HIV infection process lasts for several years from the beginning of the infection. It does not occur at once. HIV infection develops in a certain way. The process includes the stages that lead a person to AIDS. However, it is essential to know that what HIV is. HIV is described as Human Deficiency Syndrome. It is a virus that enters in the body by various ways. The immune system is made up of CD4 cells. The major function of these cells is to protect the body from the various infections and diseases. The HIV enters in the body and hides in CD4 cells. It grows slowly but while doing so it starts to replicate itself.
The immune system can not recognize its existence. It continues the process of being replicated till it becomes successful in damaging the whole immune system. Eventually, HIV wins the battle with CD4 cells. It takes over the CD4 cells and badly damages the immune system. As a result of this opportunistic infections lead to attack the immune system. This is the final stage of infection where the immune system can not resist any opportunistic infections as it has been weakened severely by HIV. Every system has been damaged by the virus. The final stage comes that is called as AIDS.
Let us see that how HIV Infection Process leads to AIDS
The infection process of HIV can be broken into the four stages that are known to be the Stages of HIV infection. These stages would give the detailed information about how the virus leads to develop the AIDS. However, it is also important to see the symptoms of HIV infection that develops the disease.
Symptoms of HIV that develops in every stage of HIV infections
Flu like illness is the most common symptom. These symptoms may not appear in some cases at all. They take months or years to be appeared. There are some symptoms like, short term memory loss, weight loss that are appeared as the disease develops.

The process of HIV infection includes the stages that are given below
When an individual gets infected with the HIV the process of first stage gets started soon. The stage takes few weeks. In this stage an individual can experience the flu like symptoms. Most often these symptoms have misdiagnosed as viral infection. If a person gets tested for HIV test in this period the results will be negative. However those who feel that they might be infected should repeated the test program after six months.
This stage is called as symptom free stage as a person does not experience any symptoms. However, it does not mean that he/she is not infected. The HIV exists in blood but in low levels. They can be detectable in the blood. If an individual go through the testing the results will be positive in this stage. Though it is a symptoms free stage, HIV continuous to replicates itself in the blood.
Immune system has been damaged in this stage. So the symptoms appear on the scene. These symptoms are mild but after some time they get severe. Opportunistic infections take advantages of this situation. They attack on the immune system and make the body susceptible to AIDS.
Acquired Immune Deficiency Syndrome
This is the final stage of HIV infection where a person succumbs to AIDS. Opportunistic infections attack on immune system and take hold of it.
There is a certain HIV infection process. The process continuous till it develops AIDS.
