Handwashing and germ prevention help students stay healthy at school, at home, and in the community. This cheat sheet explains when to wash hands, how to wash them well, and how germs spread. Students need these habits to lower the chance of getting sick or spreading illness to others.
The guide uses simple rules that are easy to remember and practice every day.
The most important idea is to wash with soap and clean running water for at least 20 seconds. Students should wash before eating, after using the bathroom, after coughing or sneezing, and after touching shared or dirty objects. Germs can spread through hands, droplets, surfaces, and close contact.
Covering coughs, keeping hands away from the face, and using hand sanitizer when soap is not available all help prevent germs from spreading.
Key Facts

Common Mistakes to Avoid
- Rinsing hands without soap is a mistake because water alone does not remove many germs as well as soap and scrubbing.
- Washing for only a few seconds is a mistake because hands need at least 20 seconds of scrubbing to clean all areas well.
- Forgetting fingertips and under nails is a mistake because germs often hide in small spaces where hands touch objects the most.
- Touching your face after touching shared surfaces is a mistake because germs can enter through your eyes, nose, or mouth.
- Using hand sanitizer on very dirty or greasy hands is a mistake because sanitizer works best on hands that are not visibly dirty.
