Is acute urticaria contagious?

Acute urticaria is not contagious. Clinically referred to as wheals, acute urticaria is an allergic reaction-related disease associated with the immune system. Its causes may be related to allergies, microbial infections, stimuli from extreme temperatures, psychogenetic factors, endocrine factors, etc. Acute urticaria is not infectious but is curable and can recur. After contracting acute urticaria, it is crucial to actively identify the triggering factors to timely prevent the recurrence of urticaria.

What should not be eaten with hives?

Patients with urticaria have individual differences in their physical constitutions, and not everyone is allergic to the same foods. However, some foods have a higher likelihood of causing allergies, such as seafood, shrimp, crabs, silkworm pupae, beef, lamb, dog meat, various exotic birds and game, fruits like mango, pineapple, durian, and lemon, as well as various food additives. Additionally, spicy and stimulating foods and alcoholic beverages can aggravate allergic reactions and should be avoided as much as possible. Patients who frequently suffer from urticaria may consider undergoing allergen testing to identify which foods trigger allergic reactions. However, the allergen doses used in tests are very small and many factors can affect the results, hence the test outcomes may not fully reflect the actual situation within the patient's body. Moreover, the variety of foods tested is limited, and foods not tested could still potentially trigger urticaria in patients.

Can urticaria be contagious?

Urticaria is not contagious. Urticaria, also known as wheals or commonly referred to as hives, is caused by temporary increased vascular permeability in the skin and mucous membranes due to allergic factors, resulting in localized edema. Wheals generally subside quite quickly, typically within 24 hours. The causes of wheals, which are essentially urticaria, may include the food we eat, airborne inhalants, and skin contact with substances such as pollen, dust mites, mold mites, as well as animal dander, fur, etc. Additionally, some cases may be related to infections, and some people may have a lethal factor due to suspicious medications. Moreover, the occurrence of urticaria can also be related to other factors such as cold, heat, ultraviolet light, and mechanical stresses such as friction or pressure. Furthermore, other factors including psychological and endocrine factors can also lead to the occurrence of urticaria.

Is there a difference between measles and urticaria?

Measles and hives are two completely different skin diseases. In terms of etiology, measles is caused by a viral infection, while hives are an allergic skin disease. Clinically, measles presents with diffuse red rash all over the body, accompanied by high fever and mucous membrane catarrhal symptoms, such as red eyes, excessive eye discharge, and so on. On the other hand, hives present with wheal-like skin lesions. Wheals refer to pale red or skin-colored raised lesions that can vary in shape and are usually quite large. They typically develop very rapidly and then subside within a few hours, with most wheals disappearing within 24 hours. Hives are also usually accompanied by severe itching.
