Aids also known as Human Immunodeficiency Virus is caused by the virus HIV which destroys a type of defence cell in the body called a CD4 helper lymphocyte. These lymphocytes are part of the body's immune system, the defence system that fights infectious diseases. But as HIV destroys these lymphocytes, people with the virus begin to get serious infections that they normally wouldn't —that is, they become immune deficient.

This can happen via sexual intercourse, contaminated needles, blood
transfusion etc. The virus HIV infects cells of the human immune system and destroys them or stops them from working which therefore increases the vulnerability to infections and cancers to take over.
