What is the difference between a virus and a bacteria?

Professor Gizmo (Amazing Science Presentations) gives expert video advice on: What is my body made of?; Why do we get "goose bumps"?; How do I catch colds? and more...

If somebody that has a cold is near you, and they either cough some of the virus into the air, or you touch somebody and then you touch your mouth, or you rub your eye; the virus can get into your body. And once the virus is in your body, it's goning to affect the cells in your body, and the actual virus uses your cells in your body to make more viruses. When those viruses are released from you through coughing or from drinking water or something, you're going to send this virus out and somebody else may pick that virus up. Whereas a bacteria doesn't get into the cells and they use the cells for a place to reproduce. Viruses are really hard for our bodies to fight. There isn't a medication that we can take to fight a virus. But a bacteria, there are medications out there that will actually kill the bacteria. But we have a very hard time killing a virus. Our body basically has to fight the virus off itself.
