What type of transmission-based precaution is required for MRSA and varicella?

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

Answer: (B)

For Methicillin-resistant Staphylococcus aureus (MRSA) and varicella (commonly known as chickenpox), Contact precautions are the required transmission-based precautions.

Contact precautions are necessary because both MRSA and varicella can be spread through direct contact with infected skin, wounds, or contaminated surfaces. In the case of MRSA, it is primarily spread through skin-to-skin contact or contact with contaminated objects, making it essential to prevent such transmission through the use of gloves, gowns, and proper hand hygiene. For varicella, while it also has airborne properties, the direct contact with lesions (which can be fluid-filled and contagious) necessitates Contact precautions alongside other measures.

This understanding highlights the importance of properly categorizing diseases based on how they are transmitted to implement the appropriate infection control measures effectively.
