The
circulation of dengue
in the City of Buenos Aires already reaches levels significantly higher than those registered in the record season of 2020. By epidemiological week 10, the number of confirmed autochthonous cases and cases under investigation was 180 three years ago,
while
now reaches -according to the latest available official data-
323
.
This is almost
80 percent more
.
These are still relatively low figures, but experts are now concerned about how the phenomenon can skyrocket depending on the
size of the potential rains
that have been announced in the district and that until this Sunday had fallen in drops.
More abundant rainfall will leave
favorable reservoirs
for the proliferation of mosquitoes.
In recent weeks, patient consultations have grown, both in the public and private health systems, due to
feverish symptoms and symptoms of dengue
, such as muscle and eye pain, among others.
But according to sources from both health sectors, there have been almost no serious cases in the City.
“There is an increase in consultations for these possible viruses and
an increase in laboratory orders
.
With the rains and the drop in temperatures, mosquitoes will appear in full and there we will see the magnitude of the problem, ” medical sources from one of the main clinics in the City
told Clarín
.
So far this season, they have already been investigated in the City of Buenos Aires
1,295 suspected cases of dengue
, out of a total of
11,066
throughout the country.
One of the highest positivities occurs in Córdoba, where
7 out of 10 tests
are testing positive.
National positivity is
43 percent
.
Sources from the Buenos Aires Ministry of Health said that "in the last two weeks, according to the dengue monitor, only 3 serious cases
were reported
and no deaths." The latest National Epidemiological Bulletin (measures the situation up to March 12), reports in other districts of “
two deceased cases
, one with a probable diagnosis of dengue in Salta and another with a confirmatory diagnosis in Santa Fe.” Both people had previous comorbidities.
The presumed cases of dengue this season, at the national level, represent levels much higher than those of the last two (after the record 2020 season).
"Regarding the notification of suspected cases, during week 10,
4,188 notifications
were registered and in the last three weeks there is a marked increase compared to the same weeks of the two previous years:
683 percent
more
than in 2022 and
159 percent. hundred more
than in 2021”, says the official document.
The provinces that up to now have confirmed autochthonous viral circulation
are
12
: Buenos Aires, CABA, Córdoba, Entre Ríos, Santa Fe, Corrientes, Formosa, Catamarca, Jujuy, Salta, Santiago del Estero and Tucumán.
On the other hand, the Ministry of Health report details that up to week 10 , 341 cases of chikungunya fever
were registered
, of which
55
have no travel history.
And five jurisdictions confirmed
autochthonous viral circulation
: Buenos Aires (in Almirante Brown, Pergamino, Quilmes and San Martín), CABA, Córdoba (in the capital), Corrientes (in Paso de la Patria) and Formosa (Tres Lagunas and the capital). .
A particularity of the current dengue season with respect to the record of 2020, is that since the cases began to grow in a sustained manner, community circulation
was imposed more precipitously
than that other time, when during a longer initial period they were preponderant. imported cases.
The anticipation of this viral circulation makes it easier for cases to grow faster, without the need for the fuse to be lit abroad.
If we add to this that for now a rather dry environment has prevailed, the climatic relief announced for these hours, with rain included, may imply
an acceleration of infections
from the accumulation of water and the multiplication of
Aedes Aegypti
breeding sites. , mosquito responsible for spreading the disease.
