BACKGROUND Outbreak detection algorithms play an important role in effective automated surveillance. Although many algorithms have been designed to improve the performance of outbreak detection, few published studies have examined how epidemic features of infectious disease impact on the detection performance of algorithms. This study compared the performance of three outbreak detection algorit...

To the Editor: A serious outbreak of chikungunya disease recently occurred on Reunion Island (popula-cases were reported in this French territory in the Indian Ocean. Most cases occurred after mid-December 2005, with a maximum of 45,000 cases during the week of January 29 to February 4, 2006 (2). Surveillance figures were confirmed by a serosur-vey that found a prevalence of 18% of recent infec...

In this paper, we proposed the historical data of dengue disease in Thailand. The reported case and death due to dengue disease are presented by total number, region, month, age, and occupation. The mathematical model is the key to analyze dengue disease which can investigate the reproductive number in order to control the outbreak. At the current, the best way to control the outbreak is contro...

conclusions health disobedience and neglect of local residents were the causes of water pollution that was controlled with preventional measures, with performing daily chlorination of brick kilns drinking water and diarrheal disease treatment of the patients. results a total of 120 workers were studied (60 cases and 60 controls) who were the same from age and sex point of view. clinical signs o...

an outbreak of a lethal disease was reported in 4–6-month-old holstein calves in a feedlot around tehran. the signs of central nervous system and gastrointestinal system (gi) involvement were observed in the diseased animals. necropsy samples of gi, liver, kidney, spleen and lung from 3 died animals were prepared for histopathological examination. blood and formalin-fixed ear notch samples of 6...

Cellular Automata (CAs) are often used to simulate complex systems. One such application of a CA is to simulate the spread of disease through a susceptible population. This paper describes EpiViz, a CA-based epidemic simulator which uses a variety of input parameters, such as probability of infection, infectious period, vaccination rate, mode of infection, and probability of recovery to influen...

Recent infectious disease epidemics illustrate how health systems failures anywhere can create disease vulnerabilities everywhere. We must therefore prioritize investments in health care infrastructure in outbreak-prone regions of the world. We describe how "rooted" research collaborations can establish capacity for pathogen surveillance and facilitate rapid outbreak responses.
