What is Dengue?

Dengue viruses are spread to people through the bite of an infected Aedes species (Ae. aegypti or Ae. albopictus) mosquito. Dengue is common in more than 100 countries around the world. Forty percent of the world’s population, about 3 billion people, live in areas with a risk of dengue. Dengue is often a leading cause of illness in areas with risk.

New Dengue Vaccine

A new dengue vaccine is now available for U.S. territories and freely associated states. The vaccine is approved for use in children aged 9 to 16 years with laboratory-confirmed previous dengue virus infection and living in areas where dengue is endemic (common). The vaccine is not approved for use in U.S. travelers who are visiting but not living in an area where dengue is common.
