流感是人类尚未征服的一种传染病。连续20年流感监测,积累了较完整资料,揭示了流感流行的若干规律,由于没有新的主要抗原变异株出现.故未发生流感大流行。但不同程度的局部流行时有发生,必须加强抗原变异株和正常人群流感抗体水平的监测,掌握其流行规律。
Flu is an infectious disease that humans have not yet conquered. For 20 consecutive years of influenza surveillance, more complete data have been accumulated, revealing some of the epidemics of influenza and no influenza pandemic has occurred since no new major antigenic variant has emerged. However, varying degrees of local epidemic occur from time to time, and it is necessary to strengthen the surveillance of influenza antibody levels in antigenic mutant and normal population, and to grasp the prevailing laws.
