Abstract

Loss estimates are needed to develop rational economical control measures and to impress upon administrators and donors for efficient disease management. Losses can be actual and potential, incidental and regular, transitional and structural, primary and secondary. Various measuring principles and development of methods to estimate losses are discussed.
