According to CDC guidelines, how long should hands be washed?

The Centers for Disease Control and Prevention (CDC) recommends washing hands for at least 20 seconds to effectively reduce the number of germs and lower the risk of infection. This duration allows enough time to thoroughly cover all surfaces of the hands, including the front and back, between the fingers, and under the nails. Proper handwashing technique is essential, as the effectiveness does not solely depend on soap and water but also on the time spent washing. Twenty seconds is considered optimal to ensure a thorough clean, as studies show that washing for less time may not adequately remove pathogens.
