This virus cannot be transmitted through ordinary contact such as hugging or shaking hands with someone who has the virus. It also cannot be transmitted through the air, water, or insect bites.Once the HIV virus is inside of you it destroys your CD4 cell, these are a type of white blood cell that help your body fight disease, as more of these cells are killed your immune system weakens.
