What You Need To Know About Infectious Disease
How Infection Works
Microbes occupy all of our body surfaces, including the skin, gut, and mucous membranes. Most don’t do us any harm—in fact, many help us survive. But there are certain bacteria, viruses, and other microbial life forms that can cause illness or even death. Here we learn the basics about microbes and the fascinating relationship we have with them.

True or False: Not all microbes are harmful to humans.
-
Correct!
Not all microbes are harmful to humans. In fact, many of them protect us, helping our bodies function properly and competing with harmful organisms in an eternal contest for habitable space in or on our bodies. Although the microorganisms that cause disease often receive more attention, most microorganisms do not cause illness.
