12. Importance of Early Testing and Diagnosis Allows for early treatment to maintain and stabilize the immune system response Allows for early treatment to maintain and stabilize the immune system response Decreases risk of HIV transmission from mother to newborn baby Decreases risk of HIV transmission from mother to newborn baby Allows for risk reduction education to reduce or eliminate high-risk behavior Allows for risk reduction education to reduce or eliminate high-risk behavior

13. HIV Testing Those recently exposed should be retested at least six months after their last exposure Those recently exposed should be retested at least six months after their last exposure Screening test (EIA/ELISA) vs. confirmatory test (IFA) Screening test (EIA/ELISA) vs. confirmatory test (IFA) EIA/ELISA (Reactive) EIA/ELISA (Reactive) Repeat EIA/ELISA (Reactive) IFA (Reactive) Positive for HIV Positive for HIV

14. EIA/ELISA Test Positive Negative Run IFA Confirmation Repeat Positive End Testing Repeat ELISA Every 3 months for 1 year Negative PositiveNegativeIndeterminate Repeat at 2-4 months Repeat at 3 weeks HIV Testing No HIV Exposure Low Risk HIV Exposure High Risk Negative HIV + Repeat every 6 months for continued High risk behavior

15. Once a person is infected they are always infected Once a person is infected they are always infected Medications are available to prolong life but they do not cure the disease Medications are available to prolong life but they do not cure the disease Those who are infected are capable of infecting others without having symptoms or knowing of the infection Those who are infected are capable of infecting others without having symptoms or knowing of the infection HIV AIDS

16. HIV Risk Reduction HIV Risk Reduction Avoid unprotected sexual contact Avoid unprotected sexual contact Use barriers such as condoms. Use barriers such as condoms. Limit multiple partners by maintaining a long-term relationship with one person Limit multiple partners by maintaining a long-term relationship with one person Talk to your partner about being tested before you begin a sexual relationship Talk to your partner about being tested before you begin a sexual relationship

17. HIV Risk Reduction Avoid drug and alcohol use to maintain good judgment Avoid drug and alcohol use to maintain good judgment Don’t share needles used by others for: Don’t share needles used by others for:Drugs Tattoos Tattoos Body piercing Body piercing Avoid exposure to blood products Avoid exposure to blood products

18. Condoms Using condoms is not 100 percent effective in preventing transmission of sexually transmitted infections including HIV Condoms = Safer sex Condoms = Safer sex Condoms ≠ Safe sex Condoms ≠ Safe sex

19. Condom Use Should be used consistently and correctly Should be used consistently and correctly Should be either latex or polyurethane Should be either latex or polyurethane Should be discussed with your partner before the sexual act begins Should be discussed with your partner before the sexual act begins Should be the responsibility of both partners for the protection of both partners Should be the responsibility of both partners for the protection of both partners Male and female condoms are available Male and female condoms are available

20. People Infected with HIV People Infected with HIV Can look healthy Can look healthy Can be unaware of their infection Can be unaware of their infection Can live long productive lives when their HIV infection is managed Can live long productive lives when their HIV infection is managed Can infect people when they engage in high-risk behavior Can infect people when they engage in high-risk behavior

21. HIV Exposure and Infection Some people have had multiple exposures without becoming infected Some people have had multiple exposures without becoming infected Some people have been exposed one time and become infected Some people have been exposed one time and become infected

22. HIV and Sexually Transmitted Diseases

23. STDs increase infectivity of HIV A person co-infected with an STD and HIV may be more likely to transmit HIV due to an increase in HIV viral shedding A person co-infected with an STD and HIV may be more likely to transmit HIV due to an increase in HIV viral shedding More white blood cells, some carrying HIV, may be present in the mucosa of the genital area due to a sexually transmitted infection More white blood cells, some carrying HIV, may be present in the mucosa of the genital area due to a sexually transmitted infection

24. HIV and Sexually Transmitted Diseases STDs increase the susceptibility to HIV STDs increase the susceptibility to HIV Ulcerative and inflammatory STDs compromise the mucosal or cutaneous surfaces of the genital tract that normally act as a barrier against HIV Ulcerative and inflammatory STDs compromise the mucosal or cutaneous surfaces of the genital tract that normally act as a barrier against HIV Ulcerative STDs include: syphilis, chancroid, and genital herpes Ulcerative STDs include: syphilis, chancroid, and genital herpes Inflammatory STDs include: chlamydia, gonorrhea, and trichomoniasis Inflammatory STDs include: chlamydia, gonorrhea, and trichomoniasis

25. HIV and Sexually Transmitted Diseases HIV and Sexually Transmitted Diseases The effect of HIV infection on the immune system increases the the risk of STDs The effect of HIV infection on the immune system increases the the risk of STDs A suppressed immune response due to HIV can: I ncrease the reactivation of genital ulcers I ncrease the reactivation of genital ulcers Increase the rate of abnormal cell growth Increase the rate of abnormal cell growth Increase the difficulty in curing reactivated or newly acquired genital ulcers Increase the difficulty in curing reactivated or newly acquired genital ulcers Increase the risk of becoming infected with additional STDs Increase the risk of becoming infected with additional STDs

26. HIV Post Exposure Prophylaxis

27. HIV Occupational Exposure HIV Occupational Exposure Review facility policy and report the incident Review facility policy and report the incident Medical follow-up is necessary to determine the exposure risk and course of treatment Medical follow-up is necessary to determine the exposure risk and course of treatment Baseline and follow-up HIV testing Baseline and follow-up HIV testing Four week course of medication initiated one to two hours after exposure Four week course of medication initiated one to two hours after exposure Liver function tests to monitor medication tolerance Liver function tests to monitor medication tolerance Exposure precautions practiced Exposure precautions practiced

28. HIV Non-Occupational Exposure HIV Non-Occupational Exposure No data exists on the efficacy of antiretroviral medication after non-occupational exposures No data exists on the efficacy of antiretroviral medication after non-occupational exposures The health care provider and patient may decide to use antiretroviral therapy after weighing the risks and benefits The health care provider and patient may decide to use antiretroviral therapy after weighing the risks and benefits Antiretrovirals should not be used for those with low-risk transmissions or exposures occurring more than 72 hours after exposure Antiretrovirals should not be used for those with low-risk transmissions or exposures occurring more than 72 hours after exposure PREVENTION --- FIRST

29. HIV Non-Occupational Exposure Provider Considerations: Provider Considerations: Evaluate HIV status of patient and risk history of source patient Evaluate HIV status of patient and risk history of source patient Provide necessary medical care and counseling Provide necessary medical care and counseling Evaluate risk event and factors for exposure Evaluate risk event and factors for exposure Determine elapsed time from exposure Determine elapsed time from exposure Evaluate potential for continuous HIV exposure Evaluate potential for continuous HIV exposure Obtain informed consent for testing and treatment Obtain informed consent for testing and treatment Evaluate pregnancy status of females Evaluate pregnancy status of females Monitor for drug toxicity and acute infection Monitor for drug toxicity and acute infection
