چکیده
This study was conducted to gather updated information on the occurrence of Mansonella ozzardi in Codajás, and report new information about filaria found in the riverine communities of Coari, Amazonas State, Brazil. The prevalence (thick blood smear) of infection was 9.4% and 22.0% in Codajás and Coari, respectively. Men (17.1%) had a higher prevalence than women (11.2%) (ANOVA χ2 = -4.93; p = 0.02); and the rates significantly increased with age (ANOVA χ2 = -11.51; p < 0.001) and in certain occupations such as farming/fishing (29.2%) and retired (27.6%). Municipalities located in the Solimões river have attracted large numbers of migrant workers due to oil and gas exploration in the area, and this may facilitate the spread of filariasis to other non-endemic areas.
