Family Life and Sexual Health, Grade 7, Lesson 21
There are two important parts of the immune system that you need to understand to make sense of HIV.
Write on transparency: T-cell and Antibody.
A T-cell is a specific kind of a white blood cell that is the boss or “conductor” of the immune system. HIV attacks and kills T-cells.
An antibody is one of the fighters of the immune system. HIV antibodies try to kill off HIV. They do kill some. They never kill them all.
What 4 body fluids can transmit HIV?
Write on transparency: Transmit, Blood, Semen, Vaginal Fluids, Breast Milk
To transmit a germ is to pass or carry it from one person to another.
Semen is the fluid that carries sperm.
Vaginal fluid is the wetness in a woman’s vagina.
Tell me the body fluids from which people don’t catch HIV?
Write on transparency: Spit/Saliva, Pee/Urine, Sweat, Tears.
If the saliva or urine were bloody, HIV might be transmitted.
Show the transparency, HIV Lifeline, Part 2.
This is Student X. He has HIV. How might he have gotten infected? What are the three most common ways that people get infected with HIV?
If students respond with less likely or impossible means of transmission, clarify which are unlikely and which are impossible. Focus on the 3 most common means of transmission.
Write on the transparency: Had sex without a condom, Shared needle, and Got from Mom (as a baby).
Student X is 14 years old and in the 9th grade. Most students in middle school and junior high are not having sex, but Student X is. He actually got infected 1 week ago by having sex without a condom with someone who has HIV.
Imagine that this is Student X’s lifeline across your worksheet page. He gets older as we move through the numbered drawings.
