This dreaded disease is likely to send shivers across every spine, on its very mention. Today, it is one of the major cause of deaths across the world what makes this disease, so much dangerous, is the fact that we are still not available with any cure. In fact, even a vaccine seems to be a very distant dream. The disease has been perhaps the biggest threat to mankind, perhaps even bigger than terrorism. Anyhow, scientists all across the world are engaged in finding a cure and we a5re likely to hit some vital development in a few years.

Although AIDS and HIV are quite often interchangeably used in common language, it is interesting to note that they are different from each other. As a matter of fact, HIV refers to the virus that causes AIDS. Now, HIV is related to a subset of viruses, which are known as the retroviruses.

This retrovirus enters the body, by way of the mucous membranes or by way of blood to blood contact. After this virus enters your body, it starts weakening the immune system, which leads to the deterioration of health of the patient. This further leads to AIDS, which is the final stage of the infection.

A person is said to be suffering from AIDS, in case the cd4 counts goes down below 200. The various stages of the retroviral infection are as follows:

1. The first stage marks the arrival of the virus inside the body ad leads to the formation of various antibodies inside the human body. This is a stage, when the virus is present inside the body in undetectable limits.

2. The next stage is known as seroconversion. This is a stage in which, the human body begins to evolve a lot many antibodies, so as to fight the virus inside the body. At this phase, a patient may show flu like symptoms.

3. The next stage is the one during which the patient shows no signs whatsoever. The stage may last for several years, during which, a patient may not even realize that he/she is suffering from the disease.

4. The final stage is that of what we call AIDS. In this stage, the TCELL count drops below 200. This stage marks the final nail in the coffin, when the immune system is totally wrecked, leading to a number of infections, which ultimately lead to death, as the body is not in a position to fight back.

The disease is extremely dangerous, but can be avoided by way of a few simple precautions, i.e. safe sex, not using pre-used syringes, as well as using only properly screened blood for transfusion.
