Dengue is an acute viral infection transmitted by Aedes mosquitoes. The disease is endemic in tropical and subtropical countries and, until recently, was considered to be exclusively an imported infection in Europe.
However, this picture is changing, as there have been cases of autochtonous dengue reported in France and Croatia in 2010 and on Madeira in 2012. In addition, neurological complications are seen more frequently and in an increasing number of foms.
Correct diagnosis can pose a problem in our geographical area due to a lack of experience with the disease on one hand and atypical disease symptomatology in our patients compared to those observed in patients from the original endemic areas on the other.
