9 Human Papillomavirus ________________-__Or_________– is a virus that can cause genital warts or asymptomatic infection A _______ test and other medical examinations may detect changes associated with HPV Most cases appear to be temporary and are probably cleared by the immune system

10 Genital Warts These are pink or reddish warts with cauliflower like tops that appear on the genitals, the vagina, or the cervix one to three months after infection from HPV Diagnosis is determined by a _______ worker by examination of the warts

11 Genital Warts Examination & treatment is essential, because once you have acquired the virus you have it for _________

12 Chlamydia Chlamydia – is a bacterial infection that affects the reproductive organs of both males and females It is ______________ & often goes undetected It is diagnosed by laboratory examinations of secretions It can be treated with ____________

20 AIDS / HIV __________ – Acquired Immune Deficiency Syndrome
__________ – Human Immunodeficiency Virus

21 How HIV Attacks Cells 1. HIV attaches to cell surface
2. Virus core enters cell and goes to nucleus 3. Virus makes a copy of its genetic material 4. New virus assembles at cell surface 5. New virus breaks away from host cell

22 HIV & the human body As the virus enters your body and takes over cells, it reproduces and looks to decrease the number of T cells. Therefore making the immune system more susceptible to disease ________________ Infections are infections that occur in individuals who do not have healthy immune systems

23 How HIV is transmitted HIV can only be transmitted 1 of ___ ways
Through Blood ___________ Vaginal Secretion ______________

24 How is HIV transmitted HIV enters cells of the ___________ system, where it makes more viruses that break away and attack other cells

28 Stages of HIV infection
Stage 2 – ________________ Stage the stage in which a person infected with HIV has symptoms as a result of a severe drop in immune cells Such symptoms may include swollen glands, weight loss, and yeast infections

29 Stages of HIV infection
Final Stage – __________, during the ladder stage of HIV infection, more serious symptoms appear until the infection meets the official definition of AIDS

30 Detecting HIV There are basically _____ tests used in detecting HIV
_______________________ test is a test that screens for the presence of HIV antibodies in the blood

31 Detecting HIV The _________ test can give inaccurate results 2 reasons include 1. Developing antibodies takes time – perhaps the virus has not yet been completely developed in the body. Remember it could take many weeks (3-4 weeks) to get an accurate reading

32 Detecting HIV 2. Certain health conditions – such as hemophilia, hepatitis, and pregnancy can cause false readings

33 Detecting HIV If the EIA test is positive then they will perform it a second time just to be sure that the results are accurate. If this is the case then they move onto another test called the _______________ Test

34 Detecting HIV _____________________is the most common confirmation test for HIV in the United States If this test comes back positive that means that all 3 tests have came back positive and then the person is determined to have HIV or HIV-Positive
