Often simply called an antiviral. A class of antimicrobial medication used specifically for treating diseases caused by viral infections rather than ones caused by bacteria or other infectious agents. Unlike most antibiotics, antivirals typically do not destroy their target viruses but instead inhibit their development. They are distinct from virucides. assembly The construction of the virus ...
Different viruses can infect all the organs and tissues of the body and the outcomes range from mild or no symptoms, to life-threatening diseases. [5] Humans cannot be infected by plant or insect viruses, but they are susceptible to infections with viruses from other vertebrates. These are called viral zoonoses or zoonotic infections. [6]
The human virome is the total collection of viruses in and on the human body. [1] [2] [3] Viruses in the human body may infect both human cells and other microbes such as bacteria (as with bacteriophages). [4] Some viruses cause disease, while others may be asymptomatic.
An analysis of all the publicly available viral genome sequences yielded a surprising result: humans give more viruses - about twice as many - to animals than they give to us.
Gamma phage, an example of virus particles (visualised by electron microscopy) Virology is the scientific study of biological viruses.It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they ...
A successful zoonotic 'jump' depends on human contact with an animal harboring a virus variant that is able to infect humans. In order to overcome host-range restrictions and sustain efficient human-to-human transmission, viruses originating from an animal reservoir will normally undergo mutation, genetic recombination, and reassortment. [20]
Virus classification showing major ranks This is a list of biological virus families and subfamilies. See also Comparison of computer viruses. This is an alphabetical list of biological virus families and subfamilies; it includes those families and subfamilies listed by the ICTV 2023 report. [1] For a list of individual species, see List of ...
Some viruses that infect animals, including humans, are also spread by vectors, usually blood-sucking insects, but direct transmission is more common. Some virus infections, such as norovirus and rotavirus , are spread by contaminated food and water, by hands and communal objects , and by intimate contact with another infected person, while ...
