DENGUE FEVER and Yahoo
- Yahoo newsws service is stating that there has been a dramatic rise in
dangue fever in central america and mexico .. both types
stayed at St Theresa last year and they sprayed there also.. apparently
dengue is moving into more urban areas.. some recent stats would be
helpful .. any comments
- I live in Ciudad Colon and received a visit a few days ago from the
local Dengue fighters (CAJA people?). The told me we had dengue for
sure on my block, and handed me a couple of sheets of paper. One has
numbers as follows, dated 25 Sept 2007, for the Mora-Palmichal sector
(Ciudad Colon, Puriscal):
Cases identified to date: 48
Cases positive for hemorragic dengue: 1
Cases positive for "classic" dengue: 10
La Fila de Guayabo: 1
Sector East of Ciudad Colon: 1
Satna Cecilia: 1
Altos de San Rafael: 1
Sector West of Ciudad Colon: 2
Bajos de Loaiza Tabarcia: 1
There's a chart of "suspected cases" vs "positive cases" month by
month, which I have to assume means the # of cases people think have
happened in their houses, vs the # who bothered to go to the clinic
and get verified. The highest months of the year were January at 11
suspected cases and 3 verified, as well as August with 12 suspected
cases and 1 identified.
Also there's a chart on the prinicipal breeding grounds found from
1999 through 2003, with "recipientes" leading the pack. Recipientes I
am pretty sure just means, "stuff that holds stuff" like plastic cups
or flower pots.
Hope this helps. I read in La Nacion that the fight against Dengue is
getting very organized and the workers are out educating and trying
to curb the tide this year. This has been one of the worst years in a
long time, if memory serves.

- I hope that as they gather the statistics they also interview the
people to see where they have been, not just where they are when they
report the problem. When I see a wide dispersion of numbers in a survey
like that I begin to wonder what they have in common, like maybe a
common destination, since I would expect to see concentrations of a
disease. It is possible for example that the disease is not moving into
the urban areas and that the urban folks are more mobile and bringing
it home with them.
- I read before coming here that Dengue was
normally more common in urban areas. Most
likely, I would think, because of population

things: 1) what they feed on, the mosquitoes that is, which is people,
and 2) more available breeding grounds like rain filled spare tires,
buckets, etc and poor sanitation.Increased population of an urban
setting is not sufficient in itself, but the conditions that can
accompany it can be a contributor.
Increased world travel, and other mobility issues, is another important
variable in the spread. Also, it is drastically underreported and under
or misdiagnosed. It is likely to be more accurately diagnosed in urban
settings with more advanced medical facilities available.
This kind of research is very difficult to do well.
