Between April 2012 and June 2014, 820 laboratory‐confirmed cases of the Middle East respiratory syndrome coronavirus (MERS‐CoV) have been reported in the Arabian Peninsula, Europe, North Africa, Southeast Asia, the Middle East, and the United States. The observed epidemiology is different to SARS, which showed a classic epidemic curve and was over in eight months. The much longer persistence of MERS‐CoV in the population, with a lower reproductive number, some evidence of human‐to‐human transmission but an otherwise sporadic pattern, is difficult to explain. Using available epidemiological data, we implemented mathematical models to explore the transmission dynamics of MERS‐CoV in the context of mass gatherings such as the Hajj pilgrimage, and found a discrepancy between the observed and expected epidemiology. The fact that no epidemic occurred in returning Hajj pilgrims in either 2012 or 2013 contradicts the long persistence of the virus in human populations. The explanations for this discrepancy include an ongoing, repeated nonhuman/sporadic source, a large proportion of undetected or unreported human‐to‐human cases, or a combination of the two. Furthermore, MERS‐CoV is occurring in a region that is a major global transport hub and hosts significant mass gatherings, making it imperative to understand the source and means of the yet unexplained and puzzling ongoing persistence of the virus in the human population.  相似文献

Determination of the cognitive and behavioural demands of work is an important part of holistic workplace intervention. Attention to these factors is especially important when developing return-to-work programs for persons with reduced cognitive, behavioural or psycho-emotional capacity, and when designing risk management programs in organizations. Occupational therapists have the background knowledge and skills to assess these components of work, but often lack valid and reliable measurement tools. This paper reports on three field studies that assessed the reliability and validity of ratings made by novice users of the City of Toronto Job Demands Analysis, which includes a measure of cognitive and behavioural work demands. Numerous challenges to accuracy and reliability that are common to empirical measurement were disclosed, including the necessity for clear and strong definitions, and the importance of thorough rater training. Implications for therapist training and mentorship are discussed.  相似文献

Residential Treatment Centres (RTCs) provide 24-hour care and mental health services to young people, many of whom are referred from county departments that oversee services to young people involved with child welfare services, mental health services and corrections. While RTCs are required to provide mental health services to young people, the regulations governing these programmes have few specific requirements about the process, content or duration of treatment. Therefore, many questions have arisen about what a typical RTC day looks like and whether it differs among providers or differs based on the severity or type of the young person's mental-health related behaviours and symptoms. This study conducted interviews with RTC providers in the State of Colorado on this topic. Most RTC services were relatively uniform across case types within each RTC. It appears that with a few exceptions, a similar set of services is provided to all young people, regardless of their problems.  相似文献
