What You Need To Know About Infectious Disease
How Infection Works
Types of Microbes
The microorganisms, or microbes, that can cause disease come in different forms. Viruses and bacteria are probably the most familiar because we hear so much about them. But fungi, protozoa, and helminths are also big players in the story of infectious disease. Learn more about each of these five main categories, as well as a recently discovered one: prions.

What do you know about infectious disease?
True or False: If you have a cold or the flu, taking antibiotics will help treat the infection.
