  What are germs?
[ 2006-05-26 11:00 ]

Did you ever wonder why or how you became sick? Chances are that germs were the source of your illness.

Germs are tiny organisms that creep into our bodies and attack our immune system.

Unable to live on their own, germs invade our bodies and steal the nutrients and energy that our bodies produce. After gobbling up all of our nutrients and vitamins the germs leave behind their own harmful wastes called toxins. These toxins are the sources of our runny noses, high fevers, diarrhea and hoarse coughs.

There are many different kinds of germs, but the four most common are: bacteria, viruses, fungi and protozoa. Each of these types of germs cause different symptoms or illnesses. For instance, while bacteria germs cause minor illnesses such as ear infections, sore throats and cavities, viruses cause more serious diseases such as chicken pox, measles and the flu.

Although germs are everywhere, most of the time we don't realize that we have germs because they are so small that you need a microscope to see them. Germs spread through the air when someone coughs or sneezes. Or germs can also appear in bodily fluids like saliva, sweat and blood. The best way to avoid getting germs is stay away from these areas where germs spread. But the most easiest way to protect yourself from germs is to wash your hands with soap and water frequently. You should always soap up your hands with suds after using the bathroom, after touching money, after playing outside or after visiting a sick friend or relative.
