某地发现数百名不明原因传染性肺炎病例(后被确诊为SARS),死亡2例,危重100例,患病者以医护人员居多。

新传染病发生的影响因素()

A.国际旅行和商业活动随国际贸易和旅游业而迅速发展

B.技术和工业因素

C.生态与环境变化

D.微生物的进化

E.公共卫生措施的失效

F.人口特征与行为因素影响

答案

参考答案:A, B, C, D, E, F

解析:

1.医疗卫生机构对突发公共卫生事件应采取的应急处理措施:①负责突发公共卫生事件的技术调查、确证、处置、控制和评价工作。②服从突发公共卫生事件应急处理指挥部的统一指挥,相互配合、协作、集中力量开展相关的科学研究工作。③对因突发公共卫生事件致病的人员提供医疗救护和现场救援,对就诊患者必须接诊或者送到指定的医疗机构。④采取卫生防护措施,防止交叉感染和污染。⑤对与传染病患者密切接触者采取医学观察措施。⑥收治传染病患者、疑似传染病患者,应当依法报告所在地的疾病预防控制机构。⑦接到报告的疾病预防控制机构应当立即对可能受到危害的人员进行调查,根据需要采取必要的控制措施。⑧对传染病做到早发现、早报告、早隔离、早治疗,以切断传播途径,防止扩散。

2.新发传染病的危害性:①疫情发生初期,临床医生不认识,不知应该采取何种治疗方案,所以病死率高居不下。②病因不确定,不知应该采取何种特异性的预防和控制措施。③政府得不到专业人员的明确意见,也无法及时作出决策。④大众得不到有效的宣传和教育,恐慌心理严重,容易造成社会的不稳定。⑤先进的交通工具、现代国际贸易和交流,可以迅速把传染病从一个国家或地区传向全球,造成世界大流行。⑥新发传染病具有不确定性,依靠目前的科技水平,不能预测何时何地会发生何种新发传染病,无法做好特异性的准备。

3.新传染病发生的影响因素:①微生物的变异:环境选择造成变异,变异的循序渐进和突变,分子生物学进展的双刃作用等。②生态及环境变化:气候变化,洪水,干旱,砍伐森林和(或)植树绿化,农业发展。水生态系统变化等。③人口特征与行为:社会条件,人口增长和移民,战争,贫困,城市的发展与衰退,性行为,静脉用药,饲养宠物等。④技术和工业:食物供应全球化,食品包装和加工的改变,输血,组织和器官移植,抗菌药的广泛使用,中央空调的发展使用等。⑤国际旅行和商业活动:人及货物的世界性交流,各种交通快捷发展,空中旅行等。⑥公共卫生措施的失效:媒介控制,饮水净化及消毒,专业技术落后等。4.以上各条均是新发传染病的应对措施。

Limit the use of private cars, improve public transport and encourage the use of bicycles to control traffic congestion(拥挤) during the 2008 Olympics, experts from foreign countries advised Beijing on Friday.

Professor Nigel Wilson, of the civil and environmental engineering department of Massachusetts Institute of Technology, said he was "supportive to the limiting of private cars during the Olympic Games", saying that in foreign countries, the method is also adopted during big events, but he was unsure about the approach.

The government planned to keep an average of more than one million cars off the roads to improve traffic flow during the Olympics, said Liu Xiaoming, deputy director of the Beijing Traffic Committee, at the China Planning Network First Urban Transportation Congress.

Sharing Wilson's view, Dr. Yoshitsugu Hayashi, dean of the Graduate School of Environmental Studies of Nagoya University, believed the reduction in car use should be achieved not by banning, but through incentives.

"Drivers who don't use their private cars could be given points," he said, "and the points could be exchanged for goods from online shopping."

Wetzel stressed limiting the use of company cars. "Governmental officials should also be encouraged to use public transportation or ride bicycles," he said, adding that he himself is a bicycle-rider in London.

Matthew Martimo, director of Traffic Engineering with Citilabs, said the bicycle was China's advantage. "Limiting private cars is an idea worth trying but it is just a temporary solution," he said. "The real cause of congestion is high density of people in Beijing and many have cars."

Beijing, with a population of 15 million, is home to more than three million automobiles, and the number is rising by 1,000 a day.

Professor Wilson said the Olympic Games was a great opportunity for Beijing to think about traffic problems and develop transportation, adding that the city had already been making public transport more efficient. Beijing has promised to stretch its 114-kilometer city railway to 200 kilometers before the opening of the Olympic Games.

“We are looking forward to borrowing Beijing's experiences and drawing from its lessons in preparation for the 2012 Olympics,” said Wetzel. 

51. The underlined word incentives in paragraph 4 means_______.

A. something that encourages people to try    B. online shopping

D. To show that he loves riding bicycles.

54. Which of the following may be the reason for the traffic congestion in Beijing?
