Choose two unrelated disease mechanisms and discuss all stages of prevention methods for each one.
A disease is the alteration of a normal state of an organism which impairs or in a similar way interrupts the usual activities of the vital functions. It can be seen by means of signs and symptoms and each and every disease carries distinguished observations. Since a disease is associated with signs and symptoms, it can be interpreted to be a medical condition. It can also be acquired by environmental factors like for example infectious diseases. Apart from the physical factors which may affect an individual during a disease, the latter may also be affected mentally and emotionally like for example by showing deviant behaviour which may later on affect not only the affected individual but also other people surrounding him/her.
There exist three different types of disease. ‘Localised diseases’ affect just one part of the body. ...view middle of the document...
Pathogens which consist of micro-organisms causing this disease include a whole spectrum of bacteria, fungi and viruses. These organisms can be transmitted from lack of hygiene, hand to mouth after contact with infectious material, insect bites, sexual transmission, so on and so forth.
Only some diseases such as influenza are contagious and commonly believed to be infectious. The micro-organisms that cause these diseases are known as pathogens and include varieties of bacteria, viruses, protozoa and fungi. Infectious diseases can be transmitted, e.g. by hand-to-mouth contact with infectious material on surfaces, by bites ofinsects or other carriers of the disease, and from contaminated water or food (often via faecal contamination), etc. In addition, there are sexually transmitted diseases. In some cases, micro-organisms that are not readily spread from person to person play a role, while other diseases can be prevented or ameliorated with appropriate nutrition or other lifestyle changes.
Some diseases, such as most (but not all) forms of cancer, heart disease and mental disorders, are non-infectious diseases. Many non-infectious diseases have a partly or completely genetic basis (see genetic disorder) and may thus be transmitted from one generation to another.
Social determinants of health are the social conditions in which people live which determine their health. Illnesses are generally related to social, economic, political, andenvironmental circumstances. Social determinants of health have been recognized by several health organizations such as the Public Health Agency of Canada and the World Health Organization to greatly influence collective and personal well-being. The World Health Organization's Social Determinants Council also recognizes Social determinants of health in poverty.
When the cause of a disease is poorly understood, societies tend to mythologize the disease or use it as a metaphor or symbol of whatever that culture considers to be evil. For example, until the bacterial cause of tuberculosis was discovered in 1882, experts variously ascribed the disease to heredity, a sedentary lifestyle, depressed mood, and overindulgence in sex, rich food, or alcohol—all the social ills of the time.
