Hepatitis in Developing Countries: Still a Scourge
Journal Title: Journal of Medical Sciences - Year 2017, Vol 20, Issue 2
Abstract
Screening is defined as the application of a diagnostic test to an asymptomatic population in order to detect a disease at a stage when intervention may improve its outcome and natural history.1 In simpler terms, screening is a strategy that is used in a population to identify the likely presence of an as-yet-undiagnosed sickness in individuals without its signs or symptoms. By itself, screening tests are somewhat unusual in that they are performed on people who are apparently in good health. However, screening interventions are intended for early identification of disease in a population, that may enable earlier intervention and treatment. The idea is to reduce mortality and suffering from a disease through early detection and management. Whereas screening may lead to an earlier diagnosis, the testing may not necessarily prove beneficial to person being screened. Apart from the issues of over- and mis-diagnosis, and inappropriate use or overuse, screening may create a false sense of security. Though screening strategies are never designed to be diagnostic, how to deal with false positive and false negative results remains an issue.
