- Abstract
West Nile virus infection has been reported in Asia, Middle East, Europe, Americas and Africa but there is no documentation about its existence in Zambia. Therefore the purpose of this study was to determine the seroprevalence of WNV infection and its correlates in North-Western province of Zambia. Secondary data collected in a yellow fever risk assessment conducted in Zambia in 2013 was used in this study. Bivariate and multivariate logistic regression analyses were used to determine correlates for WNV infection. Unadjusted odds ratios and adjusted odds ratios with their 95% Confidence Intervals (CI) are reported. Out of a total of 1755 participants in the survey, 51.3% were females. About a third of the participants (30%) were aged 5-14 years. Overall, 2.0% of the participants had WNV infection. Having travelled to Angola was independently associated with WNV infection. Participants who visited Angola were 2.58 (95% CI [1.67, 3.98]) times more likely to have WNV infection compared to those who had not travelled to Angola. Instituting an active surveillance for the infection at border post would help in preventing further importation of the virus.
