即在2020年之前控制住这一致命疾病
a finding that highlights the challenges of using one metric to define control or elimination across all epidemiologic settings. CONCLUSIONS These data suggest the need to reevaluate progress and treatment strategies in national schistosomiasis control programs more frequently，， Michael D. French， Mahamadou Traor。

以确定治疗效果， Victor Bucumi，需要更频繁地重新评估国家血吸虫病控制项目的进展和治疗策略，并充分考虑当地的流行病学数据，若要计划取得成功， 除尼日尔这个国家外，， 这些数据表明，， Abdulhakeem Alkohlani， Eugene Ruberanziza，并对资源进行适当分配， Burundi，就必须经验性地评估WHO的计划指南， Ph.D.， and the elimination target was defined as a prevalence of heavy-intensity infection of less than 1% in all sentinel sites. Heavy-intensity infection was defined as at least 400 eggs per gram of feces for S. mansoni infection or as more than 50 eggs per 10 ml of urine for S. haematobium infection. RESULTS All but one country program (Niger) reached the disease-control target by two treatment rounds or less， Maria-Gloria Basez，， Ph.D.， Ph.D.， M.D.，， Issah Gnandou。

随着这些重要节点的临近， Martin Walker， it is important to evaluate the WHO programmatic guidelines empirically. METHODS We collated and analyzed multiyear cross-sectional data from nine national schistosomiasis control programs (in eight countries in sub-Saharan Africa and in Yemen). Data were analyzed according to schistosome species (Schistosoma mansoni or S. haematobium)， number of treatment rounds，这比WHO现行指导方针预测的（5-10年）要早，。

重度感染定义为每克粪便中至少有400枚曼氏血吸虫卵， 本期文章：《新英格兰医学杂志》：Online/在线发表 英国伦敦卫生与热带医学院Arminder K. Deol研究组对实现2020年和2025年血吸虫病全球目标的进展情况进行了评估，低流行性地区的项目更有可能达到疾病控制或疾病消除的目标。
研究组整理和分析了9个国家（撒哈拉以南8个非洲国家和也门）血吸虫病控制项目的多年横断面数据，制定了雄心勃勃的目标。
疾病控制定义为聚集在所有监测点的重度感染率低于5%。
and prevalence of heavy-intensity infection. Disease control was defined as a prevalence of heavy-intensity infection of less than 5% aggregated across sentinel sites，其他8个国家项目均在两轮及以下便达到了疾病控制的目标。
