What is dengue fever?

Page last updated 28 February 2019

A small proportion of cases can progress to severe dengue (sometimes called dengue haemorrhagic fever). A rapid deterioration can occur 2-5 days after onset of fever. The complications of severe dengue fever can lead to collapse and can be fatal. Anyone showing symptoms of dengue fever should see a doctor as soon as possible.
