Clostridioides difficile remains an important public health threat, globally. Since the emergence of the hypervirulent strain, ribotype 027, new strains have been reported to cause C. difficile infection (CDI) with poor health outcomes, including ribotypes 014/020, 017, 056, 106, and 078/126. These strains differ in their geographic distribution, genetic makeup, virulence factors, and antimicrobial susceptibility profiles, which can affect their ability to cause disease and respond to treatment. As such, understanding C. difficile epidemiology is increasingly important to allow for effective prevention measures. Despite the heightened epidemiological surveillance of C. difficile over the past two decades, it remains challenging to accurately estimate the burden and international epidemiological trends given the lack of concerted global effort for surveillance, especially in low- and middle-income countries. This review summarizes the changing epidemiology of C. difficile based on available data within the last decade, highlights the pertinent ribotypes from a global perspective, and discusses evolving treatments for CDI.
Background: Taiwan suffered a serious Enterovirus-71 epidemic in 1998 and 78 children were dead from the outbreak. Several infectious disease surveillance systems were designed to detect virus situation in the community. However most of the surveillance system were passive surveillance and relied on physician reporting. Hence that an emergency department based syndromic surveillance system (ED-SSS) was developed and adopted in Taipei city after 2003 SARS outbreak. We aimed to use the syndromic surveillance to identified enterovirus-like illness (EVI) patient and triggered for the specimen collection and virus detection.Methods: There are 5 hospital enrolled in the ED-SSS in Taipei city. The EVI case number is daily and automatically generated by the system. We use historical control limit and CUSUM method to be abnormal detection algorithm. Only if the system indicated abnormal signal, the ED staffs collect specimens from EVI patient. All samples would be tested by RT-PCE and virus culture with influenza virus, enterovirus, adenovirus, etc. to identify the disease cause agent.Results: There were total 161,366 ED visits and 304 EVI cases were identified by the ED-SSS during Jan. 2007 to Oct. 2007. According to the historical control limit method, 29 EVI signals were triggered. We collected 169 samples from 5 hospitals to identify disease cause agents. The overall virus isolation rate is 15.4% (26/169). Six of 26 positive samples were enterovirus. The EV cases virus serotypes were CA16 (66.7%) and CA6 (33.3%). They were all under 7 year old children and the gender distribution is two males and four females respectively and distributed in different area of Taipei city.Conclusion: The syndromic surveillance system could provide public health department to initiate active surveillance with scientific evidence. Taipei city is the first metropolitan using such active surveillance to rapid response and capture virus activities in Asia. The integration of syndromic surveillance and other different surveillance systems is the most important future work. We also will to cooperate with other city to establish international cooperate surveillance to detect novel enteroviruses and other emerging infectious cause agents.
This article aims to provide a holistic and comprehensive summary on the political impacts as well as economic impacts of the Reunification of Germany in 1990 due to the fact that politics and economics are inter-linked.This article analyses political impacts through linking the reunification with other geopolitical changes in the world that took place afterwards, and discovered that the reunification did not effectively eliminate the division between Eastern and Western Germany and strengthened right-wing extremism in the East, yet contributed to the easing of global tensions, the dissolution of the Soviet Union and the integration of Europe. This article analyses economic impacts mainly through the comparison of various macroeconomic indicators, including annual GDP growth rate, unemployment rate, and inflation rate, of the German Democratic Republic(GDR) and the Federal Republic of Germany(FRG) before reunification and western and eastern Germany after reunification, and discovered that the reunification had in general negative domestic economic impacts, and that the economic disparity between eastern and western Germany has not been eliminated yet.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
