Portuguese. O objetivo do presente foi estimar a soroprevalência de anticorpos contra o vírus da EEE e da WEE utilizando como unidades de análise os eqüídeos e as propriedades rurais do tipo familiar do município de Uruará, PA. Os anticorpos contra o vírus das EEE e da WEE foram pesquisados pela microtécnica de soroneutralização. As seguintes prevalências de animais sororeatores para os diferentes vírus foram observadas: EEE 27,37% (IC 15,33 - 39,21%), WEE 1,05% (IC 0,06 - 6,78%). Para as propriedades obtivemos as seguintes prevalências: EEE 53,12% (IC 35,03 - 70,49%), WEE 3,12% (IC 0,16 - 18,00%).
