1·As influenza viruses pass from one person, or bird, to another, they normally pick up random changes in their genes because of errors in viral replication.

当流感病毒由一个人或一只鸟传给另一个人或鸟时，由于病毒复制错误，它们通常会带上基因中的随机变化。

2·Antibiotics work against bacteria, not viruses, yet patients who press their doctors to prescribe them for viral infections such as colds or influenza are seldom harmed by their self-indulgence.

抗生素只对细菌起作用，而非病毒。虽然那些因病毒感染而患上感冒或流感的病人经常要求医生给他们开抗生素，但他们很少因为这一放纵行为受太大影响。

3·Swine influenza (swine flu) is an acute viral infection of the respiratory tract in pigs caused by type A influenza virus.

猪流感是一种发生在猪身上的高度传染性急性呼吸道疾病，由A型流感病毒引起。

4·Viral bronchitis may be caused by a number of common viruses, including the influenza virus.

病毒性支气管炎是由很多普通病毒引起，包括流感病毒。

5·Avian influenza (AI) is an infectious viral disease of birds (especially wild water fowl such as ducks and geese), often causing no apparent signs of illness.

禽流感是鸟类病毒性传染病(特别是鸭子和鹅等野生水禽)，通常导致无明显体征的疾病。

6·Since 2008 Google has used these inquiries to track influenza-like illnesses (ILIs) -as symptoms not backed up by a definitive viral test are officially known-among its users around the world.

从2008年开始，谷歌利用全世界用户搜索追踪类似流感的疾病(ILIS)——因为症状没得到官方认可的权威病毒实验的支持。

7·In most respects, smoke exposure worsened the host response to influenza. This animal model may be useful in studying how smoke worsens respiratory viral infections.

在更多的方面，被动吸烟恶化了宿主对流感的反应。本动物模型在研究吸烟如何恶化呼吸道病毒感染方面可能是有用的。

8·Eb treatment inhibited viral replication by binding to influenza virus hemagglutinin, thereby preventing attachment of influenza virus to cells, the report indicates.

报道还指出，EB治疗是通过与流感病毒血凝素结合，抑制病毒复制，从而阻止了流感病毒与细胞的黏附。

9·Wild birds, particularly waterfowl, are a key element of the viral ecology of low pathogenic avian influenza.

野生鸟类，特别是水鸟是低致病性禽流感病毒生态学的关键因素。

10·Influenza is a viral infection that affects mainly the nose, throat, bronchi and, occasionally, lungs.

流感是一种病毒感染，主要影响鼻、喉、气管，偶见肺部感染。
