In 1988-1989, as part of a co-operative programme with the local Unidad Sanitaria, two cross-sectional surveys were carried out to study the prevalence of malaria in eight villages in the rural areas near Camiri, Boyuibe and Gutierrez (Cordillera Province, Santa Cruz Department, Bolivia). Thick and thin blood films were collected from all available two- to nine-year-old children at the end of the dry season, in the first survey (252 samples), and after the rainy season, in the second survey (346 samples). The parasite and gametocyte indices increased between surveys from 1.59-25.72 and from 0.40-1.73, respectively. All infections were due to Plasmodium vivax. Both prevalence and parasite load were lower in children aged two to four years than in older children. Prevalences, parasite loads, and parasite densities were highest in rural areas near Camiri and Gutierrez.
1988年至1989年期间，作为与当地卫生单位合作项目的一部分，开展了两项横断面调查，以研究卡米里、博尤贝和古铁雷斯（玻利维亚圣克鲁斯省科迪勒拉省）附近农村地区八个村庄的疟疾流行情况。在第一次调查（252份样本）的旱季结束时，以及第二次调查（346份样本）的雨季结束后，从所有两岁至九岁的儿童中采集了厚薄血涂片。两次调查之间，寄生虫指数和配子体指数分别从1.59增至25.72，从0.40增至1.73。所有感染均由间日疟原虫引起。两岁至四岁儿童的患病率和寄生虫负荷均低于大龄儿童。卡米里和古铁雷斯附近农村地区的患病率、寄生虫负荷和寄生虫密度最高。
