1988年6月至1989年5月，在冈比亚的一个城市周边沿海定居点Bakau进行了疟疾的临床和昆虫学调查。在观察期间，560名年龄从3个月到9岁的儿童中只有41人经历了疟疾的临床发作。大多数病例是在诊所发现的，而不是通过定期社区监测发现的。在巴考老城，疟疾的发病率在定居点周边地区比在中心地区更常见，这些地区毗邻典型的按蚊繁殖地。总体疟疾病例在空间和时间上没有明显的聚集性，尽管发现了三对同时睡在同一房间的儿童病例。11月雨季结束时进行的一项横断面调查显示，寄生虫病点流行率为2.0%，脾脏感染率为0.3%。所有测得的疟疾计量参数都比在该国农村地区进行的可比研究中发现的任何参数低得多，反映出在巴考发现的疟疾病媒冈比亚按蚊复合体蚊子数量较少。氯喹的消费，睡在蚊帐下，有天花板的房子，杀虫剂气雾剂的使用和燃烧的传统驱蚊剂都可能导致研究地区疟疾的低流行率。
A clinical and entomological survey of malaria was carried out in Bakau, a peri-urban coastal settlement in The Gambia, from June 1988-May 1989. Only 41 of a cohort of 560 children, aged from three months to nine-years-old, experienced a clinical episode of malaria during the observation period. The majority of cases were identified at clinics and not by regular community surveillance. In Bakau Old Town episodes of malaria were more common on the periphery of the settlement, adjacent to typical anopheline breeding sites, than in the centre. Overall malaria cases were not significantly clustered in space and time, although three pairs of cases among children sleeping in the same room at the same time were identified. A cross-sectional survey in November, at the end of the rainy season, revealed a point prevalence parasitaemia of 2.0% and a spleen rate of 0.3%. All malariometric parameters measured were much lower than any found in comparable studies undertaken in rural areas of the country, reflecting the low number of malaria vectors, Anopheles gambiae complex mosquitoes, found in Bakau. Chloroquine consumption, sleeping under bednets, houses with ceilings, the use of insecticide aerosols and burning traditonal mosquito repellents may all have contributed to the low prevalence of malaria in the study area.
