Is postpartum urticaria contagious?

Postpartum urticaria is not contagious. The occurrence of urticaria is mainly an allergic reaction to various factors such as certain foods, medications, plants, or infections. Clinically, it mainly manifests as dilation and increased permeability of small blood vessels in the skin and mucosa, resulting in skin rashes and redness. However, this condition is related to a decrease in the body's immune strength, making postpartum urticaria more likely to occur after childbirth. Postpartum urticaria has a certain hereditary nature. When postpartum urticaria occurs, one should not scratch it to prevent breaking the skin and causing secondary infections. Avoid using irritating liquids for cleansing or hot water for washing. When itching occurs, topical antipruritic agents can be applied. It is advisable to eat fresh vegetables and fruits in daily life and avoid spicy and irritating foods.

How should hives be treated?

Urticaria is divided into acute and chronic types. Antihistamines are the first choice of treatment for acute urticaria. If the condition is severe and antihistamines are ineffective, corticosteroids can be used to control the condition. The fundamental treatment for chronic urticaria is to remove the cause, and specific medications should be used under the guidance of a doctor.

Characteristics of papular urticaria

Papular urticaria is a type of allergic reaction, generally associated with contact with irritants, or bites from mosquitoes and fleas. The likelihood of occurrence increases if small animals are kept at home. Typically, small red papules or red wheals appear on localized areas of the body or extensively, with a transparent blister on top. The itching is quite severe, and the blisters are prone to bursting when scratched. Once symptoms appear, it is crucial to treat them with proper medication, and care should be taken to prevent infection if the blisters are scratched open. To prevent recurrence, it is advisable not to keep small animals at home, to frequently disinfect clothes, sheets, and duvet covers by exposing them to sunlight to eliminate mites or fleas, and to maintain a standard diet and lifestyle habits.
