HIV infection is moving inexorably towards the AIDS disease . AIDS is represented by the emergence of diseases signing a loss of patient capacity to defend itself against infectious diseases and cancers. They are called opportunistic diseases.
AIDS worse when CD4 T cells are too low to enable the organization to defend themselves infected against bacteria or viruses into contact with the body weakened, and may appear tuberculosis, toxoplasmosis, candidacies, a mononucleosis infection, shingles,. Similarly, abnormal cells may no longer be destroyed and cancer will develop more easily.
The decrease in lymphocytes will allow HIV to grow even more easily and more low defenses.
Changes in the number of viruses and defenses in the absence of antiretroviral treatment
Current treatments against HIV help reduce its propagation, the point of rendering the virus undetectable by means of blood test today. But these antiviral treatments do not cure patients infected with HIV, a body infected with HIV keep life and he will always be contaminant even though the virus seems, given blood tests, have “disappeared”.
The goal of treatment, when taken correctly, is: completely control the virus replication: the extent of the viral load in the blood shows that the virus is undetectable. restore the body’s defenses: the extent of CD4 lymphocytes in the blood shows that they are increasing
