What is the best way to control the spread of MRSA?

  1. By taking medication

  2. Through proper handwashing

  3. By using masks

  4. By taking vancomycin

The correct answer is: Through proper handwashing

Proper handwashing is the most effective way to control the spread of MRSA (Methicillin-resistant Staphylococcus aureus). Hand hygiene is crucial in preventing the transmission of infections, particularly in healthcare settings where MRSA commonly occurs. Washing hands with soap and water, or using an alcohol-based hand sanitizer when soap is not available, removes pathogens from the skin, significantly reducing the risk of infection spread from person to person or from surfaces. While medication, including vancomycin, can treat MRSA infections, they do not prevent the transmission of the bacteria itself. Masks can help reduce the spread of respiratory infections but are not specifically effective against MRSA, which is primarily transmitted through direct skin contact or contaminated surfaces. Thus, consistent and thorough handwashing is the primary and most effective method for controlling MRSA outbreaks and ensuring safety in healthcare environments.
