title: [Serological study carried out in Cuban localities where confirmed western Nile virus infection is present].
abstract: BACKGROUND
  first infected cases caused by West Nile virus were reported in Cuba in 2004.
  
  
  OBJECTIVE
  to monitor and learn about the prevalence of the West Nile virus in those areas with confirmed cases.
  
  
  METHODS
  the study was conducted in Jatibonico municipality and in the city of sancti Spiritus. A total number of 14 persons, 8 horses and 41 birds were researched to detect antibodies to flavivirus and specific antibodies to West Nile virus.
  
  
  RESULTS
  the presence of specific antibodies to West Nile virus was confirmed in 4 samples of sera from birds and in 4 from horses. One person was confirmed as one case of asymptomatic West Nile virus infection.
  
  
  CONCLUSIONS
  the presence of specific antibodies to West Nile virus in birds, horses and persons residing in areas where there are confirmed cases showed that a local amplification cycle had been established in Cuba before this study.
