A retrovirus is a type of virus that inserts a DNA copy of its RNA genome into the DNA of a host cell that it invades, thus changing the genome of that cell. [2] After invading a host cell's cytoplasm, the virus uses its own reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro (backward).
Lentivirus is a genus of retroviruses that cause chronic and deadly diseases characterized by long incubation periods, in humans and other mammalian species. [2] The genus includes the human immunodeficiency virus (HIV), which causes AIDS.

The replication cycle of a retrovirus entails the insertion ("integration") of a DNA copy of the viral genome into the nuclear genome of the host cell.Most retroviruses infect somatic cells, but occasional infection of germline cells (cells that produce eggs and sperm) can also occur.
Positive single-stranded RNA families: three non-enveloped (Astroviridae, Caliciviridae and Picornaviridae) and four enveloped (Coronaviridae, Flaviviridae, Retroviridae and Togaviridae). All the non-enveloped families have icosahedral nucleocapsids.
Human Endogenous Retrovirus-W (HERV-W) is a family of Human Endogenous Retroviruses (HERVs).. HERVs are part of a superfamily of repetitive and transposable elements. ...
HIV is a member of the genus Lentivirus, [15] part of the family Retroviridae. [16] Lentiviruses have many morphologies and biological properties in common. Many species are infected by lentiviruses, which are characteristically responsible for long-duration illnesses with a long incubation period. [17]
Gammaretrovirus is a part of the retroviridae family. Gammaretroviruses are considered zoonotic viruses because they are found in many different mammalian species, such as mice, cats, pigs, primates, cows, and birds. However, bats are the primary reservoir for many gammaretroviruses.
