Abstract

A seroparasitological study of malaria was carried out in two of the more important islands of Equatorial Guinea, Bioko (ex Fernando Poo) and Annobón. The study involved a randomly-chosen population of children aged from two to nine years. In Bioko 1130 children were chosen from 29 of the 51 villages on the island; in Annobón 185 children were chosen from the capital town, where all the population lived. Indirect immunofluorescence tests (IFAT) showed a prevalence of malaria infection of 29.8% in Bioko and 55.7% in Annobón. The parasitic prevalence (malaria index) was 26.6% and 55.1% respectively, and the splenic index was 57.0% and 54.6% respectively. The results indicate that this is an area of stable hyperendemic malaria, which may benefit from an antimalarial programme.

摘要

在赤道几内亚两个比较重要的岛屿——比奥科岛（前称费尔南多波岛）和安诺本岛开展了一项疟疾血清寄生虫学研究。该研究涉及随机选取的2至9岁儿童群体。在比奥科岛，从该岛51个村庄中的29个村庄选取了1130名儿童；在安诺本岛，从首府城镇选取了185名儿童，该岛所有人口均居住在首府城镇。间接免疫荧光试验（IFAT）显示，比奥科岛疟疾感染率为29.8%，安诺本岛为55.7%。寄生虫感染率（疟疾指数）分别为26.6%和55.1%，脾脏指数分别为57.0%和54.6%。结果表明，这是一个疟疾稳定高流行地区，可能会从抗疟计划中受益。
