National Notifiable Disease Surveillance System

Several types of data are routinely collected related to infectious disease surveillance, including morbidity, mortality, and health indicator data (CDC, 1992). Each state has requirements for mandatory reporting by health care providers and facilities, including laboratories, of cases of notifiable infectious diseases. There is a national notifiable disease list as well, for which reporting is voluntary, with data compiled through the National Notifiable Disease Surveillance System (CDC, 2004d, 2006). 

Passive in a passive system, health care providers or institutions initiate case reports, which are compiled at the local level and subsequently at state and national levels (CDC, 1992). The National Notifiable Disease Surveillance System (NNDSS) in an example. An important point is that it is only after individual case reports are compiled that an outbreak may be apparent (Bres, 1986), so timely reporting is essential for effective control. 

A description of the National Notifiable Disease Surveillance System (NNDSS) is available at http //www.cdc.gov/epo/dphsi/nndsshis.htm.

The Centers for Disease Control and Prevention (CDC) oversees a large number of passive infectious disease surveillance systems. These systems are based on voluntary collaboration with state and local health departments, which in turn depend on physician-initiated reports of specific diseases or information from state health laboratories regarding bacterial or viral isolates. The best known system is the National Notifiable Disease Surveillance System, which the CDC describes as the backbone of collaborative reporting procedures involving clinicians, state, and local health departments, and the CDC. Clinicians, hospitals, and laboratories...
