Is AIDS a circulatory infection?

Aids is an infectious disease that AIDS virus invades the human immune defense system, making the human body lose its immune function, easily infected with diseases or malignant tumors, and leading to the death of the body. The survival time of different people infected with HIV is different, which mainly depends on the incubation period. Under normal circumstances, the incubation period of children is short, so the onset time of children will be shorter than that of adults and the survival time will be shorter. HIV mainly invades CD4T cells in human immune system, and then destroys human immune system.

First, the invasion process of HIV:

1, HIV enters the human blood circulation system through blood, and reaches various tissues and systems of the human body through the blood circulation system.

2.HIV enters the tissue system through substance exchange between the blood circulation system and the tissue.

3. HIV entering the tissue invades mononuclear macrophages swimming in the tissue and reaches lymphocytes with the swimming of mononuclear macrophages.

4.HIV fuses with CD4T cell membrane of lymphatic system, releasing the genetic material of HIV into immune cells, and using the autonomous replication system of immune cells to replicate and assemble the virus.

Second, the stages and manifestations of AIDS:

1, acute phase:

The first few days of AIDS infection, called acute phase of infection, are mainly manifested as fever, diarrhea, loss of appetite and so on.

2. Incubation period:

In the incubation period, any reaction of human immunity seems to be no different from that of normal people, and they can work and live normally.

3. Pre-AIDS:

During this period, patients will have fever, anorexia, weight loss, lymph node enlargement and other symptoms.

4, AIDS period:

In AIDS, the average survival time of patients will not exceed 9 months, which is easy to be infected with malignant tumors.
