What Are the Symptoms of a Scabies Infection?
The symptoms of scabies include itching, rash, sores and the development of thick crusts on the skin, according to the American Academy of Dermatology. Infection can develop as a result of scratching the skin due to the presence of scabies, and in worst-case scenarios, sepsis from continual scratching can occur. Sepsis is a potentially life-threatening condition that occurs due to infection moving into the bloodstream.
The most pronounced symptom of scabies is itching; itching associated with scabies occurs mainly during the nighttime hours, according to the AAD. The itch can be so bad that it keeps the scabies-infected person up at night. Scratching the itch of scabies can result in the formation of sores, and these sores can become infected. A rash is sometimes present with scabies, and looks much like little bumps that may take on a line formation. These bumps may take on the appearance of pimples, knots beneath the skin, small bites or hives.
Scabies that is left to progress cause the formation of thick crusts on the skin, notes the AAD. At this stage, which is scabies' most severe stage, it is known as crusted scabies or Norwegian scabies. Inside the crusts are thousands of mites and their eggs. The crusts may appear to crumble when touched.
