Yes: Urushiol is the allergen in poison oak that causes a rash to appear. Once the urushiol oil is washed off, no more rash or blisters occur. If the oil is still present on the skin, contact with that skin and urushiol could trigger a rash somewhere else or on another person. Contact with a poison oak rash will not transfer the rash to another person.
