1. Frequent Handwashing: Use soap and water to wash hands for at least 20 seconds, especially before eating, after using the restroom, and after touching potentially contaminated surfaces. 2. Use of Hand Sanitizers: When soap and water are not available, use an alcohol-based hand sanitizer with at least 60% alcohol. 3. Avoid Touching Face: Refrain from touching your face, especially the eyes, nose, and mouth, to prevent the transfer of germs. 4. Clean Surfaces: Regularly disinfect frequently-touched surfaces like doorknobs, light switches, and mobile devices.
