How Does HIV Spread Out?

HIV is a retrovirus; it means the enzyme which is used in reverse transcriptase to make DNA to form its own genetic code. Similarly RNA can incorporate itself into the host cells. In order to generate an infection disease, HIV needs to cross the body's blood blockade in such a high concentration, that it leads to HIV disease. HIV consists of four stages and it should be notified that the last one is AIDS. It has been noticed that the effect of HIV is so severe that it damages the human immune system. However it is essential to know that how does HIV spread out in human body after getting infected from it.

How does the HIV infection

spread out in our body?

The process of the infection starts from the immune system cells that are called as dendritic cells. These cells could attach to and carry the virus from the infected site to the lymph nodes. As a result of this other immune system cells become infected. When HIV comes across CD4 cells a gp 120 protein that produces from HIV surface identifies the CD4 protein and sticks tightly to it. There is another viral protein called as p24 which forms a casing that surrounds HIV’s genetic material. This genetic material spreads infection in cells and produces new viruses and causes for disease.

How does HIV get transmitted?

Sexual Intercourse: This is the most general way of spreading the HIV infection. In the process of sexual intercourse HIV can enter a body through the lining of vagina, penis, rectum or mouth. Even though there are no proofs of HIV causes because of saliva, it is advised to avoid open mouthed kiss. If there are any cuts or sores in mouth, they could lead you to get infected by HIV.
