How long does the CDC recommend washing hands during a routine handwash?

The recommendation for handwashing duration by the CDC during a routine handwash is 20 seconds. This timeframe is important because it ensures that soap is effective in removing dirt, bacteria, and viruses from the skin. A 20-second wash allows for adequate lathering and scrubbing of all parts of the hands, including the back of the hands, between fingers, and under nails, which are crucial areas where pathogens can reside.

While shorter durations such as 10 or 15 seconds may not be sufficient to achieve proper cleanliness, and 30 seconds may be more than necessary for routine handwashing, adhering to the 20-second guideline helps maximize the effectiveness of hand hygiene practices in preventing the spread of infections. Proper technique, paired with the appropriate duration, significantly enhances the overall effectiveness of handwashing as a hygiene practice.
