乙型肝炎是由乙肝病毒(HBV)引起的、以肝脏炎性病变为主并可引起多器官损害的一种传染病。该病广泛流行于世界各国,主要危害儿童及青壮年,少数患者可转化为肝硬化或肝癌。因此,它已成为严重威胁人类健康的世界性疾病,也是我国当前流行最为广泛、危害性最严重的一种传染性疾病。为进一步加强对HBV感染的预防和控制,2007年湖北省巴东县疾病预防控制中心对城区4584名中小学生进行了HBsAg、HBsAb的筛查,对HBsAg阳性者作两对半检测,HBsAb阴性者进行乙肝疫苗预防接种。 相似文献

Falls are responsible for a substantial injury burden in the global workplace. Restaurant environments are particularly challenged by slips, trips, and falls. This study explored those factors that could influence workers' self-reports of slipperiness in U.S. fast-food restaurants. One hundred and twenty-six workers employed in 10 fast-food restaurants in the northeastern United States participated in the study representing a study-wide response rate of 87.5%. Participants' ratings of floor slipperiness and occupational slip history within the past 4 weeks were collected through written questionnaire. Additional factors collected by questionnaire included age, gender, shift length, and shoe type. Shoe condition (wear) and shoe contamination were visually assessed by the investigators. Floor friction was also measured. Lower restaurant mean coefficient of friction and the presence of contamination on workers' shoe soles were environmental factors significantly associated with workers reporting more slippery conditions. A recent workplace history of slipping with or without a subsequent fall was also significantly associated with workers reporting more slippery conditions. Workers over the age of 45 reported conditions to be significantly less slippery than younger workers. The results suggest that worker ratings of slipperiness are influenced not only by the actual level of friction but also by the other individual and environmental factors noted above. Recommendations for future studies would include a longitudinal design to better capture the temporal sequence between these variables. More field research is needed to better understand the association between workplace conditions, worker perception of slipperiness, and slipping at work. 相似文献

We report a case of ocular vaccinia infection in an unvaccinated laboratory worker. The patient was infected by a unique strain used in an experiment performed partly outside a biosafety cabinet. Vaccination should continue to be recommended, but laboratories with unvaccinated workers should also implement more stringent biosafety practices. 相似文献

Approximately 173 subjects employed as waiters, waitresses, or bartenders in the Knoxville, TN, Standard Metropolitan Statistical Area collected a sample of air from their breathing zone while at their workplace for one shift. In addition, area samples were placed near the work spaces of many of the subjects. Collected samples were analyzed for respirable suspended particulate matter (RSPM), ultraviolet-absorbing and fluorescing particulate matter, solanesol, 3-ethenyl pyridine (3-EP), and nicotine. Saliva samples were collected from the subjects prior to and within 24 h following their work shift, to confirm their non-smoking status. The range of concentrations of environmental tobacco smoke (ETS) constituents encountered was considerable, e.g., for nicotine, from undetectable to more than 100 microg/m3. However, the highest RSP levels observed were considerably lower than OSHA workplace standards. Distributions of ETS concentrations suggest that there are two "ETS exposure" types of bartenders: those that work in single room bars and those that work in larger, multiroom restaurant/bars. Personal exposure to ETS of the former group was ca. 10x greater than those of the latter group, who were exposed to ETS levels more comparable to those encountered by wait staff. Exposure (concentration x duration) differences between wait staff and workers in other types of unrestricted smoking environments reported in other studies suggest that exposures in the restaurant environment may be more difficult to assess than originally considered. Salivary cotinine levels indicated that for those subjects living in smoking homes, ETS exposures outside the workplace are at least as important as those in the workplace. 相似文献

A laboratory-confirmed case of hepatitis A was reported to Tri-County Health Department (TCHD) in Colorado, and the infected person was subsequently determined to have been a food worker at a local restaurant during the period of infectiousness. After conducting a public health risk assessment, TCHD decided to offer immune globulin (IG) to potentially exposed restaurant patrons. A two-day clinic in Adams County, Colorado, administered IG to 693 individuals. Planning, implementation, and evaluation of this clinic used a total of 900 staff hours and had a financial cost of dollar48,300. No additional restaurant employees became ill, and no secondary cases of hepatitis A were reported within the community. The mass-prophylaxis clinic was an important public health measure taken to prevent the potential spread of illness. The experience also provided relevant hands-on emergency-preparedness training that can be applied in other settings. 相似文献

The aim of the study presented in this paper is to estimate the economic cost of health risk exposure of the restaurant users in Dhaka city. In a large-scale survey, 400 restaurant users in Dhaka city belonging to lower-middle to high income group were asked for their preferences for a hypothetical ‘Food Safety Inspection Programme’ using closed ended dichotomous choice contingent valuation questions. The study reveals an average estimated willingness to pay of Tk31 (US$ 0.5) which is 13% of the average restaurant bill per visit per person. Aggregating the overall willingness to pay estimate across the whole population, a reduction in restaurant food-related health risk results in a total economic benefit of Tk2,250 million (US$33million) per year. The study, furthermore, reveals that the respondent' willingness to pay for the Inspection Programme varies with the degree of health risk exposure, respondent' income level, frequency of restaurant visits, the disutility from health risks and the levels of self-protection. Two different health risk indicators, subjective (respondent perceived probability of becoming ill after eating in a restaurant) and objective (experience of negative health incidences from low quality restaurant food), have been used to test the consistency of influence of health risk exposure on stated willingness to pay. Better model fit has been observed with the objective health risk exposure. The results from the statistical models indicate that the offered bid amounts (additional amount of money that the restaurant users need to pay in order to finance the Inspection Programme) affects willingness to pay negatively. We find income, frequency of restaurant visits and health consciousness influencing willingness to pay for the Inspection Programme positively. Finally, our results confirm the hypothesis that willingness to pay for health risk reduction varies positively with the levels of risk exposure independent of the type of indicators (subjective or objective) we use to measure health risk. 相似文献
