What is the difference between scabies and eczema

Scabies is a skin disease caused by a mite called scabies on the skin surface. It is also a parasitic disease that is highly contagious. Patients should be isolated in time. Eczema is a skin inflammation caused by many reasons. It can be classified into two types: acute and chronic. Eczema is also contagious to a certain extent, so contact should be avoided. Both scabies and eczema will cause rashes, and many people cannot distinguish them. So what are the specific differences between scabies and eczema?

1. Eczema

1. Acute eczema is often distributed symmetrically, and the rash has various forms, such as erythema, papules, blisters, erosions, exudate and crusts. The itching is severe and scratching may cause infection. The course of the disease is about 2-3 weeks, but it can easily become chronic and recur.

2. Chronic eczema is more common on the limbs. The symptoms include thickening and roughening of the skin, which may present as lichenification, desquamation, pigmentation, and severe itching. It often develops acutely and can last for months to years.

3. For the treatment of acute eczema, when redness and swelling are obvious or there is a lot of exudate, 3-4% boric acid solution or 5% aluminum acetate solution can be used for wet compresses. For erythema, papules or blisters, apply calamine lotion or vibrating lotion. Chronic eczema can be treated with 3-5% bran oil ointment. When the oral administration range is small and there is no exudation, dexamethasone cream or Fu Qingsong ointment can be applied externally. Oral medications include diphenhydramine, phenagar, cyproheptadine, etc. Traditional Chinese medicine also has a certain effect in treating eczema.

2. Scabies

1. Scabies, also known as itch, is a skin parasitic disease caused by scabies invading human skin. It is highly contagious and can easily spread among families and contacts. Men, women, young and old can all get sick.

2. Scabies like to invade and parasitize on areas where the skin is thin and soft, such as fingers, wrists, groin, inner thighs, etc. After burrowing into the skin, scabies mites feed on the skin's keratinous tissue, chewing out a tunnel in which they lay their eggs. Rice-sized papules, blisters, and tunnels appear on the skin. The tunnel is a thin black line, about 2-3 mm long, and there is often a small blister at the end. Scabies often live in these blisters. The skin feels extremely itchy. It is more obvious at night.
