[Serological survey for arboviruses in Juruti, Pará State, Brazil].
This study aimed to measure the prevalence of antibodies to arboviruses in the area affected by the Juruti Project before local mining operations. A total of 1,597 human and 85 wild animal sera were examined, using the hemagglutination inhibition test against 19 antigens from the most prevalent arboviruses in the Brazilian Amazon and IgM-ELISA for dengue and yellow fever. Positive sera for Mayaro and Oropouche viruses were also tested by IgM-ELISA. Prevalence of hemagglutination inhibition antibodies to alphaviruses, flaviviruses, and orthobunyaviruses in humans was 28.7%, while for wild animals it was 8.2% for flaviviruses. Recent infections based on presence of IgM was confirmed for Mayaro (n = 5), Oropouche (n = 23), and dengue (n = 20). The results showed active circulation of the dengue, Mayaro, and Oropouche viruses in Juruti, as well as flaviviruses in wild animals, suggesting the circulation of these viruses in the Municipality of Juruti.
