Sentinel mouse seroconversion to infectious agents is critical for laboratory animal facility disease monitoring. We report spontaneous emergence of non-sex-linked agammaglobulinemia with B-cell deficiency and cutaneous Staphylococcus aureus granulomatosis (botryomycosis) in a cohort of related Swiss Webster sentinel mice. Our experience reinforces the importance of immunocompetency validation ...
In June 1999, the dioxin crisis, caused by dioxin-contaminated feed components, exploded in Belgium, resulting in withdrawal of chicken and eggs from the market. Through the sentinel surveillance system, a decrease in Campylobacter infections during June 1999 was noticed. A model was generated with the reports from preceding years (1994 to 1998), and a prediction of the number of infections in ...
Somalia has suffered a massive internal population displacement and exodus that began in 1988 and is still ongoing during the prolonged and intermittent civil war. This review looks at the burden of HIV infection in Somali and the impact of civil war on its epidemiology. Serosurveys have indicated that HIV was not present in Somalia before the civil war and to date Somalia has had an HIV preval...
BACKGROUND Population-based sample surveys and sentinel surveillance methods are commonly used as substitutes for more widespread health and demographic monitoring and intervention studies in resource-poor settings. Such methods have been criticised as only being worthwhile if the results can be extrapolated to the surrounding 100-fold population. With an emphasis on measuring mortality, this s...
BACKGROUND Violence and rape are believed to fuel the HIV epidemic in countries affected by conflict. We compared HIV prevalence in populations directly affected by conflict with that in those not directly affected and in refugees versus the nearest surrounding host communities in sub-Saharan African countries. METHODS Seven countries affected by conflict (Democratic Republic of Congo, southe...
BACKGROUND So far, most pandemic influenza reports were based on case studies focusing on severe disease. For public health policy, it is essential to consider the overall impact of the pandemic, including mild diseases. OBJECTIVES The aim of our study is to gain insight into the epidemiology of 2009 pandemic influenza in the community and to estimate the relative impact of pandemic compared ...
OBJECTIVE Many countries are implementing measles elimination strategies. In Australia, the State of Victoria has conducted enhanced measles surveillance since 1997 using case interviews and home-based specimen collection for laboratory confirmation. We attempted to identify features of notified cases that would better target surveillance resources. METHODS We retrospectively classified notif...
Monitoring the Transmission of Schistosoma japonicum in Potential Risk Regions of China, 2008 – 2012
Schistosomiasis japonica, caused by Schistosoma japonicum infection, remains a major public health concern in China, and the geographical distribution of this neglected tropical disease is limited to regions where Oncomelania hupensis, the intermediate host of the causative parasite, is detected. The purpose of this study was to monitor the transmission of S. japonicum in potential risk regions...
the article by Watts and Kelly is timely in highlighting significant deficiencies in the surveillance of influenza in Australia. Watts and Kelly conducted a telephone survey of sentinel practice schemes in August 2001 and found that sentinel influenza surveillance schemes vary in their definition of influenza-like illness (ILI) and in their access to laboratory support. The impact of this is il...
Early detection of new or novel variants of nosocomial pathogens is a public health priority. We show that, for healthcare-associated infections that spread between hospitals as a result of patient movements, it is possible to design an effective surveillance system based on a relatively small number of sentinel hospitals. We apply recently developed mathematical models to patient admission dat...
