The contagious skin disease caused by the itch mite is known as?

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

Answer: (A)

This question tests knowledge of skin diseases caused by parasitic mites. Scabies is caused by the itch mite and is highly contagious, spreading through close skin-to-skin contact or sharing bedding or clothing. It causes intense itching, especially at night, along with a pimplelike rash and tiny burrows in the skin. Commonly affected areas include the spaces between the fingers, wrists, elbows, armpits, waistline, and buttocks. The other conditions aren’t caused by a mite: ringworm is a fungal infection presenting as ring-shaped patches; impetigo is a bacterial skin infection with crusty sores; rosacea is a chronic inflammatory condition of the face. Recognizing scabies helps guide appropriate treatment and prevents spread.
