Poison ivy is the most common allergy in the United States, affecting about 50 million people every year. The rash from poison ivy is caused by an allergic reaction to urushiol, an oily substance in the leaves, stems and roots of poison ivy, through direct contact. Urushiol is also found in poison oak and poison sumac, which means the rash can be contracted by interacting with any of the three plants.
Other than direct contact, poison ivy can spread through anything that touches the oil such as skin, pet fur, clothing etc. However, blister fluid from a rash will not cause spreading.
The best way to avoid getting poison ivy is to wash clothes, gardening tools or skin that may have touched the plant immediately upon returning indoors.
Most causes of poison ivy can be treated at home with lotions and cool baths. However, if your rash is widespread on the face or genitals, a prescription medication may be needed.
