HIV AND AIDS 2 HIV and AIDS If someone has HIV do they have AIDS? Most people think HIV and AIDS are the same thing, but they are not. Can someone catch AIDS or HIV by touching someone who has either one? Are homosexuals the only people who catch AIDS or HIV? People talk about it all the time but do they really know what it is and what the difference between the two are? Let’s take a look at the two conditions closer to see if we can answer some of these questions. A person’s immune system helps to fight off infections and diseases. Without the immune system a person’s body cannot fight off infections and diseases which cause people to get sick and possibly die. The body has white and red blood cells. The white blood cells fight off infections. HIV is short for human immunodeficiency virus. This virus affects the immune system by killing white blood cells which makes it hard for the body to protect itself from infections. This virus stores itself in the lymph nodes and is able to grow and reproduce there. HIV is the beginning of AIDS before developing into full blown AIDS (Acquired Immunodeficiency Syndrome). Someone can have HIV and not have AIDS yet, but eventually he/she will have full blown AIDS.

See the HIV virus infects helper T4 cells and kills them and spreads to other ones. The cells would normally activate B-cell lymphocytes but now unable to making the immune system unable to fight off diseases and infection that would have been easily fought off before. People can be tested for HIV by having an ELISA test. If the test comes back
