3. Introduction
Our survey is focused on one of the common chronic diseases in Malaysia, which are
HIV and AIDS. AIDS (Acquired Immunodeficiency Syndrome) is a chronic, potentially life-
threatening condition caused by a virus called HIV (Human Immunodeficiency Virus). By
damaging your immune system, HIV interferes with your body's ability to fight the
organisms that cause disease.
HIV has become one of most serious health and development challenges in Malaysia.
HIV/AIDS was first diagnosed in Malaysia in 1986 by the Ministry of Health. At the end of
2013, Malaysia was estimated to have 86,332 people living with HIV. By the end of 2013,
Malaysia had reported a cumulative 101,672 HIV cases, 20,235 AIDS cases and 16,340
deaths related to HIV/AIDS. Every day almost 10 Malaysians are diagnosed HIV positive
In this project, we need to study the understanding level of male students and female
students of Taylor’s University on HIV/AIDS. We need to compare how much male and
female students understand about HIV/AIDS. We had prepared some questions and fact
about HIV/AIDS such as, the cause of HIV/AIDS, symptoms of HIV/AIDS and effect of
HIV/AIDS. From the feedback of the students, we need to analyse and find out which gender
in Taylor’s University is more understand about HIV/AIDS.

4. Objective
The main objective of this project is to conduct a survey to investigate the
understanding level of male students and female students of Taylor’s University on
HIV/AIDS. Through the survey, we need to collect data and organize statistical data. From
the data collected, we need to analyse the data and draw conclusion from the data. Moreover,
we need to solve problems that involve various mathematical principles. We need to
understand and apply mathematical principles involved to solve the problem.

5. Methodology
Since we are targeting 300 students of Taylor’s University, we need to divide our
target into 150 male students and 150 of female students. Each of us was responsible to
survey 50 students.
We walked around every level of Block C, D and E. When we saw students who are
waiting outside the classroom or in the classroom, we walked towards them. Besides, we also
walked around every level of the library to give out the survey form. Before we gave out the
survey form, we will ask them whether they are free to help us to fill up the survey form. If
they are free, we will briefly explain the purpose of the survey to them.
One of our members is explaining
the purpose of the survey.
A student is filling up the survey
form in the classroom
The students are filling up the survey form outside the classroom.

6. The students are filling up the survey form in the library.
We spent 1 week to finish all the survey form. After we finished collecting all the
survey form, we started to do our analysis. We divided our task equally between the members.
Two members calculated all the data collected and conduct into a table. From the table, three
members analysed the table and conduct into bar chart. One of the members who are good in
designing was responsible for designing the poster.
Two of the group members is
calcultaing the data collected.
One of the group members is
analysing the data.

10. 2. What is the colourof the awarenessribbon for HIV/AIDS?
Answer: Red
Pink is most commonly associated with breast cancer awareness. Yellow is commonly seen
as a symbol to support our troops and to give us hope. However, it is also a symbol for
POW/MIA (Prisoners of War, Missing in Action), suicide prevention, bone cancer, and
endometriosis. The blue awareness ribbon is a symbol of drunk driving and child abuse.

HIV is a virus. Like all viruses, HIV cannot grow or reproduce on its own. In order to make
new copies of itself it must infect the cells of a living organism.

Condoms are the most effective way to protect against transmission of HIV and other STDs
during sex. Contraceptive pills are a kind of medication that women can take daily to prevent
pregnancy. Spermicide jelly is a birth control method that contains chemicals that stop sperm
from moving.

Answer: Yes
The only way to know if you are infected is to be tested for HIV infection. You cannot rely

Answer: All of above
Oral fluid test, blood test and urine test all are known as antibody tests. When a person is
infected with HIV, their body responds by producing special proteins to fight the infection
called antibodies. A HIV antibody test looks for these antibodies in blood, saliva or urine. If
antibodies to HIV are detected, it means a person has been infected with HIV.

25. 17. A HIV positive person canhave normal children.
Answer: Yes
Many HIV positive women are having healthy HIV negative babies by using combination
therapy (ARV’s) during pregnancy. This reduces the risk of transmission to the baby to less
than 1%, if the mother’s viral load is undetectable when the baby is born.

Answer: Yes
HIV-positive mothers can transmit HIV to their babies. This is called “mother-to-child
transmission.” (It is also called “perinatal" or "vertical transmission.”) . Mother-to-child
transmission of HIV is the most common way young children contract the virus.

baby?
Answer: Yes
There are antiretroviral drugs that can protect babies from HIV infection. When an HIV-
positive mother receives antiretroviral drugs during pregnancy, labor, and delivery; has her
baby by Caesarian section; and avoids breastfeeding, the chance of passing the infection to
her baby falls to less than 2%.

Answer: Yes
There is no cure and no vaccine for HIV/AIDS. HIV is a very small virus that has the ability
to create minor variations that evade the body's immunologic defences, which makes it
difficult to make an effective vaccine. The mutations also allow HIV to become resistant to
medications. It is important to be aware of prevention methods such as safe sex to protect
yourself.
