Abstract
Dengue has emerged as an international public health problem. Reasons for the resurgence
of dengue in the tropics and subtropics are complex and include unprecedented urbanization
with substandard living conditions, lack of vector control, virus evolution, and international
travel. Of all these factors, urbanization has probably had the most impact on the
amplification of dengue within a given country, and travel has had the most impact
for the spread of dengue from country to country and continent to continent. Epidemics
of dengue, their seasonality, and oscillations over time are reflected by the epidemiology
of dengue in travelers. Sentinel surveillance of travelers could augment existing
national public health surveillance systems.
