BOGOTA (AFP) - – Health officials in Latin America report an earlier
than usual outbreak of potentially deadly dengue fever, and are bracing
this year for a particularly virulent outbreak of the mosquito-borne
tropical disease.
The Pan-American Health Organization (PAHO) said so far it has logged
some 146,000 cases in the first three months of the year, of which 79
have been fatal. This time last year there were some 79,000 cases of
dengue reported, with 26 deaths.
Health authorities already have declared epidemics in some Central
American and Caribbean countries, and say the spread of the disease has
been aided by climate changes.
"The year 2010 will be complicated, notably because of climactic
factors like the El Nino phenomenon," said Romeo Montoya, part of a
team of doctors who track the Aedes aegypti mosquito which transmits
the disease.
Dengue fever symptoms include high temperatures and muscle aches. In
extreme cases, hemorrhaging and death can follow.
There is no known vaccine, but officials said they are in the process
of developing one, and hope to have it ready in about five years.
According to the PAHO, the countries likely to be hardest hit by this
year's outbreak are Brazil, Colombia and Venezuela.
In Brazil, the number of dengue cases was up by 109 percent over last
year, with 21 deaths. In Colombia, 22 people have died, or around
28,000 stricken with the illness.
In Venezuela meanwhile, there have been 16,000 cases so far, said
health officials who said the number of cases appears to be rising year
after year.
"We have a (level of ) epidemic that never before existed during normal
seasons," said Violeta Menjivar, the deputy health minister in El
Salvador, where last month the government declared a national state of
emergency for dengue.
"The entire Central American region is affected."
Global warming has allowed the mosquitoes, and hence dengue fever, to
spread to areas where the disease had not previously been known.
Drought conditions in some areas also have worsened the outbreak
because people have stored water in and near their living areas,
creating breeding grounds for mosquitoes that harbor the virus.
Officials have ramped up eradication efforts including eliminating
mosquito breeding grounds and undertaking extensive fumigation in
affected areas.
