Final answer:
Hand washing is an effective way to prevent the spread of infection by removing pathogens from your hands.
Step-by-step explanation:
Hand washing is an effective way to prevent the spread of infection because it helps remove pathogens from your hands. Pathogens are microorganisms, such as bacteria and viruses, that can cause disease. When you wash your hands with soap and warm water, you create friction that helps lift off and rinse away these harmful microorganisms.
Hand washing is especially important after using the bathroom, before eating or preparing food, and after being around sick people. Washing your hands for at least 20 seconds is recommended to ensure proper cleanliness, and you should make sure to wash all parts of your hands, including the palms, backs, fingers, and nails.
By practicing regular and thorough hand washing, you can reduce the risk of infection and help protect yourself and others from getting sick.
