The research has created the first detailed and up-to-date map of dengue distribution worldwide, enabling researchers to estimate the total numbers of people affected by the virus globally, regionally and nationally. The findings will help to guide efforts in vaccine, drug andvector control（传病媒介控制） strategies.   The study was led by Professor Simon Hay, a Wellcome Trust Senior Research Fellow at the University of Oxford, as part of the International Research Consortium on Dengue Risk Assessment, Management and Surveillance.   Dengue, also known as 'breakbone fever', is a viral infection that is transmitted between humans by mosquitoes. In some people, it causes life-threatening illness.   There are currently no licensed vaccines or specific treatments for dengue, and substantial efforts to control the mosquitoes that transmit the disease have not stopped its rapid emergence and global spread. Until now, little was known about the current distribution of the risk of dengue virus infection and its public health burden around the world.   Dr Samir Bhatt, who led the modelling for the study, says: "Our aim was to take all of the evidence that is currently available on the distribution of dengue worldwide and combine it with the latest in mapping and mathematical modelling to produce the most refined risk maps and burden estimates. We then hope to use this knowledge to help predict the future burden of the disease."   The findings reveal that dengue is ubiquitous throughout the tropics, with local spatial variations in risk influenced strongly by rainfall, temperature and urbanisation. The team estimate that there are 390 million dengue infections across the globe each year, of which 96 million reach any level of clinical or subclinical severity. This is more than triple the WHO's most recent estimates of 50-100 million infections per year.   Professor Simon Hay explains: "We found that climate and population spread were important factors for predicting the current risk of dengue around the world. With globalisation and the constant march of urbanisation, we anticipate that there could be dramatic shifts in the distribution of the disease in the future: the virus may be introduced to areas that previously were not at risk, and those that are currently affected may experience increases in the number of infections.   "We hope that the research will initiate a wider discussion about the significant global impact of this disease." 登革热感染的全球负担是超过三倍的电流从世界卫生组织的估计，一个跨国研究发在“自然”杂志上。这项研究已经建立了第一个全球登革热分布的详细和最新的地图，使研究人员估计总数的受病毒感染的人，在全球，区域和国家。这一发现将有助于引导力度疫苗，药物和矢量控制（传病媒介控制）策略。   领导这项研究是由牛津大学威康信托基金会高级研究员，教授西蒙干草，作为国际研究协会登革热风险评估，管理和监控的一部分。   登革热，也被称为“热病发烧”，是人类之间由蚊子传播的一种病毒性传染病。在一些人看来，它会导致危及生命的疾病。   目前有登革热，没有批准上市的疫苗或具体的治疗和控制蚊子传播疾病一直没有停止过它的迅速崛起和全球蔓延的重大努力。到现在为止，很少有人知道有关登革病毒感染的风险及其对公众健康负担在世界各地的电流分布。   萨米尔·哈特博士，谁领导为研究对象的建模，说：“我们的目的是要考虑所有的证据，是目前可在全球登革热的分布，并结合最新的测绘和数学建模，制作最精风险地图和负担估计，然后我们希望利用这方面的知识，以帮助预测未来的疾病负担。“   调查结果表明，登革热是无处不在整个热带地区，具有强烈影响降雨，气温和城市化的局部空间变化的风险。该小组估计，有3.9亿在全球范围内，每年的登革热感染病例，其中96万达到任何水平的临床或亚临床严重性。这是超过三倍世界卫生组织的最新估计为每年50-100万感染。   西蒙·海伊教授解释说：“我们发现，气候和人口预测目前的风险的登革热在世界各地蔓延的重要因素，随着全球化的发展和城市化进程的不断行军，我们预计，有可能是戏剧性的变化，疾病的分布在未来的病毒可能会被引入到以前是没有风险的领域，以及那些目前受感染人数可能增加。   “我们希望这项研究将引发重大的全球影响本病的一个更广泛的讨论。” “成千上万人疯狂下载。。。。。。 更多价值连城的绝密英语学习资料， 洛基内部秘密英语，技巧，策略 请在 网上 申请报名” 洛基国际英语 竭诚为您服务
