The Monitor and Prevention and Cure of Flu
There is a joke among flu researchers: "If you’ve seen one flu season, you’ve seen. . . one flu season." The translation, for those not up on epidemiological humor: the joke is humorous commentary on the unpredictable nature of the flu virus. Every year it looks different, and every strain follows its own pattern. This is not just a quirk that frustrates scientists—it’s the reason new strains like H1N1 are impossible to anticipate and fully prepare for.
" I know less about influenza today than I did 10 years ago," quips Dr. Michael Osterholm, director of the Minnesota Center of Excellence for Influenza Research and Surveillance and a former adviser to the U. S. Department of Health and Human Services. "Every stone we’ve turned over, we get more questions than we do answers."
The flu returns every season and the world periodically experiences catastrophic pandemics, but epidemiologists still do not understand why some strains evolve to infect people and others do not; they are not entirely sure about how the flu is transmitted; nor do they understand why some patients become fatally ill while others develop minimal symptoms. As a result, when a new strain shows up—like H1N1—they often have little information to fall back on, and the lessons of previous pandemics are only somewhat helpful. While epidemiologists are still putting together a complete picture of H1N1, for example, its most striking difference with the seasonal flu is that the elderly are not the most vulnerable population. And when H1N1 does cause serious illness, patients develop different complica-tions(that are more difficult to treat) than those with seasonal flu. "It’s very different death," says Osterholm.
The Centers for Disease Control currently maintains six different categories of flu-surveillance programs, but has rolled out new measures this year in order to monitor H1N1’s most worrying features. The backbone of its routine surveillance systems is not designed to count individual flu cases, but rather to get general indicators of how the flu is and which strains are in circulation. Uncertainty about the fast-moving H1N1 prompted the CDC to begin asking state health departments to report the number of hospitalizations and deaths caused by influenza, and it is still adjusting the methods for calculating the disease’s impact. Even the methods for counting the number of those who died of H1N1 is uncertain: on Tuesday, The New York Times reported that the CDC will revise its estimates of H1N1 deaths to 4,000 from 1,200. This revised figure is the result of a new calculation that encompasses fatal cases confirmed via lab tests to have been caused by H1N1, as well as hospital reports of deaths that "appear to have been brought on" by the flu.
What can we learn from Dr. Michael Osterholm’s words?
选项
A、The variability of flu virus.
B、He has quited the study of flu.
C、the degeneracy of flu study.
D、Every flu virus can be conquered.
答案
A
解析
推理判断题。根据题干关键词Dr.Michael Osterholm定位到第二段。本题考查欧斯特赫姆的自嘲。真实含义是,其对于流感的认识并未减少,而是从另一个侧面反映了流感的多变性,总有新的变种出现。由此可推知[A]含义与之相符,故为正确答案。[B]“他放弃了对流感的研究”和[C]“流感研究的退步”与原文不符,故排除;该段末句的含义是每战胜一种流感,就会有更多的问题出现,并未提及所有的流感都可被征服,故排除[D]。
