What is lupus?

Lupus is an autoimmune (aw-toe-ih-myoon) disease. Your body’s immune system is like an army with hundreds of soldiers. The immune system’s job is to fight foreign substances in the body, like germs and viruses. But in autoimmune diseases, the immune system is out of control. It attacks healthy tissues, not germs.


You can’t catch lupus from another person. It isn’t cancer, and it isn’t related to aids.
