Estimating the dengue burden in India

Dengue is the most rapidly spreading vector-borne viral disease globally, with an increasing number of areas at risk.1 Reliable estimates of the burden of dengue are important to inform policy and research. However, quantifying the true burden globally remains elusive because surveillance systems are notoriously poor at capturing all symptomatic dengue infections, resulting in gross under-reporting. Often higher quality health systems have better reporting. Cartographical and modelling efforts estimated the global disease burden of dengue to amount to 96 million cases in 2010.
