流行病

The purpose of this article is to review the major features of the zoonotic arenaviruses from the angles of their taxonomy and classification, epidemiology and ecology, mode of transmission, clinical signs, prevention and control, etc. Which are important for the reason that viruses causing severe disease in humans are reemerging somewhere the world.

沙粒病毒是一科由啮齿动物为宿主、能够以多种方式感染并引起人类不同程度病死率疾病的RNA病毒，近来在非洲及南美出现局部流行，本文从病原学、生态学、流行病学、临床病理及预防控制等方面回顾了该病毒的研究进展。

Second, research evidence comparing the short-term satiating power of different types of liquids and of solids remains inconclusive. Numerous clinical studies have shown that sugar-containing liquids, when consumed in place of usual meals, can lead to a significant and sustained weight loss.

第一，已出版的关于含糖饮料摄入与肥胖的流行病学研究重新评定表明：大多数这种研究要么是横断面调查要么是基于目前这种趋势的一种被动性的监测，因而研究也存在着允许两者因果关系不成立情况；第二，关于不同类型饮料和固体食物短期内谁更能使人觉得饱胀能力的比较调查还没有结果。

First , a reevaluation of published epidemiologic studies of consumption of sweetened beverages and overweight shows that most such studies either are cross-sectional or are based on passive surveillance of temporal trends and thus permit no conclusions about causal links . Second , research evidence comparing the short-term satiating power of different types of liquids and of solids remains inconclusive .

First, a reealuation of published epidemiologic studies of consumption of sweetened beerages and oerweight shows that most such studies either are cross-sectional or are based on passie sureillance of temporal trends and thus permit no conclusions about causal links. Second, research eidence comparing the short-term satiating power of different types of liquids and of solids remains inconclusie.

首先，加糖饮料的消费与肥胖症之间流行病学的研究的重新评估表明：大部分如此的研究要么是片面的，要么是消极的暂时的趋势考察，因此不能得出两者之间因果关系的结论；其次，拿短期的对不同的固体能量和液体能量的满意程度做比较的研究证据也是不确定的。

Second, research eidence comparing the short-term satiating power of different types of liquids and of solids remains inconclusie. Numerous clinical studies hae shown that sugar-containing liquids, when consumed in place of usual meals, can lead to a significant and sustained weight loss.

529 Derived an expression for the saturating contact rate of individual contacts in an epidemiological model.

诱导法。 31（1993）529推导出个别接触饱和接触率的流行病模型的表达式。

Earlier this century,breakthroughs in antibiotics inspired similarly confident predictions that the ancient scourges would soon be eradicated.

在本世纪早期，抗生素方面的突破，引发了同样乐观的预测，以为自古以来人类认为是天灾的一些流行病即将被消灭。

Shuttling about the city, I thought I had discovered an epidemic of air-conditioning malfunction.

穿梭在这座城市里，我想我发现了一种流行病--空调故障。

For four years medical science staved off any general epidemic

4年来，医学击退了任何普通的流行病

Because a study led by a team of Johns Hopkins scientists finds that tailgating such feathered cargo can significantly increase your exposure to poultry-borne bacteria. The report appeared in the very first issue of "The Journal of Infection and Public Health," which will publish research on the epidemiology, prevention and control of infectious disease.

霍普金斯大学的一个科学家小组通过一项研究发现在满载家禽的货车后面行驶能显著地增加暴露于家禽携带的细菌的可能性该项研究正好发表在第一期的《传染和公共健康杂志》（The Journal of Infection and Public Health）该杂志发表有关流行病学、传染病的预防和控制方面的研究工作

This one mode pays close attention to network credence foundation of the businessman very much.

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
