Why is hand hygiene emphasized in preventive care and what is the recommended duration of handwashing?

• A. Reduces the spread of infections; wash hands with soap and water for at least 20 seconds.
• B. Increases cleanliness; 5 seconds.
• C. Only necessary in sick visits; 1 minute.
• D. Hand sanitizer alone is sufficient at all times; 10 seconds.

Answer: (A)

Hand hygiene is emphasized because hands are a major way infections spread in children, families, and healthcare settings. Washing with soap and water physically removes germs from the skin, reducing the chance they will be transferred to the mouth, nose, eyes, or to other people. Doing this thoroughly for at least 20 seconds ensures all surfaces are scrubbed—between fingers, under nails, and around the wrists—so microbes are more completely removed than with a quick rinse. This duration is long enough to make a meaningful difference in preventing illness in everyday preventive care. While alcohol-based hand sanitizers are useful when hands aren’t visibly dirty, they aren’t a universal substitute for soap and water, especially when hands are contaminated or when certain pathogens are involved. The option describing at least 20 seconds of soap and water best fits the preventive care goal of reducing transmission.
