Seven patients required intensive care; 6 had transaminase values higher than 1000 U/L, and one patient died. Regarding serotyping, 7 cases corresponded to DEN-2. Conclusion. Severe dengue in pediatrics can occur with or without comorbidities in all age groups. The most affected target organ was the liver, although encephalitis and myocarditis may occur.
