Use of Expansion Factors to Estimate the Burden of Dengue in Southeast Asia: A Systematic Analysis

摘要

BackgroundDengue virus infection is the most common arthropod-borne disease of humans and its geographical range and infection rates are increasing. Health policy decisions require information about the disease burden, but surveillance systems usually underreport the total number of cases. These may be estimated by multiplying reported cases by an expansion factor (EF).
