Scabies is caused by a small mite known as Sarcoptes scabiei. These microscopic parasites burrow into the skin, leading to intense itching and skin irritation. The life cycle of the mite includes laying eggs and creating tunnels within the outer layer of the skin, which triggers an immune response that further exacerbates the itching and discomfort. This is why understanding that scabies is caused by a mite is crucial for recognizing and treating the condition, as it differs significantly from infections caused by viruses, bacteria, or environmental factors, which involve different mechanisms and require different approaches for management and treatment.
