Upward Trend in Dengue Incidence among Hospitalized Patients, United States

Abstract

International travel and a global expansion of dengue fever have the potential to increase the incidence of dengue in the United States. We conducted a retrospective cohort analysis of trends in dengue among hospitalized patients by using the National Inpatient Sample (2000–2007); the number of cases more than tripled (p<0.0001).
