Time and mortality

The time between probable exposure to the human immunodeficiency virus (HIV, the agent that causes AIDS) and diagnosis of AIDS averages 8 to 10 years. Children seem to have a shorter incubation time, with a mean of 8 months. Worldwide, more than 75% of AIDS patients die within 2 years of diagnosis. Patients may be HIV-positive and asymptomatic for varying periods.

What causes it

AIDS is caused by infection with HIV, a retrovirus present in body fluids, such as blood and semen. Modes of HIV transmission include:

  • sexual contact, especially associated with trauma to the rectal or vaginal mucosa

How it’s treated

Although no cure exists for AIDS, signs and symptoms can be managed with treatment. Primary therapy for HIV infection includes four categories of antiretroviral drugs:

  • Reverse transcriptase inhibitors include nucleoside and non nucleoside reverse transcriptase inhibitors. Drugs in this category include abacavir (Ziagen), delavirdine (Rescriptor), didanosine, lamivudine, nevirapine (Viramune), tenofovir (Viread), and zido vudine (Retrovir).
  • Protease inhibitors include fosamprenavir (Lexiva), i ndinavir (Crixivan), ritonavir (Norvir), saquinavir (Invirase), and tipranavir ( Aptivus).
  • Fusion inhibitors include enfuvirtide (Fuzeon).
  • Integrase inhibitors include raltegravir (Isentress). Used in various combinations, these drugs are designed to inhibit HIV viral replication.
