Hand hygiene is the practice of keeping hands clean to prevent the spread of germs and infections. This can be achieved through regular handwashing with soap and water or using hand sanitizers that contain at least 60% alcohol. Proper hand hygiene is especially important in settings like hospitals, schools, and restaurants, where the risk of transmitting illnesses is higher. Effective handwashing involves scrubbing all parts of the hands, including between the fingers and under the nails, for at least 20 seconds. It is crucial to wash hands before eating, after using the restroom, and after coughing or sneezing. Maintaining good hand hygiene helps protect both individual health and public safety.
