Poison ivy, poison oak, and poison sumac are plants that can cause a skin rash upon contact. The red, itchy rash often shows up in lines or streaks and may cause fluid-filled blisters or large, raised hives.
The rash is caused by an allergic reaction to an oil in poison ivy, oak, and sumac. The rash may occur when your child touches the plant or clothing, pet fur, sporting gear, gardening tools, or other objects that have come in contact with one of these plants.
Your child cannot catch or spread the rash, even if he or she touches it or the blister fluid, because the plant oil will already have been absorbed or washed off the skin. The rash may seem to be spreading, but either it is still developing from earlier contact or your child has touched something that still has the plant oil on it.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
