The three sites were selected in support of multidisciplinary research goals of the Dengue Vaccine
Initiative. In addition to economic studies, these sites were chosen to provide an in-depth
picture of dengue epidemiology and transmission within high risk populations of the chosen
countries. All three sites share several common characteristics—high levels of dengue virus
transmission; stable population with low rates of migration and high rates of ethnic homogeneity;
sites are easily accessible with good health services; and local dengue control officers and
provincial public health officials are exceptionally motivated and committed to dengue research.
