The first global mapping of the burden of dengue, by an international consortium led by Oxford University, marks India in red, indicating a high risk of dengue occurrence and reveals that India accounts for one-third of the infections across the world every year. Researchers have stated that climate and population spread are important factors for predicting the current risk of dengue.
