Well, not contagious: Poison ivy is an allergic reaction not an infection. When you initially get poison ivy sap on your skin or clothing you could conceivably spread it by contact to another person. So in a sense you are "contagious". After about 24 hours the sap is no longer on your skin so it can't be spread. By the time the rash appears several days later it definitely can't be spread.
