Is acute allergic urticaria contagious?

Acute allergic urticaria is not contagious. This condition is caused by an allergic reaction, usually triggered when the patient comes into contact with an allergen or consumes an allergenic food, such as pollen, dust mites, fish, or shellfish. Because allergens and allergenic foods themselves are not contagious, and individual body differences do not lead to disease transmission, individuals with acute allergic urticaria will not spread the condition to others through close contact or sharing of personal items. However, patients should still seek active treatment to avoid worsening symptoms that may affect their quality of life. During treatment, patients can use antihistamine medications under a doctor's guidance and should also take care to avoid exposure to allergens.
