Dengue Bulletin

Salta province in northern Argentina. This was
the southern most extension of dengue noted
to that point (29) .
Similarly, Easter Island, Chile and
Hawaii (USA) recently suffered outbreaks of
dengue. Both outbreaks were caused by
DEN-1, and probably had been spread by
travellers from Tahiti, the American Samoa
or Western Samoa. More than 100 cases of
dengue have been reported from Hawaii
since 2001 (30) and more than 130 cases have
been reported from Easter Island in 2002 (25) .
Although small in comparison to the
outbreaks elsewhere in the Americas, these
Dengue in the Americas
mark new territories of dengue invasion in
2001-2002.
Table 3 lists dengue cases by country
from 1997 to 2002. Note that Brazil,
Colombia, Costa Rica, Cuba, Ecuador,
Guatemala, Honduras, Mexico, Nicaragua,
Peru, Puerto Rico and Venezuela have had
major dengue outbreaks or epidemics during
this period. Over 320,000 cases of dengue
fever were reported annually from the
region since 1997. In the first quarter of
2002, there were already more than
400,000 cases reported.
