Step-by-step explanation:
The CDC recommends that you should scrub your hands for at least 20 seconds during hand washing. This guideline is relevant for the general public and is especially important in a clinical or health-care setting.
The process of hand washing involves five important steps. Initially, the hands should be wet with clean, running water, followed by the application of soap. Later, hands should be scrubbed for a minimum of 20 seconds, taking care to clean under nails, between fingers, and up to the wrists. Following this, hands should be thoroughly rinsed under the clean, running water. The final step is to dry hands using a clean towel or air dry them.
This hand washing practice is crucial to public health as it helps in preventing the spread of disease causing germs. It's furthermore recommended before, during, and after food handling, before eating, before and after interacting with the ill, and after potentially contaminating activities such as using the toilet or handling garbage.
