| 摘 要： | 目的分析鄱阳湖区日本血吸虫病传播的影响因素。方法收集1992～1998年鄱阳湖区连续观察3年以上的血吸虫病流行村的血吸虫粪检阳性率、化疗和灭螺药物用量、易感地带面积、家畜感染率、降雨量和气温的数据。采用多元逐步回归的方法进行数据分析。结果经检验回归模型具有统计学显著性,R~2=0.735,P<0.01。可接受的变量为:上年度人群感染率的自然对数,人均易感地带面积,家畜感染率,单位易感地带面积,氯硝柳胺的用量(元)和单位感染率吡隆酮用量(元)。结论在人群感染率,人均易感地带面积,家畜感染率仍然促进血吸虫病传播的情况下,化疗和灭螺有效地降低了该类地区日本血吸虫病的传播。

| Abstract: | Objective To analyze factors affecting transmission of schistosomiasis japonica in Poyang Lake. Methods Successive surveillance data for at least three years from 1992 to 1998 at the schistosomiasis endemic administrative villages surrounding Poyang Lake were collected, including the egg positive rate by stool examination, investment on treatment of patients and mollusciciding in snail habitat, risk areas, bovine infection rate. Data on rainfall and temperature were also obtained from the relevant agencies. Step-wised regression method was employed to analyze the data. Results The regression model established is statistically significant, R2 equals 0. 735, P < 0. 01. The accepted variables affecting the transmission of the disease were natural logarithm of human infection rate in last year, risk areas, infection rate of bovine, investment values of niclosamide per risk area and value of praziquantel administered per infection rate. Conclusion Chemotherapy and mollusciciding effectively reduced schistosomiasis transmission in Poyang lake region, while the infection rate, risk areas, bovine infection rate still drive the transmission. |
