The research was supported by the Bioethics Committee of the University of Los Llanos. 613 samples of Creole and quarter-mile equine horses, intended for sports and work activities, with an age range of 2 to 15 years, were analyzed using serological and molecular tests in the transects: Villavicencio-Restrepo-Cumaral, Sanmartín- Castilla la Nueva-Granada and Puerto López-Puerto Gaitán, analyzed in 62 pools and 213 mosquitoes.
