Hands

Proper hand hygiene is one of the most important sources in preventing the spread of disease because our hands come into contact with a variety of surfaces and can easily pick up and transfer germs to our bodies and others. While keeping our face clean is also important for personal hygiene, proper hand washing is key in preventing the spread of contagious illnesses. Our feet and clothing may also come into contact with germs, but they do not have the same level of contact with our face and other parts of our body as our hands do, making them less likely sources for disease transmission. Therefore, hands are the most crucial body part to keep clean for disease prevention.
