About This Chapter
Biology: Diseases & Prevention - Chapter Summary
Through the lessons in this chapter you will review the causes and types of diseases, how they spread from person to person and how they are initially contracted. You will study the differences between the pandemic, epidemic and endemic spread of disease, how diseases may be controlled and much more. The lessons cover the material shown:
- Explanation and examples of types of diseases
- Disease vs. infection
- Theory and explanation for symbiotic interactions in disease
- Disease transmission and progression, dose, virulence and entry
- Avoiding and controlling the spread of diseases and how disease spreads
- Causes, definition and ways of preventing nosocomial infections
These bright, well-written and lively little lessons make studying a pleasure. Cleverly illustrated and delightfully animated, they still convey comprehensive and reliable information. The readily accessible online platform lets you study at any location and from any device that allows you access to the internet, and at the pace you find most comfortable. The chapter test measures your overall mastery of the information, and the dashboard helps you chart your progress and stay on track.
1. What Are the Types of Diseases?
This lesson will focus on the different types of diseases that a person may develop or contract. We'll discuss the differences between acute, chronic, primary, secondary, local, and systemic diseases.
2. The Differences Between Infection and Disease
This lesson will go over the differences between an infection and a disease. We'll cover everything from prions and infectivity to opportunistic infections and idiopathic disease. We'll also learn what the etiology of disease is and much more.
3. Symbiotic Interactions in Disease: Definition, Theory & Examples
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.
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.
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.
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.
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.
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.
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.
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.
