传染力

Todays study estimated the contagiousness of the disease by analysing the number of people travelling to Mexico who became infected, and comparing that with a study of a Mexican village where the disease has spread.

今天的研究通过对在墨西哥旅游而受到感染的人数的分析，再对比墨西哥一个村庄疾病传播的研究，对该病毒的接触传染力进行了估计。

Since most influential " Lay Your Hands ", and then from have new song " No Worries " of contagiousness most, most beautiful tone, to put it briefly Simon Webbe singer is a more powerful star.

从影响最大的"Lay Your Hands"开始，再从最有传染力的新歌曲"No Worries"，都是最美妙的音调，简单的说Simon Webbe歌手是比较有影响力的明星。

The foot-and-mouth disease(foot-and-mouth disease, FMD) is a kind of acute, febrile,high contagious disease.FMD has very strong infectivity, and can be able to infect allcloved-hoofed animals.Once breaking out, this desease usually present epidemicity, urgentpathogenetic condition, fast and wide spread.

口蹄疫(foot-and-mouth disease，FMD)是偶蹄动物共患的一种急性、热性、高度接触性传染病，传染力极强性，一旦发生，常呈流行性，病情急，传播快，蔓延广。

Modified smallpox is assumed to have the same incubation period as ordinary smallpox, but to have a milder course of disease. The infectiousness of people with modified smallpox would be 33% of that for people with ordinary smallpox, with a case fatality rate of 10%. However, it would be harder to recognize modified smallpox and cases would be slower to withdraw to the home or go to the hospital than for ordinary smallpox. Before smallpox is recognized in the hospital (i.e., the first period), 75% of cases would be recognized on the fourth day of rash and the remaining 25% on the seventh day of rash.

Modified Smallpox一般是指比较近代的病例，同样的潜伏期，但疾病表现比较轻微，所以传染力也比较低，大概是典型天花的1/3左右，死亡率大概是10%，一般也比较不容易诊断，病例会比典型天花较晚才待在家里或到医院求诊，在病例发生发烧之后第四天产生小丘疹，到了发生疹子后的第四天，大概有75%的病例会被诊断，剩下的25%病例会在发生丘疹后的第七天被诊断。

Then we researched the existence of periodic solution of order one of this modified model by using theories of invariant set of impulsive semi-dynamical system and Brouwer\'s fixed point.

第三章考虑了一类具有非线性传染力函数的传染病模型，其中人口出生率和死亡率相同并且患病者病愈后可自然获得免疫但一段时间后免疫力也会自然丧失。

Multipartite Virus: infects both files and the boot sector--a double whammy that can reinfect your system dozens of times before it\'s caught.

复合型病毒。复合型病毒兼具开机型病毒以及文件型病毒的特性。由于这个特性，使得这种病毒具有相当程度的传染力。一旦发病，可以使计算机不断重启，破坏的程度非常可观。

May be caused by a virus, spread through saliva spatter, it is better to measles transmission power.

可能是由病毒引起，通过唾液飞溅而传播，不如麻疹传染力强。

Bifurcation and choas of the zigzag sampled phase detect frequency synthesizer;2. When incidence coefficient is afunction of the time,the parameter rogions in which the models appear choas behavior are given.

该文研究了Lin Weimin等人给出的一类具有非线性传染力的SIRS模型，证明了在某些参数区域内极限环的存在性和唯一性，以及在传染系数与时间有关时，模型存在混沌性态的参数区域。

Histopathological lesions related to swine influenza-induced lesions consisting of epithelial cells damage, airway plugging and peribronchial and perivascular mononuclear cell infiltration were present in both infected groups.

为了研究禽流感病毒H5N1是否会通过传染给猪再传染给别的哺乳动物，我们利用细胞培养基观察禽流感病毒和猪流感病毒的生长情况，并对比他们对小鼠的致病力。

Monitoring the transmissibility of pathogens from animals in humans is therefore key for early detection of epidemic spread, and for effective control.

因此，监控这些动物性病原体在人类之间的传染力对于疾病的早期诊断和控制就变得非常重要。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
