Students Will Review:
This chapter helps students review the concepts in a disease origins unit of a standard human biology course. Topics covered include:
- Disease control and prevention
- Difference between infections and diseases
- The symbiotic nature of diseases
- Ways diseases are established
- How diseases progress and spread
- Types of diseases and infections
1. 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.
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 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.
6. 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.
7. 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.
8. Community Health: Definition & Care
Have you ever wondered what impact different members of your community with diverse characteristics can have on health? Or how community care is organized? Learn more about community health in this lesson.
9. What is Diphtheria? - Definition & History
Diphtheria is no longer a major concern in the developed world. But what is diphtheria, anyway? And how did scientists and physicians control this disease? Read on to find out!
10. Life Cycle of Onchocerca Volvulus
Can a fly blind you? Yes and no. If you want to find out more, then read this lesson on the life cycle of ''Onchocerca volvulus'', and a disease called onchocerciasis.
11. Life Cycle of Schistosomiasis Parasite
This lesson goes over the lifecycle of an ancient disease that affects people to this day. It's known as schistosomiasis, and you'll learn how it is that people become infected with the parasite that causes this disorder.
12. What is Taenia Solium? - Life Cycle & Cytology
This lesson provides a very detailed overview of the life cycle, morphology, and cytology of ''Taenia solium''. You'll learn exactly how it involves man and swine.
13. Loa Loa Worm: Life Cycle, Scientific Name & Facts
In this lesson we discuss the Loa Loa worm. It is one of many roundworm parasites that are transferred by fly bites. Here's some details about its life cycle, scientific name, and facts.
