How are poison ivy or oak rashes different?

Similar: Poison ivy, poison oak and poison sumac can all cause allergic contact dermatitis. Since the rashes will all look the same, to determine which rhus plant it was, it will mean taking a walk and trying to identify the specific plant. Look but don't touch!
