Infectious diseases capable of airborne transmission include many of considerable importance both in human and veterinary medicine. The relevant infectious agent may be viruses , bacteria , or fungi , and they may be spread through breathing, talking, coughing, sneezing, raising of dust, spraying of liquids, flushing toilets , or any activities ...
Viral pneumonia is a pneumonia caused by a virus. Pneumonia is an infection that causes inflammation in one or both lungs. The pulmonary alveoli fill with fluid or pus making it difficult to breathe. [1] Pneumonia can be caused by bacteria, viruses, fungi or parasites. [1] Viruses are the most common cause of pneumonia in children, while in ...
It’s a common virus that causes illness in the upper and lower respiratory tracts, Dr. William Schaffner, a professor of infectious disease at the Vanderbilt University Medical Center, tells ...
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 ...
A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. [ 1 ] Examples are the common cold , gastroenteritis , corona , flu , pneumonia .
The common cold is an infection of the upper respiratory tract which can be caused by many different viruses. The most commonly implicated is a rhinovirus (30–80%), a type of picornavirus with 99 known serotypes. [33] Other commonly implicated viruses include coronaviruses, adenoviruses, enteroviruses, parainfluenza and RSV. [34]
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 ...
A zoonosis (/ z oʊ ˈ ɒ n ə s ɪ s, ˌ z oʊ ə ˈ n oʊ s ɪ s / ⓘ; [1] plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite, or prion) that can jump from a non-human vertebrate to a human. When humans infect non-humans, it is called reverse ...
