Abstract INTRODUCTION:

Chikungunya infection presents with distinct clinical features depending on the patient age group.

METHODS:

Medical records of children with positive IgM for the chikungunya virus who were hospitalized in a pediatric ward in Fortaleza, Ceará, Brazil were analyzed.

RESULTS:

Fourteen children with a median age of 4 months (36 days to 15 years) were included. All patients presented with fever persisting for an average of 5 days. The joints were involved in 6 (42.8%) children, and 8 (57.1%) children presented with bullous rash.

CONCLUSIONS:

Systemic involvement and atypical clinical manifestations characterize severe forms of chikungunya infection in children.
