Final answer:
Handwashing with soap and water is critical for preventing the spread of illnesses, including COVID-19, and is often more effective than using hand sanitizers. The CDC recommends a specific technique for washing hands, and using antimicrobial soap can have potential drawbacks such as resistant bacteria.
Step-by-step explanation:
Hand Hygiene and Its Importance
Keeping hands clean is crucial for maintaining health and preventing the spread of infections. The Centers for Disease Control and Prevention (CDC) lays out a recommended handwashing procedure:
- Wet your hands with clean running water and apply soap.
- Lather your hands, including the backs, between fingers, and under nails.
- Rinse your hands well under clean running water.
- Dry your hands using a clean towel or air dry them.
Using soap and water to wash hands is generally more effective than hand sanitizers, especially when hands are visibly dirty or greasy. This traditional method is also better at removing certain types of pathogens, including the COVID-19 virus. Although hand sanitizers with at least 60% alcohol can quickly reduce the number of microbes on hands in some situations, they do not eliminate all types of pathogens.
It is also important to note that using antimicrobial soap can lead to an increased risk of infection due to the potential for developing resistant bacteria.
Lastly, whether you're using soap and water or a hand sanitizer, it's essential to apply the correct technique to ensure all parts of the hands are thoroughly cleaned.
