Before you read the poster below, discuss what you know about HIV/AIDS with your classmates. Make a list of words that you might come across in this poster.
HIV/AIDS:ARE YOU AT RISK?
     HIV is a virus. A virus is a very small living thing that causes disease. There are many different viruses, for example, the flu virus or the SARS virus. HIV weakens a person's  immune system; that is, the part of the body that fights disease. You can have HIV in your  blood for a long time, but eventually HIV will damage your immune system so much that you body can no longer fight disease. This stage of the illness is called AIDS. If you develop AIDS, your chances of survival are very small.
     HIV is spread through blood or the fluid that the body makes during sex. For a person  to become infected, blood or sexual fluid that carries the virus, has to get inside the body through broken skin or by injection. One day scientists will find a cure for HIV/AIDS.
Until that happens, you need to protect yourself. Here are some things you can do to make sure you stay safe.
If you inject drugs:
do not share your needle with anyone else. Blood from another person can stay on or in the needle. If a person has HIV and you use the same needle, you could inject the virus into your own blood.
do not share anything else that a person has used while injecting drugs.Blood could have spilt on it.
If you have sex with a male or a female:
use a condom. This will prevent sexual fluid passing from one person to another.
The following statements are NOT true.
A person cannot get HIV the first time they have sex.WRONG. If one sexual partner has HIV, the other partner could become infected.
You can tell by looking at someone whether or not they have HIV.WRONG. Many people carrying HIV look perfectly healthy. It is only when the disease has progressed to AIDS that a person begins to look sick.
Only homosexuals get AIDS.WRONG. Anyone who has sex with a person infected with H1V/AIDS risks getting the virus. Women are slightly more likely to become infected than men.
If you hug, touch or kiss someone with AIDS or visit them in their home, you will get HIV/AIDS.WRONG.You can only get the disease from blood or sexual fluid.Unfortunately, people with HIV sometimes lose their friends because of prejudice.Many people are afraid that they will get HIV/AIDS from those infected with HIV!AIDS. For the same reason, some AIDS patients cannot find anyone to look after them when they are sick.
     You can get HIV/AIDS from mosquitoes.WRONG. There is no evidence of this.
