We evaluated a novel strategy to improve the performance of outbreak detection algorithms, namely setting the alerting threshold separately in each region according to the disease incidence in that region. By using data on hand, foot and mouth disease in Shandong province, China, we evaluated the impact of disease incidence on the performance of outbreak detection algorithms (EARS-C1, C2 and C3...
Increased concern about bioterrorism and emerging diseases is driving the development of systems for early epidemic detection. These systems have different requirements than traditional public health monitoring systems. They typically deal with larger and more diverse data sets and must use a large variety of analysis techniques to perform real-time tracking of multiple syndromes. Operationally...
There has recently been a surge of research efforts aimed at very early detection of disease outbreaks. An important strategy for improving the timeliness of outbreak detection is to identify signals that occur early in the epidemic process. We have developed a novel algorithm to identify aggregates of "similar" over-the-counter products that have strong association with a given disease. This p...
In August 2013, Xishuangbanna, Yunnan Province, China, had its first dengue outbreak. Dengue virus (DENV) RNA detection in sera or viral isolates revealed that all 222 autochthonous patients detected and three Chinese travelers from Laos (imported cases) were positive for DENV-3 serotype, while DENV-1 and DENV-4 were detected in travelers from Myanmar and Thailand during the outbreak. For 33 su...
Listeria monocytogenes, a bacterial foodborne pathogen, can cause meningitis, bacteremia, and complications during pregnancy. This report summarizes listeriosis outbreaks reported to the Foodborne Disease Outbreak Surveillance System of the Centers for Disease Control and Prevention during 1998-2008. The study period includes the advent of PulseNet (a national molecular subtyping network for ou...
ebola virus (ebov) is an enveloped virus including a negative single strand genome in its virion with cylindrical/tubular morphology. ebov is the causative agent of ebola virus disease (evd), which is also involved in the outbreak observed in central africa since 1976. evd is a complex zoonotic viral disease which is highly virulent in human. the transmission of ebola infection is not usually h...
plague is an infectious disease transmitted from rodents to humans. this disease is considered an endemic disease in western iran. the last officially reported case of human plague in iran was in 1965. in the last few decades, human plague has been reported in iran’ neighboring countries. also, according to some recent evidence witnessing infected rodents in western iran, it is probable to have...
background: the postoperative shivering is one of the common complications of anesthesia after surgery and in the recovery room, which can cause the increased systemic blood pressure, oxygen consumption, heart rate and the cardiac arrhythmias among patients. due to the variety of drugs used in general anesthesia, and necessity of choosing the effective intravenous and the inhaled drugs to reduc...
We conducted a retrospective study to ascertain the potential of free-text chief complaints collected in pediatric emergency departments to serve as surveillance data for early detection of outbreaks. detection from such data and both suffered from either methodological limitations or very small sample size. 4,5 The present study attempts to measure performance characteristics of a biosurveilla...
BACKGROUND In April 2012, the Jordan Ministry of Health investigated an outbreak of lower respiratory illnesses at a hospital in Jordan; 2 fatal cases were retrospectively confirmed by real-time reverse transcription polymerase chain reaction (rRT-PCR) to be the first detected cases of Middle East respiratory syndrome (MERS-CoV). METHODS Epidemiologic and clinical characteristics of selected ...
