    • 9. HIV/AIDS refers to… “Acquired Immuno Deficiency Syndrome” (AIDS) or a set of symptoms and infections resulting from the damage to the human immune system caused by the Human Immunodeficiency Virus (HIV). This condition progressively reduces the effectiveness of the immune system and leaves individuals susceptible to opportunistic infections and tumors. 9
    • 10. Basic Definitions And Meanings What is HIV? HIV is “Human Immunodeficiency Virus”,it is the virus that cause AIDS. Human means that it affects only humans and lives only in humans. The virus does not live in toilets, mosquitoes, cups, spoons, on bed sheets or towels that people with HIV might have used. Immunodeficiency refers to lack(deficiency) or breakdown of immune system. The “immune system” is the body’s resistance or the body’s defense force for fighting off infections. 10
    • 11. The virus attacks and eventually overcomes the body’s immune system. The immune system is usually able to defend the body against infections. A virus is a germ. What is AIDS? • AIDS means “Acquired Immunodeficiency Syndrome” • To acquire means to “get or develop over a period of time” • The immune system breaks down gradually 11 over time.
    • 12. It gets deficient or less and less efficient, under relentless attack by the multiplying number of virus in the body. Syndrome refers to the group or collection of signs and symptoms of indication of diseases in a person who has AIDS. HIV is the infectious stage of the condition, AIDS is the disease phase. 12
    • 13. 13
    • 14. The Origin of AIDS and HIV HIV came from a similar virus found in chimpanzees - SIV. HIV probably entered the United States around 1970.the first recognized case of AIDS was in the early 1980s. HIV is a lent virus (slow virus),which in turn is a part of a larger group of viruses known as retro virus 14
    • 15. Epidemiology Males>females Occurs in all ages and ethnic groups All areas of the country are affected In some city inner areas, as many as 50% of males are HIV positive AIDS is now the second leading cause of death for all men aged 25-44 years (Unintended injuries is #1 and heart disease is #3 for this age group) 15
    • 16. HIV Transmission • HIV enters the bloodstream through: Open Cuts Breaks in the skin Mucous membranes Direct injection 16
    • 17. Routes of Transmission of HIV Sexual Contact: Male-to-male Male-to-female or vice versa Female-to-female Blood Exposure: Injecting drug use/needle sharing Occupational exposure Transfusion of blood products Perinatal: Transmission from mother to baby Breastfeeding 17
    • 18. Routes of Transmission of HIV Occupational Transmission Health care worker/ hospital staff Laboratory workers Other routes Organ transplantation Artificial insemination Needle-prick 18
    • 19. 19
    • 20. HIV Transmission Common body fluids that are means of transmission: Blood Semen Vaginal Secretions  Breast Milk 20
    • 21. HIV in Body Fluids Blood 18,000 Semen 11,000 Vaginal Fluid 7,000 Amniotic Fluid 4,000 Saliva 1 Average number of HIV particles in 1 ml of these body fluids 21
    • 22. HIV-Infected T-Cell HIV Virus T-Cell HIV Infected T-Cell New HIV Virus 22
    • 23. Ways through which HIV/AIDS is not contacted HIV cannot reproduce outside the human body. It is not spread by: • Air or drinking water from the same pot with an infected person. • Insects: including mosquitoes. Studies conducted by researchers have shown no evidence of HIV transmission from insects. • Saliva, tears, or sweat. There is no documented case of HIV being transmitted by spitting. • Casual contact like shaking hands or sharing dishes. • Closed-mouth or “social” kissing.
    • 24. Window Period This is the period of time after becoming infected when an HIV test is negative. 90 percent of cases test positive within three months of exposure 10 percent of cases test positive within three to six months of exposure 24
    • 25. Signs And Symptoms The clinical consequence of HIV infection comprises of a spectrum ranging from an acute syndrome with primary infection to a prolonged asymptomatic stage to advanced disease. Incubation period: 2 to 10 yrs. 25
    • 26. The Acute HIV Syndrome Follows 3-6 wks following primary infection 26
    • 27. Signs And Symptoms Second phaseAsymptomatic contact Initial HIV inf. or after illness of inf. No symptoms Last 2 to 10 yrs. 27
    • 28. Signs And Symptoms Third phasePGL (Persistent Generalized Lymphadenopathy) Enlargement of lymph nodes. outside the inguinal area more than 2 areas more that 3 months 28
    • 29. Signs And Symptoms Fourth phage-Overt Manifestation of AIDS  ARC(AIDS-related complex): fever, loss of weight, anorexia, diarrhea plus PGL  Nervous system symptoms: headache, convulsion, paralysis, progressive dementia  Rare opportunistic infection.  Unusual malignant tumors.  Pneumonia. 29

    • 41. Prevention Of HIV/AIDS Risk factors Anyone of any age, race, sex or sexual orientation can be infected with HIV, but you're at greatest risk of HIV/AIDS if you: Have unprotected sex with multiple partners. Unprotected sex means having sex without using a new latex or polyurethane condom every time. Have unprotected sex with someone who is HIV-positive. Have another sexually transmitted disease, such as syphilis, herpes, Chlamydia, gonorrhea or bacterial vaginosis. Share needles during intravenous drug use. Received a blood transfusion or blood products before 1985. 41
    • 42. Prevention Of HIV/AIDS Newborns or nursing infants whose mothers tested positive for HIV but did not receive treatment also are at high risk. Fastest growing method of HIV transmission: heterosexual contact. Heterosexual transmission is easier from men to women than from women to men Risk of acquiring for men is greater if contact occurs during menstruation Uncircumcised men are more likely to be seropositive and contract HIV during sex 42
    • 43. Prevention Of HIV/AIDS If mother is HIV positive, 100% of children will test positive at birth Breast feeding increases transmission rate 43
    • 44. Prevention Of HIV/AIDS There's no vaccine to prevent HIV infection and no cure for AIDS. Prevention includes educating yourself about HIV and avoiding any behavior that allows HIV-infected fluids — blood, semen, vaginal secretions and breast milk — into your body. HIV-negative Individual prevention: Educate yourself and others. Know the HIV status of any sexual partner. Use a new latex or polyurethane condom every time you have sex. Consider male circumcision. Use a clean needle. Be cautious about blood products. Get regular screening tests. 44
    • 45. Prevention Of HIV/AIDS HIV positive individual prevention: Follow safe-sex practices. Tell your sexual partners you have HIV. If your partner is pregnant, tell her you have HIV. Tell others who need to know. Don't share needles or syringes. Don't donate blood or organs. Don't share razor blades or toothbrushes. If you're pregnant, get medical care right away. 45
