The document discusses the importance of hand hygiene for preventing the spread of germs. It recommends washing hands with soap and water after activities like using the bathroom, eating, handling money, caring for someone who is sick, or cleaning. When hands are not visibly dirty, alcohol-based hand rubs can be used as they are faster and reduce bacteria.
