| Abstract: |
| 沈阳市和平区某街办工厂1989年3月发生一起局部麻疹爆发。全部6名患者均系外地临时工,占该厂职工总人数的15%(6/40)。没有出现当地继发病例。流行病学、血清学结果表明:本起爆发是由输入性麻疹患者引起的,并且只限于临时暂居人群中流行。同时讨论了麻疹发病率处于控制水平的地区,即使有传入病例也不足引起流行。提示流动人群易造成城市局部易感人群累积,导致传染病的局部爆发。 |

| This paper reported an outbreak of measles occurred in a factory of Heping District in Shenyang in March 1989.All of the six diagnosed cases were temporarily workers, which represented 15 persent (6/40) of total workers.No secontary cases were detected. The results of epidemiological and laboratory analysis showed that this outbreak was caused by an imported case. and only spread in temporarily workers. Furthermore, we discussed that under the condition that measles incidence was limited under control level, even imported cases could not cause epidemic of measles. So, it is indicated that the flowing people can easily cause accumulation of susceptible people in cities, which may result in outbreak of some infectious diseases. |
