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 many places of Asia and Africa, hepatitis B has become endemic. [24] In addition, a person is sometimes infected with both hepatitis B virus (HBV) and HIV, and this population (about 2.7 million) accounts for about 1% of the total HBV infections.
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.

More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.

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.
