Search Methods
Published, peer-reviewed literature, published and unpublished country reports, and the World Health Organization (WHO) library database, including Dengue Net, were reviewed for 1960–2010 for the key terms "dengue" and "Africa." In addition, we examined peer-reviewed published literature and other sources to determine the extent of disease among travelers returning from Africa. We searched for publications in English by using MEDLINE and EMBASE electronic databases, Euro Surveillance, and ProMED-mail posts. A review for dengue reports in languages other than English did not find any reports that would change the conclusions of this article.
Additionally, references in each paper identified during searches were checked. Those references not already identified by the search were reviewed. Abstracts presented at international forums were included if they contained epidemiologic, entomologic, or virologic data pertaining to dengue in Africa.
