Diseases resulting from zoonotic transmission of parasites are common. Humans become infected through food, water, soil and close contact with animals. Most parasitic zoonoses are neglected diseases despite causing a considerable global burden of ill health in humans and having a substantial financial burden on livestock industries. This review aims to bring together the current data available on global burden estimates of parasitic zoonoses and indicate any changes in the trends of these diseases. There is a clear need of such information as interventions to control zoonoses are often in their animal hosts. The costs of such interventions together with animal health issues will drive the cost effectiveness of intervention strategies. What is apparent is that collectively, parasitic zoonoses probably have a similar human disease burden to any one of the big three human infectious diseases: malaria, tuberculosis or HIV in addition to animal health burden. Although the global burden for most parasitic zoonoses is not yet known, the major contributors to the global burden of parasitic zoonoses are toxoplasmosis, food borne trematode infections, cysticercosis, echinococcosis, leishmaniosis and zoonotic schistosomosis. In addition, diarrhoea resulting from zoonotic protozoa may have a significant impact. 相似文献

After four-decade significant economic growth and development, China sets a series of goals aiming at sustainable medium to high speed economic growth,reasonable equity, and better market oriented economy. In this pursue, agriculture will take a crucial role. Under the Health China 2030, National Nutrition Plan (2017-2030) and Rural Vitalization Strategy, more attention has been paid on nutrition both in policy and research field, meanwhile the linkage between agriculture and nutrition is enhancing, but the integration of Agriculture-Food Security-Nutrition system is not yet completed. During the economic transformation, agriculture and food industry will play a key role, especially when considering the nutrition and health status will impact the national physical fitness and therefore influence the economic transformation approach. It may also impact whether China can move out of the Middle Income Trap to some extent. In the new development era, China needs a new food security development strategy to improve the national nutrition status and sets of policies to strengthen the integration of agriculture and nutrition. This paper reviewed the major challenges about China’s food security and put forward a new vision based on international experiences, which aimed at providing recommendations for designing China’s food security strategy. The key food security challenges include natural and environmental pressure, such as insufficiency and degradation of land resources, shortage and pollution of water resources, climate change and extreme disaster, fiscal pressure caused by increasing agriculture subsidy, Triple Burden of malnutrition, food safety issues and food loss and waste. It requires institutional and technical innovations for the transformation of agriculture development which means that more value added, nutritious and healthy food should be produced, the productivity and efficiency of water, land and energy should be improved, and environmentally friendly social inclusive development should be considered. All of those call for a transformation of China’s food security strategy. This paper put forwards a new vision for China’s food security: China should set nutrition-oriented food security strategy with nutrition indicators as key targeted goals, aim to eliminate hunger and undernutrition by 2025 while effectively reducing overweight/ obesity and food safety risks. Therefore policy innovations are recommended including: Improve nutrition governance, Market motivated and nutrition oriented agriculture support system, Promote Nutrition-based Food Production, Establish efficient, safe, and inclusive food value chains, Policy innovation for sustainable nutritious diet and nutrition education, and Evidence based research to support policy making. 相似文献

日本的受益者负担制度与中国的行政收费制度具有相似之处,研究其对于规范中国的行政收费具有借鉴意义。受益者负担作为日本地方财政收入的方式之一,是指对于特定公共服务的特别受益者,在其受益的范围内,以分担金、负担金、使用费、手续费等形式使其承担该经费的一部分或全部的制度。其理论基础在于"特别受益"应当由"特别负担"来补偿的理论,因此,界定受益者负担的范围就是要界定被征收者与特定行政支出之间是否具有这种"特别受益"关系,而界定"特别受益"关系应当以受益范围的"特别性"与受益程度的"显著性"为标准。 相似文献
