ResumoAbstract This chapter discusses the acquisition of information for use in the public health arena, called surveillance. Public health surveillance is a basic tool of the field epidemiologist, providing the scientific and factual database essential to informed decision-making and to the conduct of public health prevention and control programs. Surveillance is based on morbidity, mortality, and risk factor data, often from multiple sources. Some data, such as vital statistics, are collected primarily for other uses; other data, such as behavioral risk factors, are collected specifically for the surveillance system.
