摘要: 作者等于1974~1983年对菲律宾莱特湾岛达加米市的九所小学1,800名学童用粪检和环卵沉淀试验进行了日本血吸虫病年发病率的随访观察。数据用计算机处理。1974年12月~1979年3月采取改造环境措施,1979年2月后对所有虫卵阳性者进行吡喹酮化疗。结果1975~1983年的年发病率依次为22.2%、24.2%、26.9%、9.6%、28.4%、8.4%(1981~1982年未检)和6.8%。结论认为小规模环境改造防制效果很小,群众性化疗效果显著。

Abstract: The annual incidence is a ratio of positives having been converted from negatives during one year. Children at 9 primary schools at Dagami Area, Leyte in the Philip-.pines were followed up from 1974 to 1983 and the incidence rates of schistosomiasis japonica were calculated by the results of fecal examination and COP reactions amngo 1,800 children enrolled in these schools. The survey data were stored, processed and calculated by computer; The observed annual incidence rates were 22.2, 24.2, 26.9, 9.6, 28.4, 8.4, not examined and 6.8% yearly from 1975/76 school year (SY). on. As to control measure, environmental modifications with drainage by. channelling ditches In ;the rice field at the most depressed area of 50 ha in the middle of project area at 5 km radius had been conducted from Dec. 1974 to Mar. 1979. After Feb. 1979, mass chemotherapy with praziguantel has been given to egg positives of children and adults in this area. The cause of abrupt decrease of incidence to 9.6% in SY 1978/79 was thought to be due to less rain fall in the rainy season from Nov. 1977 to Jan. 1978. In the period of environmental modification, the incidence was affected little and was greatly lowered after mass chemotherapy. It was concluded that the small scale environmental modification affected little on reducing danger of infection even to the close area, although it was effective in many places in the world when it was designed and conducted at a large scale.
