Human Immunodeficiency Virus attacks the CD4 immune cells, which are the immune system cells. CD4 cells trigger the immune system to create antibodies in order to fight off infection. As HIV destroys the CD4 cells, the function of immune system is suppressed and the affected person is not able to defend infection. As HIV reduces the CD4 cells, in your body, the person is unable to defend from infection. The immunosuppressed patient develops illness, infection and ultimately, AIDS .
Treatment for AIDS Treatment strategy for AIDS virus involves the following principles: 1. To have an effective drug that kills the HIV virus once it enters the body. 2. To create a vaccine that would prevent the disease. 3. To educate people world wide about the dangers of AIDS and how to prevent the HIV infection.
Drugs for HIV There are four essential group of drugs against AIDS:
1. Protease Inhibitors (PIs)
2. Nucleoside Reverse Transcriptase Inhibitors (NRTIs)
3. Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs)
4. Fusion Inhibitors
AID Virus is completely inactivated by treatment with
10% Household bleach
1% Nonidet P40
0.3% hydrogen peroxide
The virus is also inactivated by extremes in pH (pH 1.0 and 13.0). Virus is rapidly inactivated (<1 minute) by exposure to undiluted household bleach. Virus is readily inactivated in liquids or 10% serum by heating at 56º C for 10 minutes. Lyophilized blood products would need to be heated at 68º C for 72 hours to ensure inactivation of contaminating virus.
