Understanding Handwashing Importance and Techniques
When considering public health and the prevention of diseases, such as COVID-19, the importance of proper handwashing cannot be overstated. To create an effective handwashing station, it is essential to have soap and water, hand sanitizer, paper towels, and a trash can. According to the CDC, the correct handwashing method involves several steps: First, hands should be wet with clean, running water, after which the tap is turned off, and soap applied. Next, scrub your hands thoroughly, including the back of your hands, between your fingers, and under your nails. Then, rinse well, ensuring that water flows from the wrist to the fingertips, which helps remove microorganisms away from the skin.
Dry hands are critical and should be done with a clean towel or an air dryer. Disposing of towels properly is also part of maintaining hygiene. It is recommended to wash hands in various circumstances, such as before and after handling food, after using the restroom, and after contact with potentially contaminated sources. For instances where soap and water are not accessible, hand sanitizer is a good alternative, although it is noted that soap and water are more effective at removing certain types of germs. Proper hand washing is a crucial behavior to adapt in order to greatly reduce the transmission of pathogens and prevent illnesses like waterborne diseases.
