### Scabies, Psoriasis, and Eczema: How to Tell Them Apart
**Scabies** is a contagious skin condition caused by tiny mites called Sarcoptes scabiei. The main symptom is an intensely itchy rash, often worse at night. The rash consists of small blisters or pimple-like bumps, and you might see tiny lines on the skin where the mites have burrowed. On light skin, the rash appears red, while on dark skin, it may look greyish. Scabies can affect any part of the body but is common in certain areas in adults. In babies and young children, it can appear on the entire body, including the soles of the feet and palms of the hands. Treatment involves prescription creams or lotions that kill the mites and their eggs. Everyone in the household may need treatment, and it can take weeks for the itching to stop.
**Psoriasis** is a long-term autoimmune condition that causes the rapid buildup of skin cells, leading to scaling on the skin's surface. It is not contagious. The most common type is plaque psoriasis, which causes scaly, raised patches on the skin. On light skin, these patches appear pink or red with a silvery white scale, while on dark skin, they may look dark or purple. Other symptoms include itching and pain. Psoriasis cannot be cured, but treatments aim to reduce symptoms and improve skin appearance. Options include topical treatments, light therapy, and systemic medications.
**Eczema**, or atopic dermatitis, is a common skin condition that causes itchy rashes and irritation. The rash looks red on light skin and purplish-brown or gray on dark skin. The exact cause is unknown, but it is linked to an overactive immune response to certain triggers. Eczema is not contagious. Treatment includes moisturizing creams, topical steroids, and avoiding triggers. Severe cases may require additional treatments like immunosuppressants.
Knowing the differences between these conditions can help you identify them early and seek appropriate treatment. Always consult your doctor for a proper diagnosis and treatment plan.
