Abstract: El virus del Oeste del Nilo (VON) género Flavivirus, familia Flaviviridae, es mantenido en la naturaleza en un ciclo enzoótico ave-mosquito-ave. Las aves son los hospederos amplificadores primarios. Humanos y caballos son hospederos incidentales finales. En humanos las infecciones se manifiestan como enfermedad febril autolimitada. También puede presentarse encefalitis o meningoencefalitis. El virus se ha establecido en Norte América y se ha documentado su circulación en México, Jamaica, República Dominicana, Guadalupe, Cuba, Puerto Rico, El Salvador y recientemente en Colombia. Se realizó una vigilancia centinela en culícidos y aves domésticas para hacer un seguimiento a la circulación en el departamento de Córdoba e identificar que especies de mosquitos estaban infectadas con el virus. Se analizaron 4942 mosquitos en 99 pooles por la técnica Vec TestTM (Medical System, Inc. Camarillo, CA) y 162 sueros de aves de corral fueron enviadas al Centers for Disease Control and Prevention Division of Vector-Borne Infectious Diseases Fort Collins, USA, para ser analizadas por MAC-ELISA y debido a las reacciones cruzadas que se dan entre el VON y otros virus del serocomplejo de la encefalitis japonesa se utilizó el test de reducción de la neutralización en placa (PRNT). No se obtuvieron mosquitos o aves positivos.
