What is the proper technique for handwashing?

Washing hands with soap and water for at least 20 seconds is the most effective technique for hand hygiene. This method helps remove dirt, viruses, and bacteria from the skin, significantly reducing the likelihood of infection. The reason for the 20-second duration is that it allows enough time for the soap to break down any germs and for proper cleaning, particularly in areas that are often missed, such as between fingers, under nails, and around the wrists.

Using soap helps to lift dirt and microbes from the skin, while running water rinses them away. It's a crucial practice in preventing the spread of illnesses, especially in healthcare settings or during outbreaks of infectious diseases.

Although using alcohol-based hand sanitizer can be effective when soap and water are not available, it is not a substitute for thorough handwashing, especially when hands are visibly dirty or greasy. Rubbing hands for a brief period or rinsing them under water without soap does not adequately eliminate germs.
