A. Warm-up Game
B. The Difference Between HIV and AIDS
Explain the following points:
• Technically, people do not die from
AIDS or from HIV.
• HIV is a virus that attacks the
immune system, so that the immune system cannot protect the body.
• Once HIV has killed enough of the
immune system and diseases have started to attack the body, the person
is said to have AIDS.
• AIDS is a condition in which the
immune system is so weakened by HIV that it cannot protect itself from
other diseases.
AIDS: Aquired Immune Deficiency
Syndrome
UKIMWI: Ukosefu Wa Kinga Mwilini
• People with AIDS can get many kinds
of diseases easily because their body cannot fight them.
• These diseases are called “opportunistic
infections” because they take the opportunity to attack the immune system
when it is weak.
• In order to understand how HIV affects
the body and progresses into AIDS we are going to act out the immune system.
C. Immune-System Role Play
1. What is the immune system?
The immune system is the system in
our body that protects us from diseases. The immune system fights
diseases as soon as they enter the body.
2. How does the immune system work?
a) The immune system has many
kinds of white blood cells, each with an important job. Here are
some of the cells and their jobs:
T4 Cells (helper cells/chembechembe saidizi): The T4 cells order other cells to fight antigens.
Antigens: Germs that cause disease. They could be virus, bacteria, fungus or any other type of germ.
T8 Cells/ Killer cells: When the T4 cell alerts them to the danger, T8 cells attack antigens when they enter the body and stop disease.
B cell: When the T4 cell alerts them to the danger, this cell makes antibodies.
Antibodies/Kingamwili: Antibodies learn
to recognize antigens and kill them when they enter the body.
b) How does the immune system work without HIV?
• When an antigen enters the body,
the T4 cells see it and tell the B cells and the T8 cells to fight it.
• The B cells make antibodies which
will learn to recognize the antigen in the future and will attack it.
• The T8 cells kill the antigen.
• When the antigen tries to enter
again the antibodies recognize it and help the T8 cells to kill it.
c) How does the immune system work
with HIV?
• When HIV enters the body it takes
over the T4 cells, multiplies inside them, and kills them.
• The T4 cells are not able to warn
the other cells when diseases enter the body.
• When an antigen enters the body,
the T8 cells and the B cells don’t recognize it and they let it attack
the body. The body gets very sick since it cannot fight disease.
d) Acting out the immune system:
The following roles are assigned and
the immune system is acted out both before and after HIV attacks it.
• T4 cell
• B cell
• T8 cell
• Antibody
• Antigen
• HIV
D. Progression of HIV into AIDS
HIV turns into AIDS when a certain
amount of the T4 cells have been killed. Once a person has below
a certain amount of T4 cells and has had opportunistic infections, that
person is said to have AIDS. When a person is infected with HIV the
disease goes through the following stages:
1. Window period
After a person has first been infected
with HIV, they have not yet developed antibodies. They may test negative
for HIV because the test measures antibodies, not the virus. This
period can last 3-6 months. During this time the person may feel
flu-like symptoms and they can easily infect another person, even though
they would test negative for HIV.
2. Incubation Period
This is the time when HIV antibodies
develop and try to fight the disease. During this time, a person
will test positive for HIV and can transmit the virus to others, but they
may not look or feel sick. This period can last longer than 15 years,
but usually lasts between 5 and 10 years. This period can be prolonged
by a healthy lifestyle which includes: proper rest, exercise, good
nutrition, not smoking or drinking, emotional well-being, and getting
early treatment for any diseases that occur.
3. AIDS
After a while the HIV kills enough
T4 cells and the body develops AIDS. During this time a person will
get sick very easily with diseases their body would normally be able to
fight off.
Draw progression chart on board.
Have participants put the following symptoms in their correct place in
the progression of the illness. Stress that the way HIV develops
is different for each person depending on their body and their lifestyle.
If a person with HIV is healthy, he or she can live a lot longer before
developing AIDS.
Early symptoms:
Weight loss/ Kupungua uzito
Cough / Kukohoa
Chronic Diarrhea /Kuharisha sana
Yeast infections
Chills /Baridi
Opportunistic Infections:
Tuberculosis (TB) /Kifua kikuu
Pneumonia /Baridi yabisi
Shingles /Upele
Kaposi Sarcoma
Toxoplasmosis
Cervical Cancer/ Saratani ya kizazi
D. Co-factor tug of war:
Have half of the group stand in a
line and the other half stand in a line facing the other direction.
One side of the group represents things that will help a person who is
HIV positive to delay the onset of AIDS (a healthy lifestyle). The
other side represents things which make a person who is HIV positive get
AIDS faster (an unhealthy lifestyle). The two sides hold on to the
waist of the person in front of them and pull on them, trying to see if
they can make the other side topple over. Afterwards point out to
the group that it is important for people who think they could be HIV positive
to be tested early. If they find out they are positive there is a
lot they can do to delay the onset of AIDS.
