HIV: [noun] either of two retroviruses that infect and destroy helper T cells of the immune system causing the marked reduction in their numbers that is diagnostic of AIDS — called also#R##N# AIDS virus, human immunodeficiency virus; compare HIV-1, HIV-2. Progress in antiretroviral therapy has considerably reduced mortality and notably improved the quality of life of individuals infected with HIV. However, drug resistance, treatment-associated toxicity, adherence to medication, and the need for lifelong therapy have remained major challenges. While the development of an HIV vaccine has remained elusive, considerable progress in developing Like other animal retroviruses, HTLV and HIV have the potential (either directly or indirectly) to promote oncogenesis, leading to the increased incidence of a variety of human cancers in the infected population (Figure 1). In addition to this “traditional” scenario, HERVs are the age-old alien viruses residing in the human genome and That said, a latently-infected cell can be reactivated, causing the cell to begin to produce HIV again. This persistence in latent HIV reservoirs is a large challenge in curing HIV infection. While ART can suppress HIV levels, it can't eliminate latent HIV reservoirs—meaning that ART cannot cure HIV infection. HIV is a retrovirus and is, therefore, able to integrate its DNA into the host genome; this fact makes the virus exceedingly difficult to eradicate with current therapies. The virus has a small Human papillomaviruses are linked to invasive cervical cancer and anogenital cancers among HIV-infected patients. Human retroviruses cause malignancy via direct effects as well as through interactions with other oncogenic herpesviruses and other viruses. Viruses are etiologically linked to approximately 20% of all malignancies worldwide. .
