Arboviruses have caused wide-spread morbidity in sub-Saharan Africa and worldwide. The objective was to present a synthesis of the findings on arboviruses infections determined from a 2013 yellow fever risk assessment survey conducted in North-Western and Western provinces of Zambia. The authors reviewed published and unpublished papers on prevalence and correlates for arboviruses. Prevalence rates for arboviruses infections were 10.3% for West Nile, 6.0% for Zika, 4.1% for dengue, 0.5% for yellow fever and 11.5% for any arbovirus infection. Respondents living in grass roofed houses were 2-3 times more likely to have any of the infections compared to those living in houses with asbestos roofs. A total of 1401 adult mosquitoes were collected comprising 28.9% Aedes, 37.0% Anopheles, 471 (33.6%) Culex and 71 (5.1%) Mansonia. The factors: roof type and visiting Angola in addition to arbovirus-specific infection correlates should be considered in developing interventions to control them in North-Western and Western provinces of Zambia.
