More than 2.5 billion people are at risk of contracting dengue fever. There are an estimated 50–100 million infections per year, and 500,000 hospitalizations due to severe disease. Dengue virus is a member of the flaviviridae family, transmitted to a human host by Aedes aegypti  and Aedes albopictus. Initial infections may be mild, or even asymptomatic, but secondary infections lead to more severe disease. Dr. Hata provides an overview of dengue fever and describes viral transmission, epidemiology, and pathogenesis of the infection.  She also explains laboratory testing for diagnostic markers of the illness as well as recent molecular-based testing.
