Presentation Transcript

  1. Do Now • Write down what you KNOW about HIV and AIDS on the ‘K’ section of your handout, and what you would like to learn about HIV and AIDS in the ‘W’ section.

  2. Human Immunodeficiency Virus • What does HIV stand for? • What does AIDS stand for? • Acquired Immune Deficiency Syndrome • Read the ‘Theories of HIV’ article to yourself.

  3. Theories of HIV • 1) a monkey biting a human • 2) butchering of chimpanzees • 3) the production of the polio vaccination.

  4. MYTH or FACT

  5. You can get HIV from swimming in a pool with someone who is infected with HIV MYTH

  6. HIV is not spread through air-borne droplets FACT

  7. HIV is spread primarily through blood, semen, and vaginal secretions FACT

  8. You can get HIV from a mosquito bite if that mosquito has bitten an HIV-infected person MYTH

  9. You can get HIV from being sneezed on by someone who is infected. MYTH

  10. You can tell by looking at someone if they have HIV or not MYTH

  11. If partners both have HIV, they still need to have protected sex FACT

  12. I have HIV…I can’t have children MYTH

  13. HIV survives for only a short time outside the body FACT

  14. An Overview of How the Immune System Works Pathogen vs. HIV Pathogen Pictures for power point presentationhttp://www.nyhallsci.org/whataboutaids/whatis/immune/content.html:

  15. The Immune System vs. a pathogen.

  16. 1. Once a pathogen (bacteria or virus) enters the body, the immune system is alerted by the Helper (Killer) T-Cell. The job of the T-Cell is to detect any foreign substance that may be in the body that should not be there. 3. The anti-bodies beat up the pathogen until it can no longer defend itself. 2. The T-Cell than calls the B-Cells which produces antibodies. 4. The macrophage then comes in and engulfs up the weakened pathogen.

  17. The Immune System vs. HIV Virus

  18. The Immune System vs. HIV Activity • With your group, present a re-enactment of how the HIV virus defeats the immune system using poster boards with the words: SKIN, HELPER TCELL, BCELL, AND ANTIBODIES.

  19. 1. The T-Cells go to the HIV virus immediately to get rid of the problem, but the HIV virus tricks the T-Cell and attaches itself to the T-Cell.

  20. 2. The HIV Virus then proceeds to release genetic material into the T-Cell. All the while, the T-Cell believes the virus is gone. This is why sometimes it may take up to six months before HIV can be detected. 3. While this is happening, the HIV Virus destroys all signals that the T-Cell uses to sent to the B-Cell to produce antibodies.

  21. 4. The HIV Virus than finally decides to break out. 5. The T-Cell realizes there is a problem, but can no longer call the B-Cell to produce antibodies. The HIV virus continues to reproduce. Eventually the immune system can no longer defend itself.

  22. Closure • Answer journal question #1: How does the HIV pathogen take over the immune system?
