Disease , any harmful deviation from the normal structural or functional state of an organism, generally associated with certain signs and symptoms and differing in nature from physical injury. A diseased organism commonly exhibits signs or symptoms indicative of its abnormal state. Thus, the normal condition of an organism must be understood in order to recognize the hallmarks of disease.

Lesson 1: Introduction to Epidemiology

Bettina F. Despite a growing body of research into children's concepts of illness, many basic questions still remain. This study aims to describe 8- to year olds' lay beliefs of health, illness, health promotion and disease prevention. Children responded to open-ended questions about health and illness by drawing and writing their responses. Consistent with previous findings, the children of this sample have considerable knowledge about health, illness and disease risks.

The Concepts of Health and Disease

In digital society, knowledge is well distributed virtually and online. A substantial fraction of knowledge landscapes is also located in the digital environment. Both health and knowledge need to be understood today as a part of the digital society. It is important to estimate the impact that digital society has on knowledge landscapes and on health. Hence, this article deals with the concepts of health in relation to the present digital environment. How knowledge relevant to health and well-being is distributed in the digital society, and how the search for this knowledge, ie, navigating knowledge landscapes, influences everyday life and health needs to be clarified.

Disease , any harmful deviation from the normal structural or functional state of an organism, generally associated with certain signs and symptoms and differing in nature from physical injury. A diseased organism commonly exhibits signs or symptoms indicative of its abnormal state. Thus, the normal condition of an organism must be understood in order to recognize the hallmarks of disease. Nevertheless, a sharp demarcation between disease and health is not always apparent. The study of disease is called pathology. It involves the determination of the cause etiology of the disease, the understanding of the mechanisms of its development pathogenesis , the structural changes associated with the disease process morphological changes , and the functional consequences of those changes.

Evaluation and Explanation in the Biomedical Sciences pp Cite as. Health and disease are cardinal concepts of the biomedical sciences and technologies. Though the models of health and disease may vary, these concepts play a defining role, indicating what should and what should not be the objects of medical concern. The concepts are ambiguous, operating both as explanatory and evaluatory notions. They describe states of affairs, factual conditions, while at the same time judging them to be good or bad. Health and disease are normative as well as descriptive.


Other philosophers claim that the concept of health, together with the other medical concepts, is essentially value-laden. To establish that a person is healthy does.


Section 3: Concepts of health and wellbeing

Natural history of disease refers to the progression of a disease process in an individual over time, in the absence of treatment. It is now recognized that it may take 10 years or more for AIDS to develop after seroconversion. Image Description. Source: Centers for Disease Control and Prevention. Principles of epidemiology, 2nd ed.

A critical premise of epidemiology is that disease and other health events do not occur randomly in a population, but are more likely to occur in some members of the population than others because of risk factors that may not be distributed randomly in the population. As noted earlier, one important use of epidemiology is to identify the factors that place some members at greater risk than others. A number of models of disease causation have been proposed.

 А Фонд электронных границ будет праздновать победу, - побледнела Сьюзан. - Фонд понятия не имеет о том, чем мы тут занимаемся, - презрительно бросил Стратмор.  - Если бы они знали, сколько террористических нападений мы предотвратили благодаря тому, что можем взламывать шифры, они запели бы по-другому.

Двухцветный громко рассмеялся. - В такой одежде ты тут ничего не добьешься. Беккер нахмурился. - Я вовсе не хочу с ней переспать. Мне нужно с ней поговорить.

Джабба нередко прибегал к ВР, что в компьютерных кругах означало виртуальная реальность, но в АНБ это сокращение имело несколько иной смысл - визуальная репрезентация. В мире технических служащих и политиков, имеющих чрезвычайно разные уровни понимания, визуальная репрезентация нередко была единственным способом что-либо доказать: взмывающая вверх кривая производит куда более сильное впечатление, чем целые тома рассуждений. Джабба понимал, что ВР текущего кризиса со всей наглядностью объяснит то, что он хотел сказать. - ВР! - крикнула Соши, усаживаясь за компьютер в задней части комнаты.

 Он называл ее… - Речь его стала невнятной и едва слышной. Медсестра была уже совсем близко и что-то кричала Беккеру по-испански, но он ничего не слышал.

Фонтейн посмотрел на вспышки огней в куполе шифровалки. Глаза его расширились. Это явно не было составной частью плана. - У них там прямо-таки дискотека! - пролопотал Бринкерхофф. Фонтейн смотрел в окно, пытаясь понять, что происходит.

 И что. Хейл понимал: то, что он сейчас скажет, либо принесет ему свободу, либо станет его смертным приговором. Он набрал в легкие воздуха. - Вы хотите приделать к Цифровой крепости черный ход. Его слова встретило гробовое молчание.

 Сью… зан, - заикаясь, начал.  - Я… я не понимаю. - Я не могу, - повторила.  - Я не могу выйти за тебя замуж.

Через минуту его усилия увенчались успехом, а телефон все звонил и звонил. Христа ради, Мидж. Ну хватит .

Design/methodology/approach Definitions of the terms disease, illness and health are discussed against health concepts as a means of assessing the most.
