This is a list of all virus species, including satellites and viroids. Excluded are other ranks, and other non-cellular life such as prions. Also excluded are common names and obsolete names for viruses. The taxonomy is taken from ICTV taxonomy 2022 release [1] For a list of virus families and subfamilies, see List of virus families and ...
In fact, there are so many viruses that if you combined all of Earth’s viruses, they would cover an area spanning 100 million light-years, according to a study in Nature Reviews Microbiology.
In 1988 and 2002, thousands of harbour seals were killed in Europe by phocine distemper virus. [209] Many other viruses, including caliciviruses, herpesviruses, adenoviruses and parvoviruses, circulate in marine mammal populations. [204]
Life (and viruses) on other planetary bodies have two important potential origins: from Earth or from a second genesis (life originated on that planet). Ancient viruses could have been transported from Earth to another planetary body, perhaps following a massive meteorite impact or volcanic eruption. [ 1 ]
It is estimated viruses kill 20% of the microorganism biomass each day and that there are 15 times as many viruses in the oceans as there are bacteria and archaea. Viruses are the main agents responsible for the rapid destruction of harmful algal blooms, [106] which often kill other marine life. [107]
Viruses infect all life forms; therefore the bacterial, plant, and animal cells and material in the gut also carry viruses. [6] When viruses cause harm by infecting the cells in the body, a symptomatic disease may develop. Contrary to common belief, harmful viruses may be in the minority, compared to benign viruses in the human body.

Virosphere (virus diversity, virus world, global virosphere) was coined to refer to all those places in which viruses are found or which are affected by viruses. [1] [2] However, more recently virosphere has also been used to refer to the pool of viruses that occurs in all hosts and all environments, [3] as well as viruses associated with specific types of hosts (prokaryotic virosphere, [4 ...
