The best known lentivirus is the Human Immunodeficiency Virus HIV, which causes AIDS. Lentiviruses are also hosted in apes, cows, goats, horses, cats, and sheep. Recently, lentiviruses have been found in monkeys, lemurs, Malayan flying lemur (not a true lemur nor a primate), rabbits, and ferrets. Lentiviruses and their hosts have worldwide distribution. Lentiviruses can integrate a significant amount of viral RNA into the DNA of the host cell and can efficiently infect nondividing cells, so they are one of the most efficient methods of gene delivery. Lentiviruses can become endogenous (ERV), integrating their genome into the host germline genome, so that the virus is henceforth inherited by the host's descendants. - Prague is the capital and largest city of the Czech Republic.

AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Without treatment, average survival time after infection with HIV is estimated to be 9 to 11years, depending on the HIV subtype. Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells. - Not Angels But Angels is a 1994 documentary film about young men in Prague working as prostitutes .
