Experience and perception of risk associated with knowledge, attitudes and practices regarding dengue in Riohacha, Colombia.

Recognition of the determinants of knowledge, attitudes and practices (KAP), which could be conditioned by the experiences and perceptions of the population at risk, is essential for the control of dengue. The scope of this article is to estimate the relationship between the risk perception and dengue diagnosis experiences with KAPs on dengue in an endemic Colombian population. A cross-sectional study with multi-stage random sampling was conducted. Adjusted prevalence ratios (aPR) were estimated using regression models as measures of association. Of the 206 families interviewed, 7% know dengue is caused by a virus and less than 40% recognize other symptoms besides fever. As control strategies, 31% eliminate hatchery sites and 58% use fumigation, though 73% perceive the risk of dengue. The association was identified between the perception of the risk of dengue and knowledge about the vector (aPR = 3.32 CI95% 1.06-10.36), and the experience of diagnosis of dengue with the attitude towards dengue control (aPR = 1.61 CI95% 1.09-2.37). Risk perception and experience with dengue could become determinants of KAPs in relation to this disease.
