The world health watchdogs are looking in the wrong places for the next dan

问题      The world health watchdogs are looking in the wrong places for the next dangerous epidemics, according to an analysis of global trends in emerging disease outbreaks over the past few decades.
     The study gives a fresh perspective on global disease by tracking the history, from 1940 to 2004, of the emergence and spread of 335 infectious diseases. The extensive work helps to quantify the effect of well-known risk factors, such as population density, on the probability of a disease taking hold in a given area.
     Although the data haven’t yet been used to map out specific future hotspots for disease, they do suggest that watchdog groups should invest more in monitoring regions such as tropical Africa, Latin America and Asia. These areas have the greatest threats of newly emerging epidemics, say the survey’s authors, but they have traditionally received the least surveillance.
     A globally coordinated strategy is required to spot and stop outbreaks before they can spread across the world, argues Kate Jones of the Institute of Zoology in London, one of the researchers behind the new report.
     "We need to think more broadly, with a global vision." she says, "Everyone will be affected by new disease outbreaks. We are all on the same planet--there’s nowhere to hide."
     Jones and her colleagues tracked the infectious diseases over a 64-year span. They included many diseases that have gone on to cause worldwide misery. The survey paints a picture in which new diseases arise as a result of dramatic increases in human population density, international trade and travel, and changes to agricultural practices.
     Such changes have caused a dramatic increase in the rate at which new diseases have emerged since the 1940s, the researchers say. During the 1980s alone, the worst decade in their date set, almost 100 new pathogens emerged.
     That is probably due to the ravages of the most notorious pathogen(病原体，致病菌) to appear in the 1980s--HIV--the researchers note.
     HIV, like 60% of the diseases studies by the researchers, is a zoonotic(动物传染病的) pathogen-it leapt from animals to humans. Of these zoonotic diseases, 72% came from wildlife as opposed to domesticated animals, the researchers found. Recent examples include Nipah virus in Malaysia, and the infamous SARS outbreak in Guangdong, China, which practically shut down international travel in Southeast Asia in 2002. [br] According to Kate Jones, what should be done to detect and stop the epidemics before they can spread across the world?
选项
答案 To develop a globally coordinated strategy．
解析 本题问的是伦敦动物学研究所的凯特通过研究认为，要在新的流行疾病扩散至全世界之前发现和阻止它，需要采取什么措施，；原文已经提到需要制定一项全球性的协调战略才能较早发现并有效阻止疾病的爆发，题干中detect是spot的问义转述，依据这一点可以找到本题的答案为To develop a globally coordinated strategy。
