Answer:
To be put simply, bacteria can be on things that are used quite often such as toilet seats, television remotes etc. If someone does something dirty such as plant seeds in dirt and not wash their hands, the next thing they touch will have bacteria on it.

But if you wash your hands it will be gone, but if you touch your face, mouth, nose or eyes it will travel inside you, causing harm if it is a very bad type of bacteria.
