Not to worry! Most germs/microbes are harmless, and some even help to keep you healthy. But some can make you very sick. Every day you come in contact with hidden germs, pretty much everywhere you go. Some of their favorite hangouts are bathrooms, kitchens, the cafeteria, the gym, and the locker room. And those are just the obvious places. They also hide on pencils (remember when you chewed on it?), remote controls or game controllers (like the one you sneezed on last week), phones, pet cages, computer keyboards, stair railings, and doorknobs pretty much anything your hands can touch.
Germs can spread when people touch things that are covered with them (like the door handle in a public restroom). These germs get on your hand and spread to other parts of your body when you touch your eyes, ears, or mouth! And they don't stop there you spread germs when you touch something or someone else. But there is one thing you can do to stop germs in their tracks. WASH YOUR HANDS!
