What causes urticaria

First, all kinds of infection factors can cause the disease. The most common infection is caused by the virus and Staphylococcus aureus, followed by hepatitis, infectious mononucleosis and coxsackievirus; parasitic infections, such as Ascaris lumbricoides, hookworm, Schistosoma, filariasis, amoeba and Plasmodium; bacterial infections, such as acute tonsillitis, alveolar abscess, sinusitis, pustules, sepsis, etc. This is the common cause of urticaria.

Second: fish, shrimp, eggs and milk are the most common, followed by meat and some plant foods, such as strawberries, cocoa and tomatoes, which are common causes of urticaria. In addition, spoilage food is decomposed into polypeptides, and basic polypeptides are histamine release products. Protein food is absorbed in the form of peptone or polypeptide before being thoroughly digested, which can cause urticaria. This is more common in children, and it may also be caused by the different permeability of digestive tract mucosa between children and adults. In addition, the addition of food pigments, seasonings, preservatives, natural or synthetic substances in food can also cause urticaria.

Third: pollen, dust, animal dander, smoke, feathers, fungal spores, volatile chemicals (such as formaldehyde, acrolein, pyrethrum, cosmetics, etc.) and other airborne allergens are common causes of urticaria.
