According to current WHO classification, major warning signs leading to hospitalization were: abdominal pain (28/28) and persistent vomiting (15/28), the causes of severity were: hypotension (9 / 13), severe bleeding (6 / 13) and plasma extravasation with respiratory distress (4 / 13). The median patient age was 22 years, however, 8 / 13 patients classified as severe dengue were under 16 years. In conclusion, unlike previous epidemics, we found a high involvement of young people and severity in the clinical presentation predominating a high frequency of shock (hypotension) and vascular leakage, which could be related to the circulation of an emerging variant DENV-2 which is more virulent.esMedicineDengue feverVomitingAbdominal painRespiratory distressShock (circulatory)PediatricsSurgeryarticle
