Under what circumstances should hand washing be performed?

Hand washing is a critical practice in maintaining hygiene and preventing the spread of illness. It should be performed under multiple specified situations to ensure that hands are clean and free from harmful pathogens. Key moments for hand washing include before and after preparing food, before eating, after using the restroom, after coughing or sneezing, and when hands are visibly dirty. By washing hands in these various circumstances, individuals can significantly reduce the risk of cross-contamination and the transmission of infectious diseases, thereby safeguarding both personal health and the health of others.

The emphasis on multiple situations reflects the importance of consistent hand hygiene as part of a broader approach to health and safety, particularly in settings where health vulnerabilities are present.
