HIV and The Immune System By Lachlan Evans

What is HIV?
HIV otherwise know as human immunodeficiency virus, if this virus is left untreated it can cause the disease of aids (acquired immunodeficiency syndrome).
HIV is one of the many incurable diseases; this means that once you have HIV, you will have it until you die. At this moment there are no safe and effective cure for HIV. The human immune system cannot destroy it due to HIV affecting specific cells of the immune system, called CD4 cells, or T-cells. Overtime if HIV is left untreated, HIV can destroy so many of these cells that the body can’t fight of infections and disease. The helper T-cells once activated with HIV will try to create more viruses instead of doing there intended job

HIV is not spread easily; HIV can only be passed on through certain body fluids from a HIV-infected person. The list of body fluids possible to contract HIV is blood, semen (cum), pre seminal fluid (pre-cum), rectal fluids, vaginal fluids and breast milk. The body fluids listed must come into contact with a mucous membrane or a damaged tissue or HIV injected directly into your bloodstream for transmission of HIV to possibly occur. Having sexual intercourse is the biggest risk of contracting HIV; anal sex is the highest risk sexual behaviour. Vaginal sex is the second highest risk of sexual behaviour.

When our immune system kicks in and recognises the invader the immune system gets to work to produce the protective cells and antibodies to protect us against the invader. Immunisations will not cause or give you the disease, but the immune system will be alerted and will recognise the invaders should they be present at a later stage. Often when our bodies have not had any immunisations our immune response is often slow and we get sick. However after the infection without immunisations the body’s immune system remembers how to make the antibody and works similar to an immunisation just in a more severe

    In the United States two of the most common forms of transmission are sexual intercourse and sharing intravenous drug equipment. Unlike “dry” skin, mucous membranes are susceptible to HIV transmission due to the fact that this “wet” skin is not covered in protective fibers. Once the body has been exposed to HIV, the HIV will cross the epithelial layer of mucous membrane. After entering the mucous membrane HIV begins the replication process and will eventually enter the blood and lymph system and begin spreading to other parts of the body. Following initial exposure and infection the individual may begin to experience early symptoms such as fever, swollen glands, excessive fatigue, etc.…

    HIV is the human immunodeficiency virus, a serious virus that spreads through the body and attacks the immune system. The virus specifically attacks the T cells (CD4 cells) of the body. This making it so the immune system is no longer able to fight off infections and diseases as the amount of T cells decreases to an amount below the average 700 to 1500 cells/mm. (Center for Disease Control, 2015, para. 1) Once the body loses so many T cells and damages the immune system so much, the HIV infection will progress to immunodeficiency syndrome, AIDS.…
