The impact of the Schistosomiasis Control Programme (PCE) in Brazil was analyzed, covering the period 1976 to 2003, using the following indicators: percentage of Schistosoma mansoni carriers detected among the population examined in the coproscopic surveys (PPS): mortality rate for schistosomiasis, per 100,000 inhabitants (TME): hospitalization rate for schistosomiasis, per 100,000 inhabitants (TIE): average age of deaths caused by schistosomiasis (IMOE). There was a 38.5% reduction in the PPS after the introduction of the PCE, attributed to the treatment of carriers. Even in hyper-endemic municipalities, such as Conde and Cuitegí, in the state of Paraíba, the PPS fell more than 50% after the first year of treatment. The parasitic burden of the carriers also decreased in the two municipalities. The TME was reduced by 63.4% and the TIE by 77.3%. The mortality rate was highest among the 50-and-above age group. The country's IMOE rose 32.3%. The IMOE was seen to be much lower in the state of Minas Gerais, where the PCE was only initiated in 1983, with very limited coverage.
分析了巴西血吸虫病控制项目（PCE）在1976年至2003年期间的影响，使用了以下指标：在粪便检查中检测出的曼氏血吸虫携带者在受检人群中的百分比（PPS）；每10万居民的血吸虫病死亡率（TME）；每10万居民的血吸虫病住院率（TIE）；血吸虫病导致死亡的平均年龄（IMOE）。在实施PCE后，PPS下降了38.5%，这归因于对携带者的治疗。即使在帕拉伊巴州的孔德和奎特吉等高度流行的城市，在治疗的第一年之后，PPS也下降了50%以上。这两个城市中携带者的寄生虫负担也有所下降。TME下降了63.4%，TIE下降了77.3%。死亡率在50岁及以上年龄组中最高。该国的IMOE上升了32.3%。在米纳斯吉拉斯州，IMOE要低得多，该州直到1983年才开始实施PCE，覆盖范围非常有限。
