Among 713 equids sampled in northeastern Brazil during 2013–2018, West Nile virus seroprevalence was 4.5% (95% CI 3.1%–6.3%). Mathematical modeling substantiated higher seroprevalence adjacent to an avian migratory route and in areas characterized by forest loss, implying increased risk for zoonotic infections in disturbed areas.
