  14. 14. 6. What is the “Window Period?” The time period between a person’s exposure & actual infection with HIV and until antibodies are detectable in the body. • After three months there are usually enough antibodies to show on an AIDS test. Nearly all people (99%) develop antibodies by THREE months. jschmied©2015
  15. 15. HIV and the Immune System 7. A person can be HIV infected and not have AIDS if the person’s immune system is intact. Often this period is from 8-10 years. Has no symptoms, person is a carrier. 8. After this period, the immune system begins to lose the fight. At this point the person has AIDS jschmied©2015

  18. 18. 10. What happens to someone with fully involved AIDS? Immune system breaks down => Hospital ?? Cause of death - a variety of normally preventable diseases. Some are: a. Pneumonia b. Toxoplasmosis c. Kaposi’s sarcoma d. Mycobacterium Avium complex e. Invasive cervical cancer jschmied©2015
  19. 19. 11. Treatment of AIDS & Life Expectancy Treatment helps people live longer. a. In 1993 = less than 7 years b. In 2006 = 20 years or more… ….if properly treated c. New drugs are the cause of the increase 2011: About 33.3 million people worldwide are infected with HIV, the virus that causes AIDS.
