选择本省8个县、市已达消灭血吸虫病标准的18个村,应用COP和IHA对4361人进行调查。结果表明,距基本消灭血吸虫病10～15年的地区,人群的COP反应率和平均环沉率均降到与正常人相似的水平;因此,COP是考核消灭血吸虫病地区病情的一种可取的方法。但有血吸虫病病史者治疗后IHA的GMRT下降较慢,且仍较正常人为高,考核病情的应用价值较COP低。一个地区人群COP的平均环沉率与该地距基本消灭血吸虫病时间的长短和有血吸虫病病史人群所占比例间呈多元回归关系,根据三者间的多元回归方程,可得出COP平均环沉率的正常界值范围,为考核该地区是否达到消灭血吸虫病标准提供了参考数据。
Choosing 18 villages in 8 counties and cities in the province that have eliminated the standard of schistosomiasis, and 4361 people were investigated using COP and IHA. The results showed that the COP response rate and the average circumflex rate of the population dropped to similar levels as the normal population in the area 10 to 15 years from the elimination of schistosomiasis; therefore, COP is a desirable measure for assessing the condition of the area where schistosomiasis is eliminated method. However, there was a history of schistosomiasis IHA GMRT decreased more slowly, and still higher than normal, the application value of the disease assessment of COP lower than COP. The COP of the population in a region showed a multiple regression relationship with the duration of the basic extinction of schistosomiasis and the proportion of the population with history of schistosomiasis. Based on the multiple regression equation among the three, the average COP of the COP The normal rate range of sedimentation rate provides reference data for assessing whether the region has reached the standard of eradicating schistosomiasis.
