Which isolation type is most associated with scabies and MRSA?

• A. Airborne
• B. Droplet
• C. Contact
• D. Protective environment

Answer: (C)

Scabies and MRSA spread mainly through direct or indirect contact, so the isolation approach that targets contact transmission is most associated with them. Scabies transmits through close skin-to-skin contact and by sharing contaminated clothing or bedding, while MRSA spreads by touching infected wounds or contact with contaminated surfaces and objects. To prevent this, contact precautions are used: gloves and gowns for anyone entering the room or handling the patient or their belongings, thorough hand hygiene, and using dedicated equipment for the patient. Airborne precautions (for things like TB) require negative pressure rooms and respirators, and droplet precautions cover larger respiratory droplets for illnesses like influenza; protective environments are for protecting highly vulnerable patients. Because scabies and MRSA spread via contact, contact isolation is the appropriate association.
