They live in the water you drink, the food you eat, and the air you breathe. Actually, people couldn't live in a world without microbes. They have been growing and multiplying in the soil, in the water, and in our bodies. But some microbes can also make people sick. The first mission on your Search for Germs is to find out about viruses.
Viruses are different than anything else found on earth.
Bacteria, on the other hand, are one-celled organisms. Outside of living cells, viruses are just collections of molecules waiting for the right environment to appear. These were illnesses caused by viruses. Antibiotics are medicine used to cure infections caused by most bacteria, but there are no medicines to cure viruses . Keep in mind, vaccines only work if you get the vaccine before you come in contact with the virus.
