1991年6月至1992年5月，在尼日利亚约拉附近的一个农业设施内的一个小定居点的1834名居民中进行了一项有关血吸虫病传播的社会、环境和寄生虫学因素的研究。5-12岁儿童的水接触率以及泌尿血吸虫病和肠道血吸虫病的患病率（分别占所有接触者的40.0%、98%和79%）最高，他们也是粪便和尿液污染Geriyo湖环境的主要原因。接触水的频率和持续时间遵循季节性模式，似乎受到生理和社会需求的影响，如排便、排尿和避免恶劣天气条件。需要水接触，卫生，淡水蜗牛和支持性环境之间的相互作用，确保了研究社区内的寄生虫的回收。这反过来又有助于维持一个寄生虫库，感染可能从这个库传播到该州的其他地区。本研究是血吸虫病传播动力学系列研究的一部分，该系列研究始于对同一地区淡水蜗牛生态的研究。
A study of the social, environmental and parasitological factors involved in the transmission of schistosomiasis among 1834 residents of a small settlement within an agricultural establishment near Yola, Nigeria, was carried out between June 1991 and May 1992. Water-contact rates and the prevalences of urinary schistosomiasis and intestinal schistosomiasis (40.0% of all contacts, 98% and 79%, respectively) were highest among children of 5-12 years, who were also the major contributors to the contamination of the Lake Geriyo environment with faeces and urine. The frequency and duration of water contact followed a seasonal pattern and seemed to be influenced by physiological and social needs such as defecation, urination and avoidance of harsh weather conditions. The interplay between a need for water contact, sanitation, freshwater snails and a supportive environment ensures a recycling of parasites within the studied community. This, in turn, helps to maintain a parasite bank from which infection is probably spread to other areas of the state. The present study is part of a series, on the dynamics of schistosomiasis transmission, which began with a study of the ecology of the freshwater snails in the same area.
