Everyone has germs. Our bodies are covered with germs that help us stay healthy. In addition to the germs that are usually present on our skin, we also pick up germs from contact with other people or objects in our surroundings. These germs are easy to pick up and transfer. In this way, they can cause you, or others, to get sick. Although people usually think that germs are spread through the air, the fact is that germs are most easily spread through hand contact.
Washing hands helps to physically remove germs by friction, and to rinse them down the drain.
