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 ...
Microorganisms constitute more than 90% of the biomass in the sea. It is estimated that viruses kill approximately 20% of this biomass each day and that there are 10 to 15 times as many viruses in the oceans as there are bacteria and archaea. [205]
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.

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 years when there is a new strain of the virus, there can be 50% more norovirus illness.” ...
[21] [22] According to the World Health Organization, approximately 10 million new TB infections occur every year, and 1.5 million people die from it each year – making it the world's top infectious killer (before COVID-19 pandemic). [21] However, there is a lack of sources which describe major TB epidemics with definite time spans and death ...
As for the common cold, there are over 200 viruses that can cause it. The period of infectiousness depends on the virus and on the health of the individual infected, but generally follows a ...
Many latent and asymptomatic viruses are present in the human body all the time. 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.
