What is the most effective measure to control the spread of MRSA?

1. Using antibacterial soap

2. Proper hand washing

3. Wearing surgical masks at all times

4. Avoiding contact with infected individuals

The correct answer is: Proper hand washing

Proper hand washing is the most effective measure to control the spread of MRSA (Methicillin-resistant Staphylococcus aureus). This is because MRSA can be transmitted through direct skin-to-skin contact or by touching contaminated surfaces. By thoroughly washing hands with soap and water, or using an alcohol-based hand sanitizer when soap and water are not available, healthcare workers and individuals can remove harmful bacteria, including MRSA, from their skin. Hand hygiene is crucial in healthcare settings, where the risk of transmission is higher due to the concentration of susceptible individuals and the prevalence of infections. It reduces the likelihood of cross-contamination between patients and prevents the bacteria from spreading within facilities. Other measures, while important, may not be as consistently effective on their own. For example, using antibacterial soap can help, but its effectiveness can depend on proper technique and duration of washing. Wearing surgical masks at all times is primarily aimed at preventing respiratory droplet transmission and doesn't directly address skin contact or surfaces. Avoiding contact with infected individuals is a preventive measure, but it is not always practical in settings like hospitals, where interactions are unavoidable. Thus, comprehensive hand hygiene practices stand out as the key to controlling MRSA spread.
