Document Summary
The human immunodeficiency virus or hiv virus as it is commonly known is a unique type of virus (a retrovirus). The human immunodeficiency virus is a lentivirus that causes the acquired immunodeficiency syndrome, a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Recall the biological origin of hiv and the history of its discovery. Summarize the hiv cycle, including attachment, host cell entry, genome replication and integration, and virion assembly and exit. Distinguish hiv drugs based on their molecular target. 26. 5 define the four stages of hiv infection. 19. 5 million people were accessing antiretroviral therapy in 2016. 36. 7 million [30. 8 million 42. 9 million] people globally were living with hiv in 2016. 1. 8 million [1. 6 million 2. 1 million] people became newly infected with hiv in 2016. 1 million [830 000 1. 2 million] people died from aids-related illnesses in 2016.
