Where are germs found?

Germs are a part of everyday life. Some of them are helpful, but others are harmful and cause disease. They can be found everywhere - in our air, soil, and water. They are on our skin and in our bodies. Germs are also on the surfaces and objects that we touch.

Sometimes those germs can spread to you and make you sick. For example, there could be germs on a tv remote. You could get infected with the germs if you touch the remote and then rub your eyes or nose or eat with your hands.

How can I avoid getting germs from surfaces and objects?

To avoid becoming infected by germs from surfaces and objects, it is important to wash your hands often. But you can't wash your hands every time you touch something. So it's also important to regularly clean and disinfect surfaces and objects.

What is the difference between cleaning, sanitizing, and disinfecting?

How can I safely clean and disinfect?
