Using soap and water or hand sanitizer is essential in hand hygiene because it effectively removes dirt, pathogens, and contaminants from the hands. Soap works by breaking down oils and dirt, allowing them to be rinsed away, while hand sanitizer, particularly those with at least 60% alcohol, can kill a significant percentage of germs when soap and water are not available.

Proper hand hygiene is critical in healthcare settings to prevent the spread of infections and ensure the safety of patients and healthcare workers. While washing hands for a specific duration, rinsing, and using lotion may seem beneficial, the priority in hand hygiene is the method of cleansing itself. It’s important to use a suitable product that effectively targets pathogens.
