As government institutions become more and more concerned with health problems ; the need for reliable prevalence and incidence data is increasing (Friis & Sellers, 2014) however; to estimate accurately the number of individuals having a given disease is not easy The number of subjects already diagnosed is useful to measure the impact of health services The epidemiologist also tries to detect new cases , so far diagnosed . In both situations the classical epidemiological approach using random population sampling is extreamly expensive alternative methods to estimate the number of subjects with a defined health problem corrective for deficiencies in assesstment have been proposed. Epidemiological Exposure Analysis include estimation of demographics and population characteristics just to name a particular method to determine prevalence or risk analysis in epidemiology that are useful in alternative more expensive methods of collecting data to estimate prevalence and or incidence rates . These are useful for example in determining par levels needs in for example antidotes to specific toxins . There are many uses in alternative data collection methods and we can certainly see there applicability in settings that may not have been thought of at first glance .
So what is antidote ? . An antidote is a medicine taken to counteract a toxin . What are par levels ? . Par levels is a system used in Inventory to estimate needs and other characteristics of said inventory . Applying alternate prevalence data and incidence are always the preferred epidemiological mathematical application in population health , how ever we can appreciate more complex epidemiological application to practice , and their usability.
