HIV is a member of the genus Lentivirus , [12] part of the family Retroviridae . [13] 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 . [14] Lentiviruses are transmitted as single-stranded, positive- sense , enveloped RNA viruses . Upon entry into the target cell, the viral RNA genome is converted (reverse transcribed) into double-stranded DNA by a virally encoded enzyme, reverse transcriptase , that is transported along with the viral genome in the virus particle. The resulting viral DNA is then imported into the cell nucleus and integrated into the cellular DNA by a virally encoded enzyme, integrase , and host co-factors. [15] Once integrated, the virus may become latent , allowing the virus and its host cell to avoid detection by the immune system, for an indiscriminate amount of time. [16] The HIV virus can remain dormant in the human body for up to ten years after primary infection; during this period the virus does not cause symptoms. Alternatively, the integrated viral DNA may be transcribed , producing new RNA genomes and viral proteins, using host cell resources, that are packaged and released from the cell as new virus particles that will begin the replication cycle anew.
