing the risk of contamination from airborne particles or contact with surfaces, including a person's hands," says Baker.
