Lesson Express
Q: Why are cash machine keypads and office mugs so germy?
A: These objects are frequently touched by many people and are often damp or not cleaned regularly, making them ideal for bacteria to grow.
Q: How do bacteria spread from one object to another?
A: When people touch dirty surfaces or objects, bacteria can transfer from the surface to their hands, and then to other things they touch.
Q: Why is washing hands important for stopping the spread of germs?
A: Washing hands with soap and water removes germs like bacteria, viruses, and fungi that can spread from surfaces, food, or people. This prevents them from spreading to your face or other surfaces, helping reduce the risk of illness.
