What Causes Poison Ivy Dermatitis?
Poison ivy dermatitis is caused by urushiol, a potent allergen found in the plant. This oil can cause an allergic skin reaction, leading to an itchy, blistering rash. The rash usually appears where the plant has touched the skin.
Who Is at Risk?
Around 50 to 75 percent of adults in the United States are sensitive to poison ivy. People who work outdoors, like firefighters and farmers, face a higher risk. Children over eight are also commonly affected.
Symptoms and Diagnosis
Symptoms of poison ivy dermatitis include redness, swelling, and blisters that appear in a line or streak. Diagnosis is typically made by recognizing these symptoms, especially after exposure to the plant.
