Descriptive Epidemiology




Descriptiveepidemiology establishes the factors and issues behind the existenceof a certain health condition, health events or health phenomenon. Byadopting the basis of a place, descriptive epidemiology explores theprevalence based on the population in all its characteristics such asage, race, country or special groups (Friis &amp Sellers, 2014).This way, descriptive epidemiology contributes to the identificationof the extent of a public health problem. Moreover, such descriptiveepidemiology enhances the understanding of the depth of a healthysituation after identifying the public health problem.

Throughthe use of descriptive epidemiology, the investigation of a healthsituation provides important data on the disease of a healthsituation. According to (Friis &amp Sellers, 2014), the dataexplored provides a basis of describing the health problem in alanguage that is understood and risky cases analyzed. This enhancesthe communication of the situation. For instance, the description ofthe data on the prevalence of a disease can be based on the place,the population affected and the people affected. Such data will helpin the understanding of the risky people, risky places and thecommunication of the situation to people.

Descriptiveepidemiology provides the changes in the prevalence of a healthproblem, such as an increase or decrease in the prevalence rate. Thishelps to evaluate the effectiveness of a public health program whichis measured by the reduction of the prevalence of the health problembeing handled (Friis &amp Sellers, 2014). Moreover, descriptiveepidemiology provides data on the historical prevalence of a healthproblem. This provision helps in the investigation of clues of thepossible causes of the disease. More importantly, descriptiveepidemiology allows investigation of the prevalence and examinationbased by place, by person and time. This makes descriptiveepidemiology an important step of the investigation of a healthproblem.
