摘　　要：目的了解四川省土源性线虫感染状况,预测流行趋势,为制订防治对策提供科学依据。方法收集2005-2009年四川省土源性线虫病监测数据进行分析。结果用病原学方法共检查10128人,其中男性4902人,女性5226人,2005-2009年土源性线虫平均感染率分别为35.01%、34.51%、21.68%、24.49%和23.40%;2005-2009年不同地形盆周山区、川西南山区、川西平原、丘陵地区土源性线虫感染率分别为43.51%、40.64%、30.08%、25.80%和35.50%、16.87%、24.70%、16.54%;2005-2009年蛔虫、鞭虫、钩虫感染率分别为20.55%、8.88%,14.51%和7.47%、3.96%、16.72%。5年监测结果显示:钩虫、蛔虫、鞭虫的轻度感染所占比例分别为88.60%～94.16%,85.45%～100%和97.75%～100%,平均感染率为26.48%(2682/10128),50岁以上年龄组平均感染率高于50岁以下年龄组,50～54、55～59和60岁以上年龄组平均感染率分别为29.06%、33.74%和32.74%。结论四川省土源性线虫总感染率呈下降趋势,但钩虫感染仍较高,盆周山区及50岁以上人群土源性线虫病较高。Objective To understand the infection status of geohelminthes in Sichuan,predict epidemic tread and provide scientific evidence for the prevention and treatment of the disease.Methods The surveillance data of geohelminthiasis in Sichuan from 2005 to 2009 were analyzed.Results Etiological examination was conducted for 10 128 people,including 4 902 males and 5 226 females,the average infection rates of geohelminthes were 35.01%,34.51%,21.68%,24.49% and 23.40% respectively from 2005 to 2009.In 2005 the infection rates of geohelminthes were 43.51%,40.64%,30.08% and 25.80% respectively in the mountain area surrounding basin,southwestern mountain area,western mountain area,western plain and hilly area in Sichuan; but in 2009 the rates were 35.50%,16.87%,24.70% and 16.54% respectively. The infection rates of roundworm,whipworm and hookworm in 2005 and 2009 were 20.55,8.88%,14.51% and 7.47% 3.96%,16.72% respectively. The surveillance indicated that the mild infection rates of hookworm,roundworm and whipworm ranged from 88.60% to 94.16%,85.45% to 100% and 97.75% to 100% respectively,the average infection rate was 26.48% （2682/10128）. The average infection rate of people aged 〉50 years was higher than that of those aged 50 years.The average infection rates in age group of 50-54,55-59 and〉 60 years were 29.06%,33.74% and 32.74% respectively.Conclusion The overall infection rate of geohelminthes showed a decline trend in Sichuan,but the infection rate of hookworm was still high. The prevention of hookworm should be strengthened,and more attention should be paid on the prevention of geohelminthiasis among the people in mountain area surrounding basin and the people aged 〉50 years.
