Difference Between Scabies and Dermatitis: Scabies and Dermatitis are both irritating skin disorders, but there is a significant difference. Scabies is a highly infectious condition caused by minute mites that burrow into the skin, lay eggs, and induce an allergic reaction. This causes extreme itching, particularly at night, as well as little raised lumps and red, irritated skin. Dermatitis, on the other hand, is a non-contagious skin condition caused by inflammation. It can be caused by genetics, environmental irritants such as soaps and detergents, or allergies. Dermatitis frequently manifests as dry, itchy, cracked skin, which may also drip fluid or create crust.

What are Scabies?
Scabies is a highly infectious skin disorder caused by microscopic mites that burrow beneath the skin. This infestation causes severe itching, particularly at night, and a red, bumpy rash. Scabies spreads by close personal contact and can afflict persons of any age.

Key Features of Scabies:
- The chief sign of scabies is severe, continuous itching, particularly at night. This is caused by an allergic response to burrowing mites and their excrement.
- Tiny, raised, red pimples emerge on the skin, usually in burrows or lines where mites have tunnelled. These lumps may develop into blisters, particularly in youngsters.
- Scabies mites love skin that is thin and heated. Fingers, wrists, elbows, genitals, buttocks, and breasts are all common sites.
- Scabies is easily transmitted by close skin-to-skin contact and sharing infected clothing or beds. Outbreaks are prevalent in crowded settings.
What is Dermatitis?
Dermatitis refers to skin irritation. It can create a red, itchy rash, as well as dryness, cracking, and blisters. Dermatitis may be classified into several forms, the most common of which being eczema. Unlike scabies, dermatitis is not contagious and can be caused by a variety of causes, including irritants, allergies, and even heredity.
