Frequently asked question: Does your own body defend itself against an HIV infection?

Your body tries to combat the HIV infection itself. Your immune system can recognize the HIV cells and wants to attack and destroy them. However, because the virus replicates itself as fast as possible, small mistakes are made and the copy always looks slightly different. That is called mutation (alteration in genetic material). The immune cells do not recognize the virus particle anymore and do not destroy it right away. This means that the virus particle can continue replicating itself undisturbed.
