A study of the prevalence and intensity of malaria transmission in the lagunar area of Benin was carried out by means of repeated cross-sectional surveys of the child population. Six areas were selected: two urban areas of Cotonou, three lagunar villages and one savanna village. Slide positive rates and prevalence of antibodies to P. falciparum sporozoites were examined in June-July 1989 (long rainy season), October-November 1989 (short rainy season) and March-April 1990 (short dry season). Parasite rates in children 2 to 9 year-old showed holoendemic malaria, in the savanna village (89.4-94.2%) and hyperendemic malaria in the lagunar zone (60.7-83.5%). Levels of P. falciparum antisporozoite antibodies were higher in the sample from the periurban sector of Ladji compared with the nearby traditional lagunar villages and lowest in children living in the central urban sector. Cotonou had higher levels of malaria transmission compared with other West African cities.
通过对儿童人群进行反复的横断面调查，对贝宁泻湖地区疟疾传播的流行程度和强度进行了一项研究。选取了六个地区：科托努的两个市区、三个泻湖村庄和一个热带稀树草原村庄。于1989年6月至7月（长雨季）、1989年10月至11月（短雨季）和1990年3月至4月（短旱季）检查了疟原虫阳性率和抗恶性疟原虫子孢子抗体的流行情况。2至9岁儿童的寄生虫感染率表明，热带稀树草原村庄存在高度地方性疟疾（89.4 - 94.2%），而泻湖地区为超高度地方性疟疾（60.7 - 83.5%）。与附近传统泻湖村庄相比，来自拉吉城郊地区样本中的恶性疟原虫抗子孢子抗体水平更高，而居住在市中心地区的儿童体内该抗体水平最低。与其他西非城市相比，科托努的疟疾传播水平更高。
