What is the most effective means in preventing the spread of germs?

The most effective means of preventing the spread of germs is regular handwashing with soap and water, especially after using the restroom and before eating. Hand sanitizer with at least 60% alcohol is a good alternative when soap and water are unavailable. Additionally, practicing good respiratory hygiene, such as covering coughs and sneezes, and maintaining physical distance in crowded places can further reduce the risk of transmission. Consistent cleaning and disinfecting of frequently-touched surfaces also play a crucial role in preventing germ spread.
