HIV Infection and AIDS

HIV infection and AIDS both are correlated to each other. Before going to discuss about both these terms it would be better to understand the conception of HIV and AIDS. HIV stands for Human Deficiency Virus. It is a kind of virus that attacks on immune system. It exists in the CD4 cells. CD4 cells are soldier cells that resist the diseases and infections and thus keep the body protected from these invaders. However, CD4 cells can not recognize the existence of the virus as it hides in these cells. It develops gradually and replicates itself in order to damage the immune system. Once it develops completely, it takes over the immune system and destroys it completely. At the end a person becomes a victim of AIDS. Moreover when a person leads to this stage opportunistic infections attack on the immune system. They take the advantage of weakened or destroyed immune system.

On the other hand the word AIDS represents as Acquired immune deficiency syndrome. It is the advanced stage of HIV infection. When a person develops this stage he/she cannot go back to the primary stage that is known as HIV infection though he/she seems better. There are certain stages of HIV infection as a person develops these stages he/she reaches near to AIDS that is the last stage of HIV infection.

Let us see how HIV and AIDS are correlated

In order to see the correlation of these terms it would be better to see that how HIV infection turns into the AIDS. For that we will have to study the symptoms of HIV infection that once developed leads to AIDS. The symptoms of HIV can be randomly classified into two groups. The first one is early symptoms that appear when a person gets infected with HIV. The other is common symptoms that take eight to ten years to be seen.

Early Symptoms of HIV

These symptoms resemblance to flu like illness. It may possible that they do not appear in some cases at all. These symptoms develop in months or years. When these symptoms develop the symptoms like extreme fatigue, short term memory loss, weight loss etc. can be seen in infected person.

The early symptoms include

Some common symptoms of HIV

How HIV becomes AIDS

There are four stages of HIV infection. These stages take several years to be developed. The process can be classified into four stages that are primary, asymptomatic, symptomatic, and AIDS. It is necessary to know about that in what stage a person is as it would be helpful for a physician to decide the treatment plan for the disease.

Stages of HIV infection

Primary stage

It is the first stage of HIV infection. When a person gets infected with HIV infection the stage starts soon after that. The stage continues for few weeks and an infected person can experience the symptoms like flu like illness. Generally many people do not undergo with treatment because the symptoms resemblance to sickness or fever. If a person goes through treatment, it is often misdiagnosed with a viral infection. The HIV test results appear to be negative in this period. So it is advisable for those who think that they may be having HIV infection should repeated the test program after six months.

Asymptomatic HIV

In this stage a person becomes symptoms free. HIV finds in low extent in the blood but it can be detectable. Moreover, the HIV test results appear to be positive in this period if it is performed. Though the symptoms are not visible, but HIV continuously reproduced in the blood. The period can be shorter or longer.

Symptomatic HIV

In this stage the immune system is damaged by HIV. As a result of this the symptoms begin to appear. At the beginning symptoms are mild but later on they become severe. Opportunistic infection attack on immune system in this period as immune system is no longer resisting them.

Acquired Immune Deficiency Syndrome

This one is last stage and a person gets diagnosed with AIDS. Opportunistic infections can be seen clearly in this stage. A person cannot get back to the primary stage after getting developed AIDS.

There is a certain correlation between HIV infection and AIDS. The given stuff would help you to understand this correlation.
