What should be the minimum duration for effective handwashing?

The minimum duration for effective handwashing is 20 seconds. This duration is recommended by health authorities such as the Centers for Disease Control and Prevention (CDC) as it has been shown to significantly reduce the presence of germs and pathogens on the hands. During these 20 seconds, it is important to thoroughly scrub all parts of the hands, including the backs of hands, between fingers, and under nails, ensuring that no area is missed.

Research indicates that washing hands for less than 20 seconds may not remove as many harmful microorganisms, leaving the hands potentially contaminated. By adhering to the 20-second guideline, individuals can better protect themselves and others from the transmission of infectious diseases, especially in settings like hospitals, schools, and food preparation areas.
