The causes of acute allergic urticaria are diverse and complex, mainly including:
1. Food allergy: such as fish, shrimp, crab, meat, eggs, dairy products, and certain plant-based foods like strawberries, cocoa, and tomatoes. Some components in these foods may trigger allergic reactions.
2. Drug allergy: such as penicillin, sulfonamide drugs, and aspirin. These medications may cause an excessive immune response in the body, leading to urticaria.
3. Infections: viral infections (e.g., rubella, infectious mononucleosis), bacterial infections (e.g., acute tonsillitis, dental abscess), and parasitic infections (e.g., roundworm, hookworm) can all act as triggers.
4. Environmental factors: such as cold exposure, ultraviolet radiation, friction, and inhalation of airborne allergens like pollen and dust, which may also induce acute urticaria.
5. Other factors: including emotional stress, genetic predisposition, and autoimmune diseases, which may also lead to acute allergic urticaria under specific conditions.
