Final answer:
The CDC recommends a thorough handwashing procedure involving wetting hands, applying soap, scrubbing all areas for at least 20 seconds, rinsing, and drying with a clean towel to prevent the spread of pathogens.
Step-by-step explanation:
The proper handwashing procedure is essential for preventing the spread of pathogens and maintaining good hygiene. The Centers for Disease Control and Prevention (CDC) recommends the following steps for effective handwashing:
- Wet your hands with clean, running water (warm or cold), turn off the tap, and apply soap.
- Apply about 5 mL (1 teaspoon) of liquid soap and rub it all over the hands for at least 20 seconds, including the thumb, wrist, areas between the fingers, and under the fingernails. It is suggested to use a nail brush for better cleaning.
- Rinse thoroughly, ensuring the water flows from the wrist to the fingertips to wash away microorganisms.
- Dry hands thoroughly with a clean towel or hot air blower. If possible, use a towel to turn off faucets and open doors to avoid contamination.
Proper handwashing helps prevent the spread of infectious diseases and is particularly crucial in healthcare settings. It is recommended that health-care workers wash their hands thoroughly between patient contacts and after any contact with bodily fluids or potentially infectious surfaces. For the general public, handwashing is advised before and after various activities such as food handling, eating, caring for the sick, and after using the bathroom.
