What You Need To Know About Infectious Disease
How Infection Works
Encountering Microbes
Microbes have inhabited the earth for billions of years and may be the earliest life forms on the planet. They live in every conceivable ecological niche—soil, water, air, plants, rocks, and animals. They even live in extreme environments such as hot springs, deep ocean thermal vents, and Antarctic ice. Indeed microbes, by sheer mass, are the earth’s most abundant life form and are highly adaptable to external forces. How does our modern lifestyle bring us into greater contact with infectious agents—the “bad” microbes? And when we encounter them, how do they get into our bodies?
