Scabies is a contagious skin disease caused by

• A. A fungus
• B. The itch mite
• C. A bacteria
• D. A virus

Answer: (B)

The cause of scabies is infestation by the itch mite, a tiny parasite that burrows into the skin and triggers intense itching and a pimple-like rash. This illness spreads through close physical contact and by sharing bedding or clothing. It isn’t caused by a fungus, bacteria, or virus—fungi, bacteria, and viruses lead to different kinds of infections, while scabies specifically involves a mite. Recognizing it as a mite problem guides treatment with scabicides and practical steps to prevent spread, such as washing linens and avoiding close contact until treated.
