Abstract
Millions are infected with dengue yearly. We evaluated the epidemiological and clinical characteristics of pediatric patients infected with dengue in the Dominican Republic. The applicability of World Health Organization (WHO) warning signs for predicting severe dengue and mortality was also studied. This study was a cross-sectional retrospective review of patients with a clinical diagnosis of dengue. Univariate and multivariate analyses were performed to evaluate characteristics associated with severity and mortality. The study included 796 subjects: 288 subjects were classified as dengue, 290 subjects had alarm signs, and 207 subjects were classified as severe dengue. Common findings included thrombocytopenia (96%), abdominal pain (71%), and vomiting (59%). The most important factors associated with severe dengue were rash (P < 0.01), severe thrombocytopenia (P < 0.01), and anemia (P < 0.01). These signs and symptoms were also associated with mortality. This study validates the current WHO warning signs of severity. Rash and severe thrombocytopenia may be early warning signs and need additional study.
