Chapter Four talked about the differences between communicable diseases which are infectious and concummunicable diseases which are noninfectious, which catorgoize as acute or cronic. The chapter simplifided these differences by using the chain of infection model. It shows the breaking of one or more links in the chain which can interrupt the transmission of a disease. This chapter helped us to understand the differences that there were with the communicable and the noncommunicable diseases, in order for a communicable disease to occur, a host, agent and environment must be present and for a noncommunicable disease are caused by different kinds of things or etiologies, in order to understand this better there is a multicausation model that helps to see what happens. Some of the factors that were listed in the model are, air pollution, economics, environment, health care system, water quality, and the persons own behavioral choices, like smoking or not smoking or exercising regularly. When it comes to actually preventing these diseases there are three different levels, primary, secondary, and tertiary.
As a group we decided that this chapter really helped with understanding how the disesases are broken down and put into different catagories. Before reading the chapter we didnt really realize what epidemiology was and how many different parts there were to it. It was interesting and it's good to know about so that we can figure out ways to prevent these things happening. All the carts and diagrams also helped with understanding the overwhelming parts of the chapter.
It is important to be knowledgeable when it comes to communicable disease. And all we can really do is be aware. You can never be certain when a communicable disease or even the common cold will come up. But with knowledge and certain precautions that is the best anyone can do. The purpose of primary prevention is to educate and develop programs to promote health education. And with a secondary prevention, we can see an early diagnosis and start a treatment. Chapter 4 in this book was a great learning tool to help understand the steps of what to take when caring and treating communicable disease.
