The prevalence of mansonelliasis was studied in the municipality of Tefé, state of Amazonas, Brazil. The prevalence (thick blood smear method) was 13.6% (147/1,078), higher in the Solimões River region (16.3%) than in the Tefé River region (6.3%). In the sampled communities in the Solimões River region, a higher density of cases was observed, as indicated by a kernel analysis (odds ratio 0.34; 95% confidence interval: 0.20-0.57). Males had a higher prevalence (χ2 = 31.292, p < 0.001) than women. Mansonella ozzardi prevalence was higher in retirees and farmers (28.9% and 27%, respectively). Prevalence also significantly increased with age (χ2 = -128.17, p < 0.001), with the highest numbers occurring in persons older than 67 years.
在巴西亚马孙州特费市对曼氏丝虫病的流行情况进行了研究。患病率（厚血涂片法）为13.6%（147/1078），索利蒙伊斯河地区（16.3%）高于特费河地区（6.3%）。在索利蒙伊斯河地区的抽样社区中，核密度估计分析显示病例密度更高（优势比0.34；95%置信区间：0.20 - 0.57）。男性患病率（χ2 = 31.292，p < 0.001）高于女性。曼氏奥氏丝虫在退休人员和农民中的患病率较高（分别为28.9%和27%）。患病率也随年龄显著增加（χ2 = -128.17，p < 0.001），67岁以上人群中的患病率最高。
