1 USA HIV Infection - 2006 HIV Virology HIV virus attacks & takes over Helper T-Cells (CD-4s), an important blood factor in the body’s immune response.  HIV enters the genetic material of the T-Cell’s DNA.  The gene CCR5-Delta 32 blocks HIV from entering the Helper T-Cells in a small % of people. HIV-1 (chimp origin) is the most common HIV variety.  There are 8 major sub types of HIV-1. HIV-2 (sooty mangabey monkey origin) is the 2 nd most common variety. HIV mutates rapidly & can quickly develop resistance to anti-AIDS drugs.

2 USA HIV Infection - 2006 HIV Transmission HIV is spread primarily by:  Sexual contact with an infected person  Sharing/being stuck with a blood-infected needle, razor, toothbrush  Mother to infant –Intra-utero & during the birthing –Through breast-feeding.

3 USA HIV Infection - 2006 HIV Transmission NOT! NOT Transmitted through air, water, or insects. HIV can NOT reproduce or maintain virulence outside its host. Dried Fluids with high HIV concentrations lose 90-99% transmissibility. But 1% risk remains. There is NO known risk of casual contact HIV transmission to co-workers, clients, etc. Since 1985, personal service workers (hairdressers, barbors, cosmetologists, massage therapists, tatoo artists and acupuncturists) are governed by industry standards of care.

4 USA HIV Infection - 2006 HIV: Shall We Kiss? Casual Kissing (closed mouth; social kissing) does Not place a person at risk for HIV transmission. French or Open-mouth kissing is frisky, and may be risky, if one party is HIV-positive. Since 1997, there have been several cases of HIV transmission from Biting. (Really! Among humans…) Saliva & Tears: HIV is present in very low quanitites in AIDS patients, and considered Non-transmittable. HIV has NOT been found in sweat of HIV-positive people. HIV: Shall We Kiss?

5 USA HIV Infection - 2006 HIV Transmission Oral - Vaginal - Anal Sexual Contact :  Mouth/ Penis/Object/Hand to Vagina/Penis/Anus Other Risks: Sharing of Razors, Toothbrushes, Manicure Utensils Contributory Risk Factors:  Unprotected Sex: Lack/Inconsistent Condom Use  Multiple Sexual Partners  Frequent Change of Sexual Partners  Drug Use & Sexual Experiences  Gonorrhea & Chlamydia Infections are know to increase a person’s receptivity to HIV infection.

6 USA HIV Infection - 2006 HIV Transmission & Women Women are more vulnerable, when exposed, to becoming HIV infected than men.  Female reproductive system has larger surfaces of mucous membrane.  Male Seminal fluid & Pre-cum carry higher concentrations of HIV than do Vaginal Fluids.  In normal male-female intercourse, the thrusting action of the penis can cause small abraiding or tearing of vaginal mucous membrane, thus increasing a woman’s vulnerability to HIV.  Cultural subordination of women.

7 USA HIV Infection - 2006 HIV to AIDS Uncontrolled HIV infections compromise the human auto-immune system. A steady decrease over a 6-7 year period to a blood level of <200cm 3 of CD4’s (the master immune cell) results in a diagnosis of AIDS. Symptoms of AIDS may include:  Opportunistic infections; rashes  Colds, sore throat, fever  Chronic fatigue  Night sweats  Nausea HIV to AIDS Uncontrolled HIV infections compromise the human auto-immune system.

8 USA HIV Infection - 2006 Best Protection Against HIV Abstinence when not in a committed relationship Monogamy Safe Sex: Condom Use, Hygiene Sobriety Good Relationship Communications Get Confidential Testing: 50% of Californians have been tested at least once. And, if you are HIV-Positive –  Maintain strict adherence to your medical therapy.
