HIV infects humans and causes damage by taking over cells in the immune system—the part of the body that usually works to fight off germs, bacteria and disease. When that happens, the body may not be able to fight off certain types of illnesses or cancers. If the infection is not detected and treated, the immune system gradually weakens and AIDS develops. HIV and AIDS are terms that are often used together, and sometimes are used interchangeably, though they are not the same thing. If you are worried about a recent potential exposure, go to the emergency room and ask for PEP post-exposure prophylaxis as soon as you can.
