A person gets HIV when an infected person's body fluids (blood, semen, fluids from the vagina or breast milk) enter his or her bloodstream. The virus can enter the blood through linings in the mouth, anus, or sex organs (the penis and vagina), or through broken skin.
Both men and women can spread HIV. A person with HIV can feel okay and still give the virus to others. Pregnant women with HIV also can give the virus to their babies.
AIDS occurs during the last stage of infection with HIV. After your immune system starts to weaken, you are more likely to develop certain infections or illnesses, called opportunistic infections. Examples include some types of pneumonia or cancer that are more common when you have a weakened immune system.
You Cannot die from AIDS, but you can die from AIDS related illness such as cancer.
The most effective treatment for HIV is highly active antiretroviral therapy- a combination of several antiretroviral medicines that aims to control the amount of virus in your body.
Other steps you can take include keeping your immune system strong, taking medicines as prescribed, and monitoring your CD4+ (white blood cells) counts to check the effect of the virus on your immune system is the best way to live longer with HIV.
