本文对 1981-2 0 0 0年门诊病人肠道寄生虫感染资料进行统计分析 ,总感染率为 30 89% ( 33 6 0 7/ 10 8795 ) ;其中肠道蠕虫感染占 78 14 % ,肠道原虫感染占 2 1 86 %。主要感染虫种为蛔虫、蓝氏贾第鞭毛虫、钩虫、肠滴虫、猪带绦虫和阿米巴。 2 0年间肠道寄生虫感染率呈明显下降趋势 ,由 1981年的 46 6 1%下降到 2 0 0 0年的 12 82 % ;但近年来肠道蠕虫感染率下降速度变缓 ,而肠道原虫感染率呈现上升趋势 ,优势虫种亦由蛔虫、钩虫为主转为蓝氏贾第鞭毛虫、蛔虫居前。虽然肠道寄生虫感染 2 0年间变化较大 ,但每年的季节分布仍未打破 ,感染率以第三季度最高 ,第一季度最低。结果表明 ,目前人体肠道寄生虫病感染率还比较高 ,尤其是肠道原虫。因此 ,仍需根据季节、虫种、人群等具体情况 ,搞好肠道寄生虫病的防治工作
The data of intestinal parasites in outpatients from 1981 to 2000 were statistically analyzed. The total infection rate was 30 89% (33 6 0 7/10 8795). The intestinal worm infection accounted for 78.14% Protozoal infections accounted for 2 1 86%. Main infection worms as roundworm, Giardia lamblia, hookworm, intestinal trichomoniasis, Taenia solium and amoeba. The incidence of intestinal parasites decreased significantly from 46 6 1% in 1981 to 12 82% in 2000; however, the rate of intestinal worm infection decreased slowly in recent years, Protozoal infection rates showed an upward trend, the dominant species also by roundworm, hookworm-based giardia lamblia, roundworm living in front. Although intestinal parasitic infections varied greatly over the 20 years, the seasonal distribution of each year did not break down yet. The infection rate was highest in the third quarter and lowest in the first quarter. The results show that the current human intestinal parasitic infection rate is still relatively high, especially intestinal protozoa. Therefore, we still need to do a good job in prevention and treatment of intestinal parasitic diseases according to the specific conditions such as season, insect species and population
