Chikungunya Disease Awareness Among U.S. Travelers to Caribbean Destinations

This study investigated chikungunya disease awareness and its predictors, the level of adoption of recommended personal protective behaviors against chikungunya, and the health information-seeking behavior of U.S. travelers to Caribbean destinations. A cross-sectional retrospective online survey of 653 adult U.S. international travelers who visited any one of 34 Caribbean destinations was conducted in October 2015. Study participants were recruited through Amazon® Mechanical Turk. Travelers who met the inclusion criteria and gave informed consent were subsequently redirected to complete the survey which was domiciled in Qualtrics®. Results regarding health information-seeking behavior indicated that 51% of study participants had never sought information about chikungunya or any vector-borne illnesses. Only thirty percent of study participants reported having heard of chikungunya disease before participating in this study. After adjusting for the presence of other variables in a logistic regression model, gender of female, higher levels of education, more time spent at the destination, and a higher number of hours spent engaging in outdoor activities were factors significantly associated with chikungunya disease awareness. Study results also showed that twenty-two percent of study participants did not engage in any of the three recommended personal protective behaviors under investigation. Study findings highlighted a gap in existing approaches to health information dissemination vis-à-vis adoption of recommended personal protective behaviors, especially for U.S. travelers at risk for chikungunya and other emerging mosquito-borne infectious diseases in Caribbean destinations.
