肺螨病流行状况的调查与防治

目的掌握山东地区肺螨病病原的种类,以及肺螨病在该地区的流行状况,探讨肺螨病的防治方法。方法采用访问法、螨渗液皮肤点刺试验法,估计该地区的肺螨病发病数和发病率。结果调查省内8个地区、16个县市正常人群及从事不同行业的重点人群共4 622人,肺螨的总感染率为4.37%,平均发病率为3.89%。其中从事粮食加工人员的发病率最高,为13.80%,其次为粮食搬运工为10.78%。调查表明感染与发病主要与接触螨类孳生环境的时间长短有关。年龄及性别差异无显著性。结论调查显示肺螨病的流行与特定的职业人群有关,在存有螨类环境中工作的人员中工作年限越长,感染和患病率越高。因此,对特定人群要加强个人保护。
