Reported
Cases of Dengue in the Americas, 1980-2007
* Provisional data for 2007
| Dengue epidemics occurred sporadically in the Americas from
the 18th to the mid-20th century. Dengue has become an endemic
disease since the 1970s. The large bar shown in 1981 is due
to a massive dengue hemorrhagic fever epidemic that occurred
in Cuba that year. There has been fluctuation in disease incidence
from year to year. There was an introduction of DEN-3 into Central America in
1994. There is a continuing trend for increasing incidence of
disease. |
