目的了解和掌握近年广州地区不同职业人群蠕虫分布状况及流行特点,为制订防治策略提供依据。方法根据本市各区、县级市的地理分布,连续6年分期分批选择不同职业的人群作为调查对象,用清水沉淀法、盐水漂浮法或改良加藤氏厚涂片粪检蠕虫;用透明玻璃胶纸粘贴法检查市区、农村部分幼儿蛲虫。结果共粪检28376人,感染4315人,感染率15.21%。其中华支睾吸虫感染率6.59%,钩虫感染率4.08%,蛔虫感染率4.78%,鞭虫感染率1.54%。县级市及近郊区感染率较市区高,分别为22.77%和9.92%。职业中以农民感染率最高,为19.68%;环卫工人和饮食服务业次之,感染率分别为8.11%、7.37%。在检查13947人中,男女感染率分别为27.22%和17.95%,感染率随着年龄增长而增高。幼儿蛲虫检查998人,感染79人,感染率7.92%。结论华支睾吸虫及农村的土源性线虫仍是今后重点防治的寄生虫。采取有效的综合防制措施,加强宣传教育,改变人们不良的饮食习惯,提高个人防护意识,可降低人群蠕虫感染率。

Farmers have the highest infection rate of 19 68%.The infection rates of the environment and health care workers and the food service works were 8 11%and 7 37%respectively.In 13 974 investigations, the infection rates of male and female were 27 22%and 17 95%respectively.Seatworm examination was performed in 998 infants, and 79 infants were infected with an infection rate of 7 92%. Conclusions The future prevention and treatment of the helminthes infections should be concentrated on the Clonochis sinensis and the clay origin Eelworm.
