Fifteen years after our first investigation, a follow-up study was carried out with the purpose of assessing the evolution of schistosomiasis in the locality of Sabugo, Paracambi, state of Rio de Janeiro, Brazil, an area with low prevalence of the disease. The coprological techniques adopted were spontaneous sedimentation and Kato-Katz. Out of the 1356 individuals assessed, 13 (1%) were infected with Schistosoma mansoni. From those, 10 were males, 12 were over 15 years old, and at least 11 had been infected in Sabugo. All patients presented either the intestinal or the hepato-intestinal form of the disease, and 8 (61.5%) harboured light parasitic loads. In 1990, there were 27 (2.7%) infected individuals; less than half harboured light parasitic loads, with the predominance of moderate and heavy forms. Although our results indicate an improvement in the epidemiological situation of schistosomiasis in Sabugo, transmission of the disease in the locality is still active, especially among young males, and tends to be acquired during leisure activities.
在我们首次调查的15年后，开展了一项随访研究，目的是评估巴西里约热内卢州帕拉坎比市萨布戈地区血吸虫病的演变情况，该地区疾病患病率较低。采用的粪便学技术是自然沉淀法和加藤厚涂片法。在接受评估的1356人中，13人（1%）感染曼氏血吸虫。其中，10人为男性，12人年龄超过15岁，至少11人在萨布戈感染。所有患者均表现为肠道型或肝肠型疾病，8人（61.5%）寄生虫负荷较轻。1990年，有27人（2.7%）感染；不到一半的人寄生虫负荷较轻，以中度和重度感染为主。尽管我们的结果表明萨布戈地区血吸虫病的流行病学情况有所改善，但该地区疾病传播仍然活跃，尤其是在年轻男性中，且往往在休闲活动期间感染。
