肺螨病流行状况的调查与防治

Investigation and control of pulmonary acariasis pathogeny and its epidemic status

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。

Objective To know the species of pulmonary acariasis pathogeny and epidemic status in Shandong, and to explore the control measure. Methods The interview method and mites ooze liquid skin test were used to estimate the numbers of acariasis pathogeny and incidence rate in the area. Results 4 622 subjects of the normal and different professional key population were surveyed in 16 counties（ 8 prefectures） of Shandong. The total infection rate was 4.37% , and the average incidence rate was 3.89%. Among them, the numbers of the people engaged in the grain processing was highest with 13.8% of incidence rate, the following, being the grain porter（ 10.78% ）. The investigation indicated the infection with mites had main connection with time which contact breeding environment of mites. There was no significant difference between sex and age, and eight genus mites were detected in this investiga- tion. Conclusion The investigation showed the epidemic of pulmonary acariasis was relative with the special pro- fessional population, and the more working time in the breeding environment of mites, the more infection, and prevalence rate. Therefore, the personal labor protection to the specific crowd must be strengthened.
