What type of disorder is scabies?

Scabies is classified as a parasitic infestation because it is caused by the Sarcoptes scabiei mite, which burrows into the skin and causes intense itching and irritation. This mite is a small parasitic organism that lives on the host's skin, feeding on dead skin cells and creating tunnels within the epidermis. The primary symptom of scabies is a rash, which can develop due to the body’s allergic reaction to the mites, their eggs, and their waste. Understanding this classification is important for effective treatment, as it requires specific medications that target the mites rather than antifungal, antibacterial, or antiviral treatments, which are effective against their respective types of infections. This distinction is crucial for both diagnosis and management in clinical practice.
