Is lupus contagious?
Lupus is not contagious, not even through sexual contact. You cannot "catch" lupus from someone or "give" lupus to someone.
Lupus develops in response to a combination of factors both inside and outside the body, including hormones, genetics, and environment.
If you suspect your symptoms might be related to lupus, take the Could It Be Lupus Questionnaire.
