Uses of Epidemiology
Epidemiology, as a health science, is a study of the prevalence of a disease and its percentage rate of occurrence in the separate classes of the population and the reasons as to this. This scientific study is useful in the planning and evaluation of the strategy to be employed to prevent spreading the illness and managing the current patients. The term ‘population at risk’ is used to refer to the part of the general population that may be exposed to the incidence of a health- related event, such as the total population that are under the possibility of contracting HIV. In this case, the population at risk will refer to the children who are placed at a disadvantage in terms of contraction of Whooping Cough (Tan, Trindade & Skowronski, 2005).. The children who have not received immunization are placed at the risk of contracting the disease- since they are vulnerable. They thus will be classified as the population at risk, and its percentage in assumption that Fallsburg Elementary School is a closed environment or an independent population.
In taking statistics of persons at risk, it is assumed that the interaction between the total population is even, and thus it can be said that the at- risk persons may contract the disease, although in reality, a small part of these persons actually do. In this environment, the children who did not receive immunization have not developed any defense against the disease, and in the case that they come into contact with the causative bacteria. These children are thus considered to be prone to disease at all time. There is a percentage which had received immunization. This part of the elementary student’s population considered to be ‘not at risk’ (Gregory, 2006). Thus the statistics would state that from the calculation below, it was determined that 41.67% of the elementary s...
