According to the U.S. Department of Health and Human Services, HIV is an infection that is transmitted by multiple causes through sexual contact, transfusions with infected blood, or by used needles that has infected blood on it (aids.gov, 2009). These cases of transmissions create high risk of an attack of the human immune system. This virus ravages through the immune system at the cellular level (aids.gov, 2009). Through research, it is believed that the virus attaches itself to what’s called a dendritic cell that are found in the areas that line the mouth, the vagina, rectum, penis, and the upper gastrointestinal tract which are linked to a type of immune system cell(aids.gov, 2009). It spreads like wildfire by the dendritic cell carrying over to the human lymph nodes that can infect other immune system cells (aids.gov, 2009). The transmission of this virus attacks cells in your body that can spread into your immune system that can harm the way your body fights against bacteria and other sicknesses.
The spread of HIV can be broken down into six main processes that repeat in a cycle to duplicate itself causing the virus to overtake the human body. It has one goal which is to infect the CD4 lymphocyte which is a T-cell that helps it reproduce and spread. As stated HIV hooks onto a T-cell then it allows itself to be released into the cell called binding and fusion (aids.gov, 2009). It then goes through a special enzyme that changes the genetic material of the virus to be integrated into the host DNA which is called reverse transcription (aids.gov, 2009). The last 3 cycles are called transcription, assembly, and budding which just ensure the life of the virus to be assimilated with other cells of the body (aids.gov, 2009).
There is currently no known cure for the HIV virus. It is very hard to stop because it attacks the white blood cell that is used to fight off viral infections which were earlier discussed called CD4 cells (DeNoon, 2010). There are multiple reasons why the HIV virus is difficult to cure is because the virus lays dormant in white blood cells and drugs do not affect them, and another reason is the rapid spread and replication process it goes through. (DeNoon, 2010). In the process in which the virus infects the cell, there are drugs that can slow the process but still does not eliminate the threat the sleeping inactive infected white blood cells in turn, when a cell is activated the infection is also activated to spread (DeNoon, 2010). Its replication process aids this dangerous virus by assimilating to the humans cell DNA that creates the easy fusion of each cell with the HIV virus as explained earlier. It is why this...
