Nigeria Field Epidemiology and Laboratory Training Programme, Abuja.
Background: In Nigeria not much is known about West Nile virus (WNV) in pigeons. This study determined the involvement of household-reared pigeons in the circulation of WNV in Nigeria.
Methods: It was a cross-sectional study. Serological detection was done using competitive enzyme-linked immunosorbent assay and a pretested interviewer-administered questionnaire was used to collect information on risk factors related to WNV in households.
Results: From the156 households enumerated, 376 pigeon serum samples were collected and tested for antibodies. A total of 3.5% (13/376) of the pigeon sera were positive. Risk factors for WNV in households indicated that not having a blocked or stagnant gutter that is not flowing, and having mosquito nets at the windows and doors were found to be protective (OR=0.69, 95% CI, 0.21-2.29; OR=0.46, 95% CI, 0.14-1.56).
Conclusions: Household-reared pigeons contribute to the epidemiology of WNV. There is need for further studies in other species of birds, and education of the populace about its zoonotic transmission.
