– Timeliness, to implement effective control measures; – Representation, to provide an accurate picture of the temporal trend of the disease; – Sensitivity, to allow identification of individual persons with disease to facilitate treatment; quarantine, or other appropriate control measures; and – Specificity, to exclude persons not having disease.

How does disease surveillance relate to epidemiology?

Evolving epidemiology of disease, the increasing prevalence of antimicrobial drug resistance, and the development of new vaccines and prophylactic treatments have each contributed to create the ongoing need for surveillance of international travelers.
