NYU: The Impact and Out-of-Pocket Costs of Dengue Illness Among International Travelers

A new study co-authored by Dr. Yesim Tozan, Assistant Professor of Global Health with New York University College of Global Public Health, was published in the American Journal of Tropical Medicine and Hygiene titled “A Prospective Study on the Impact and Out-of-Pocket Costs of Dengue Illness in International Travelers.”

Although the costs of dengue illness to patients and households have been extensively studied in endemic populations, international travelers have not been the focus of costing studies. As globalization and human travel activities intensify, travelers are increasingly at risk for emerging and reemerging infectious diseases, such as dengue. This exploratory study aims to investigate the impact and out-of-pocket costs of dengue illness among travelers.

NYU conducted a prospective study in adult travelers with laboratory-confirmed dengue and recruited patients at travel medicine clinics in eight different countries from December 2013 to December 2015. Using a structured questionnaire, researchers collected information on patients and their health-care utilization and out-of-pocket expenditures, as well as income and other financial losses they incurred because of dengue illness. The study findings suggest that international travelers incur important direct and indirect costs because of dengue-related illness. This study is the first to date to investigate the impact and out-of-pocket costs of travel-related dengue illness from the patient’s perspective and paves the way for future economic burden studies in this population.
