Dengue Fever (or Breakbone Fever) Flavivirus types DEN1, DEN 2, DEN3, and DEN4 Historical Background The first cases of dengue fever were described in Australia in 1897. It was first reported in the United States in 1922, in South Africa in 1927, in Greece in 1928, and in Taiwan in 1931. In Thailand, the first cases were registered at the end of World War II. The disease surfaced in India with an epidemic in 1966, which started in the Philippines in 1953 and spread throughout the main cities of Southeast Asia. In 1964, 4,000 cases were identified in Bangkok. An epidemic struck Ivory Coast, Burkina Faso, and Senegal in 1980–1981. Another outbreak occurred simultaneously in the West Indies, mainly targeting Cuba. New Caledonia was hit by outbreaks of dengue fever in 1989 and 1995. In both cases, the type 3 virus was predominant. Epidemics of dengue fever occurred in Costa Rica in 1993, Laos in 1994, Venezuela in 1995, and India in 1996.
