What are the most common symptoms of scabies?

The most common symptoms of scabies include intense itching and a pimple-like skin rash. Scabies is caused by a mite that burrows into the skin, leading to an immune response characterized by itching, which often becomes more severe at night. The pimple-like rash is a result of this irritation and the body's response to the presence of the mites and their waste products. This combination of symptoms distinguishes scabies from other skin conditions and highlights the specific nature of the infestation.

In the context of scabies, symptoms such as dry skin and rashes can be associated with various other skin ailments but do not specifically represent the unique presentation of scabies. Fever and fatigue are more general symptoms that could signify a wider range of infections or illnesses but are not directly linked to scabies. Additionally, swelling and redness might occur as a secondary response to scratching or infection but again do not encapsulate the hallmark symptoms of scabies. Thus, the intense itching coupled with the characteristic skin rash makes option B the most accurate description of scabies symptoms.
