What is the Difference Between Hives and Scabies?

Hives and scabies are two distinct skin conditions that can cause itching and raised red spots. Here are the main differences between the two:

1. Causes: Hives are an allergic reaction caused by an exaggerated immune response to food, medication, or contact with certain substances, while scabies is an infectious disease caused by the bite of a parasite called the itch mite.
2. Appearance: Hives typically appear as pale red, raised, and extremely itchy skin rashes, whereas scabies rashes are red and may look similar to an insect bite, with skin lesions and burrow marks.
3. Location: Hives can appear anywhere on the skin, while scabies rashes tend to localize at skin folds, such as between fingers, at flexion points over wrists, elbows, and knees, and along the genitalia.
4. Diagnosis: The cause of hives is difficult to identify, and allergy testing may not be entirely fruitful. Blood counts might show elevated eosinophil counts in hives. Scabies is suspected if one of your family members is suffering from it, and skin scraping is done to confirm the diagnosis by identifying the mite.
5. Treatment: Hives are treated by avoiding contact with the causative agent, using anti-histamines, and maintaining good hygiene. Scabies is treated by maintaining hygiene, washing all clothes, towels, and bed linens, and using prescribed medications to kill the mites.

In summary, hives are caused by an allergic reaction and appear as raised, itchy rashes on the skin, while scabies is an infectious disease caused by the itch mite, resulting in red, itchy rashes at skin folds. The diagnosis and treatment methods for each condition are different.
