Verified step by step guidance

Understand the importance of handwashing: Handwashing is a crucial first-line defense against pathogens, helping to prevent the spread of infections.

Recognize the correct technique: Effective handwashing involves scrubbing hands thoroughly to remove dirt, bacteria, and viruses.

Identify the recommended duration: Scrubbing hands for at least 20 seconds is recommended to ensure that pathogens are effectively removed.

Consider the role of friction: Scrubbing creates friction, which helps dislodge and remove pathogens from the skin surface.

Ensure proper coverage: During the scrubbing process, make sure to cover all areas of the hands, including between fingers and under nails, to maximize pathogen removal.
