The economic burden of dengue: no longer invisible or unavoidable.

In the Lancet Infectious Diseases, Donald Shepard and colleagues estimate the global economic burden of dengue, the world's most common arbovirus infection. Their report is well timed. Both the incidence and the geographic range of dengue transmission have expanded rapidly over the past three decades as a result of urbanisation, population growth, climate change, and international travel. Shepard and colleagues build on estimates from the Global Burden of Disease study, which suggest that there are now almost 60 million symptomatic dengue cases a year.
