It takes the most important CD4T lymphocytes in the human immune system as the main target. After massive destruction of these cells, the human body loses most of it. Immune function, high mortality due to disease. However, the HIV virus has a very poor ability to survive outside the body, is intolerant to high temperatures, and has low resistance. It is not easy to survive without the human body. It is often widespread in the blood, semen, vaginal secretions, saliva, urine, milk, cerebrospinal fluid and nerves of patients. In the brain tissue of the symptomatic person.
