The samples received were selected according to the presence or absence of disease which belonged to horses in the study area. During the study, a total of 118 horses were examined by ELISA detection of IgG and IgM antibodies. The incidence was 36.44% and the prevalence was 33.05%. The highest incidence occurred at the Mapancillo (28%) locality and the lowest was in La Luz (13%). Age distribution was: 1-5 years (32.55%); 6-10 years (27.91%); 11-15 years (23.26%); 16-20 years (16.28%). The 53.48% of the infected animals were males and 46.52% were female. All animals were criollos mixed race.The presence of WNV was demonstrated through the detection of IgG and IgM antibodies in blood serum of horses at the wetlands "Abras de Mantequilla" Los Ríos, Ecuador.
