|The Centers for
Disease Control and Prevention (CDC) acts as a common agent for the States and territories
in the collection and reporting of nationally notifiable diseases. Reports of the
occurrences of nationally notifiable diseases are transmitted to CDC each week from the 50
States, 2 cities, and 5 territories through the National Electronic Telecommunications
System for Surveillance. Provisional data are published weekly in the Morbidity and Mortality
Weekly Report; final data are published each year in the annual Summary of Notifiable Diseases,
United States. The timeliness of the provisional weekly reports provides
information that CDC and State or local epidemiologists use to detect and more effectively
interrupt outbreaks. Also, reporting provides the timely information needed to measure and
demonstrate the impact of changed immunization laws or a new therapeutic modality. The
finalized annual data also provide information on reported disease incidence, which is
necessary for the study of epidemiologic trends and the development of disease prevention
policies. Different reportable diseases will be featured periodically on the Social Statistics Briefing Room.
