Answer 1

Hands should be washed with soap and hot water for at least 20 seconds according to CDC guidelines, which is effective for preventing the spread of illnesses.

Step-by-step explanation:

For proper hand washing, hands should be washed for 20 seconds with hot water. According to the CDC, an effective method for washing hands includes using soap and running water and scrubbing your hands for at least 20 seconds. To help gauge the time, you can hum the "Happy Birthday" song from beginning to end twice, which roughly corresponds to the recommended duration. It's important to follow these recommendations, as proper hand hygiene is essential for preventing the spread of illnesses such as colds, flu, and COVID-19.
