      Dengue is a viral disease transmitted by the Aedes mosquitoes. These mosquitoes bite mainly during daytime.

       Most people have no symptoms. However, some develop symptoms after a few days to a maximum of two weeks, such as:

      • fever
      • nausea and vomiting
      • headache
      • joint and muscle pain
      • red blotchy skin rash

      In very rare cases, there is a severe life-threatening course with multiple organ failure, bleeding or fluid accumulation.

      There is no specific treatment for this disease. In travellers the risk of life-threatening complications are very low.

      Risk areas

      This disease occurs in (sub)tropical regions
      However, in recent years there have been several outbreaks in non-tropical regions, such as Southern Europe.
      There is usually no risk above an altitude of 2000metres.
