Abstract
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.
