This lesson will describe something known as symbiosis and symbionts. We will explore the three main types and examples of symbiotic relationships as we define mutualism, parasitism, and commensalism.

Progress of Disease: Infection to Recovery

4. Progress of Disease: Infection to Recovery

This lesson will teach you about the five basic steps of the development of disease, what they are called, and what occurs during each phase. We'll talk about the incubation and prodromal period as well as the periods of convalescence, decline, and illness.

The Different Routes of Infectious Disease Transmission

5. The Different Routes of Infectious Disease Transmission

This lesson will discuss the different ways you can get sick. We'll discuss how pathogenic microbes can be transmitted to you or someone else as we explore horizontal and vertical transmission as well as vectors, vehicles, and fomites.

Disease Control & Prevention

6. Disease Control & Prevention

This lesson will discuss the many different ways by which people can control disease. Everything from vaccination to sterilization and beyond will be mentioned so that you can better appreciate the large arsenal of tools at our disposal.

Preventing Disease: Normal Human Flora

7. Preventing Disease: Normal Human Flora

This lesson will give you a basic understanding of what human flora is. You'll learn about the different locations of flora, such as the gut, and what mutualistic, commensal, and opportunistic microbes are.

The Spread of Disease: Endemic, Epidemic & Pandemic

8. The Spread of Disease: Endemic, Epidemic & Pandemic

This lesson will talk about what an endemic disease is and how it is different from an epidemic. We'll also discuss how an epidemic differs from something known as a pandemic. Finally, we'll look at some examples of each to help solidify these points.

Nosocomial Infections: Definition, Causes & Prevention

9. Nosocomial Infections: Definition, Causes & Prevention

In this lesson, you will learn about what a nosocomial infection is. We'll discuss, in particular, the many reasons you may get such an infection, which types of pathogens are most likely to cause one, and the most common places in your body you may acquire one.

Establishment of Disease: Entry, Dose & Virulence

10. Establishment of Disease: Entry, Dose & Virulence

This lesson will delve into what predisposes an individual to get sick. We'll talk about things like the entry, dose, and virulence of a pathogen and how they play a role in the establishment of a disease.
