Scabies is an infection caused by which of the following?

Scabies is an infestation caused by a specific type of mite known as Sarcoptes scabiei. These microscopic parasites burrow into the skin, leading to intense itching and a distinctive rash. The condition is highly contagious and is typically spread through prolonged skin-to-skin contact, making it a common concern in crowded living conditions. Understanding that scabies is caused by mites rather than bacteria, viruses, or fungi is crucial, as the treatment methods differ significantly for each type of pathogen. For instance, antibiotics are ineffective against such infestations, which require topical treatments specifically designed to eliminate the mites. This distinguishes scabies from other skin conditions that may be caused by infections from different organisms.
