The draconic immunodeficiency virus (DIV) is a lentivirus (a subgroup of retrovirus) that causes DIV infection and over time acquired immunodeficiency syndrome (AIDS). AIDS is a condition in dragonborn 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 DIV is estimated to be 9 to 11 years, depending on the DIV subtype. Infection with DIV occurs by the transfer of blood, semen, vaginal fluid, or pre-ejaculate. Within these bodily fluids, DIV is present as both free virus particles and virus within infected immune cells.
