Recent Dengue in the U.S.A. (Texas)

• Dengue epidemics occurred in the USA in the 1800s and the first half of the 1900s

• Recent indigenous transmission:

  • 1980: first locally acquired cases since 1945
  • 1986: 9 cases
  • 1995: 7 cases
  • 1997: 3 cases

• Lack of recent epidemic transmission likely due to changes in life style
