Population-based surveillance for unexplained death and critical illness possibly due to infectious causes (UNEX) was conducted in four U.S. Emerging Infections Program sites (population 7.7 million) from May 1, 1995, to December 31, 1998, to define the incidence, epidemiologic features, and etiology of this syndrome. A case was defined as death or critical(More)
During the pandemic (H1N1) 2009 outbreak, Minnesota, New Mexico, and Oregon used several surveillance methods to detect associated deaths. Surveillance using unexplained death and medical examiner data allowed for detection of 34 (18%) pandemic (H1N1) 2009-associated deaths that were not detected by hospital-based surveillance.
Electronic emergency department reporting provides the potential for enhancing local and state surveillance capabilities for a wide variety of syndromes and reportable conditions. The task of protecting data confidentiality and integrity while developing electronic data interchange between a hospital emergency department and a state public health department(More)
Specimens (brain, meninges, spinal cord, nerve) will be sent to Centers for Disease Control and Prevention (CDC) for testing by monoclonal antibody, hybridization, electron microscopy, or polymerase chain reaction (PCR). Before any testing, 250 µL (or other amount) from each specimen will be stored in a serobank. First-round tests will be performed on all(More)
Broad-range rDNA polymerase chain reaction (PCR) provides an alternative, cultivation-independent approach for identifying pathogens. In 1995, the Centers for Disease Control and Prevention initiated population-based surveillance for unexplained life-threatening infections (Unexplained Death and Critical Illness Project [UNEX]).
