冬天所见的急性呼吸道疾患大部分是由病毒引起的。近20年来研究的主要目的是寻找是否有一种特殊病毒能作为急性呼吸道疾患各种临床表现的最常见病因,以及寻找主要的死亡原因,从而制订出有效的控制方法。现在看来这种简单的希望显然永远不会实现而且也没有一举就消灭急性呼吸道疾患的疫苗。在急性呼吸道疾患爆发流行中已经分离出150种以上不同的病毒,而所获得的能对抗一种病毒的抗体对其他任何一种病毒少有交叉防御作用。而且大多数病毒均能引起几乎全部呼吸道疾患的临
Most of the acute respiratory diseases seen in winter are caused by viruses. The main purpose of the research in the past 20 years is to find out whether a particular virus can be used as the most common cause of various clinical manifestations of acute respiratory diseases and to find the main causes of death so as to formulate effective control methods. It now appears that such a simple hope will obviously never be realized and there is no vaccine to eliminate acute respiratory disease in one fell swoop. More than 150 different viruses have been isolated in the outbreak of acute respiratory disease, and the antibodies that are available against one virus have little cross-protection against any of the other viruses. And most viruses can cause almost all respiratory problems
