 Induction Periods and Latent Periods

Show Summary Details

Preview

For etiologic exposures of brief duration, such as eating food contaminated with the hepatitis A virus or being subjected to a single, intense dose of ionizing radiation, the induction period in a given sick person is the interval between receipt of the exposure and the first presence of the disease. The latent period is the time between the disease's first presence and its recognition. This chapter discusses induction periods and latent periods. The influence of the suspected induction/latent period on study design is considered. Exercises are provided at the end of the chapter.
