In order to assess the present situation of schistosomiasis in the Zona da Mata Sul, Pernambuco State, Brazil, a study was conducted in the following phases: origin, historical and temporal evolution, and basic determinants of this health/disease process; critical assessment of comprehensive intervention programs implemented by the State in the region since 1970; and a case study in 17 counties, representing 1,424 communities and 485,200 inhabitants, and Brazil's second most endemic region based on prevalence rates for schistosomiasis. Temporal series over a 14-year period were used to analyze results of intervention programs. Conclusions were: a) current positivity rates are higher than those observed in the early 1980s; b) the programs' strategy focused almost exclusively on mass treatment, thus allowing for reinfestation and occurrence of new cases; c) proposals such as the PCDEN (Program for Control of Endemic Diseases in the Northeast) aimed at decentralization to the municipal level in the 1990s were not effectively implemented, helping to leave this persistent endemic out of control.
为评估巴西伯南布哥州南马塔地区的血吸虫病现状，开展了一项分以下阶段的研究：该健康/疾病进程的起源、历史和时间演变以及基本决定因素；对该州自1970年以来在该地区实施的综合干预项目进行批判性评估；以及在17个县开展案例研究，这些县代表1424个社区和485200名居民，是巴西血吸虫病患病率第二高的流行地区。利用14年期间的时间序列分析干预项目的结果。得出的结论是：a) 当前的阳性率高于20世纪80年代初观察到的阳性率；b) 项目战略几乎完全集中在群体治疗上，从而导致再次感染和新病例的出现；c) 诸如20世纪90年代旨在下放到市一级的东北地方病控制项目（PCDEN）等提议未得到有效实施，致使这种持续的地方病失控。
