Introduction

Around two fifths of the world’s population (those in tropical and subtropical countries), or up to 2.5 billion people, are at risk of dengue infection. An estimated 50 million infections occur annually worldwide, with 0.5 million of these cases being admitted to hospital for dengue haemorrhagic fever. Approximately 90% of these cases are in children aged less than 5 years. The epidemiology is, however, changing both regionally and globally.
