Which condition is a contagious skin disease transmitted by the itch mite?

• A. Impetigo
• B. Scabies
• C. Ringworm
• D. Warts

Answer: (B)

This question focuses on a contagious skin disease caused by an itch mite, scabies, which is due to the mite Sarcoptes scabiei. The mite burrows into the skin, causing intense itching—often worse at night—and a pimple-like rash with burrow tracks, commonly between the fingers, wrists, elbows, and other skin folds. Transmission occurs mainly through close skin-to-skin contact and can also happen via contaminated clothing or bedding. Impetigo is a bacterial skin infection with honey-colored crusts, ringworm is a fungal infection that forms ring-shaped scaly patches, and warts are caused by human papillomavirus; none involve an itch mite. Treatment targets eradicating the mites with medicated creams or pills, plus cleaning shared items and treating close contacts to prevent reinfestation.
