Question
Is pediatric purpura contagious?
Answer
Allergic purpura is a non-contagious allergic disease that recurs frequently, particularly in winter and spring when it tends to flare up. The causes of the disease include allergic reactions triggered by bacterial, viral, and parasitic infections, food allergies, medications, plant pollen, insect bites, and cold stimuli. In traditional Chinese medicine theory, the disease is believed to be caused by pathogenic heat damaging the blood, similar to the symptoms of yang spots. The treatment methods mainly focus on clearing heat and detoxifying, cooling blood and resolving stasis. Common formulas include the Jiawei Shijiao Dihuang decoction.
