A prospective survey was conducted in four villages in the central part of Benin. Dates of worm eruption were noted to precise the transmission period. In the same time, water was sampled to measure density of cyclopids in drinking water bodies. Relationships between the highest worm eruption period and cyclopid density led to precise the duration of Guinea worm latency in human which lasted from 10 to 13 months. The smallest density of cyclopids able to induce steady transmission was evaluated to 10 cyclopids per 10 liters of water. Authors did not find a proportional relationship between incidence and cyclopid density. A very few number of patients may introduce or maintain dracunculiasis in a community. Authors observed that village ponds produced an extend transmission over the dry season (from November to April). Reservoir dam induced a short period transmission in the beginning of dry season (from October to January).
在贝宁中部的四个村庄进行了一项前瞻性调查。记录蠕虫出现的日期以确定传播期。同时，采集水样以测量饮用水体中剑水蚤的密度。最高蠕虫出现期与剑水蚤密度之间的关系有助于确定几内亚蠕虫在人体内的潜伏期，其持续时间为10至13个月。能够引发稳定传播的剑水蚤最小密度评估为每10升水10只剑水蚤。作者未发现发病率与剑水蚤密度之间存在比例关系。极少数患者可能在社区中引入或维持麦地那龙线虫病。作者观察到，村庄池塘在旱季（11月至4月）造成了广泛传播。水库大坝在旱季开始时（10月至1月）引发了短期传播。
