The growing burden of dengue in Latin America.
The re-emergence and subsequent failure to control dengue in Latin America provides a compelling illustration of the clinical, political and socio-economic challenges to eradicating dengue across the world. Insufficient political commitment, inadequate financial resources and increased urbanisation have contributed to the re-emergence and dramatic increase in dengue fever and dengue haemorrhagic fever in all 19 Latin American countries previously certified as free of Aedes aegypti. Difficulties with diagnosis, asymptomatic infection and the lack of effective surveillance systems account for the discrepancies between antibody prevalence against dengue and reported cases. Accurate incidence data and appreciation of the economic impact of dengue at regional, national and international levels are essential to securing political and economic commitment for dengue control efforts as well as increased scientific and social awareness. Environmental control efforts require an integrated and systematic approach at both the national and community level, while successful introduction of a dengue vaccine will require an educational programme that clearly communicates the cost-effectiveness and desirability of this interventional measure. In addition, countries must anticipate their national regulatory requirements, and vaccination strategies should be optimised according to the dengue epidemiology of each country. A broad scope is required to finance vaccination programmes to ensure individual countries' monetary shortcomings are addressed.
