After the WHO declared the
end of the health emergency
due to the
Covid
pandemic this Friday -and, a separate note, dengue shows signs of a decreasing impact every week after the record peak-, the world continues to turn.
Respiratory viruses seem to begin to resume their
seasonal logic
and the flu as a figurehead for winter will say once again present.
During the first months of the year, the number of registered flu cases was
among the lowest in the decade
and that trend continues for now.
According to the data from the latest national Epidemiological Bulletin, the accumulated incidence only exceeds those registered in 2020 and 2021, years in which Covid naturally
took over
the airspace.
The current behavior of the flu is
already different
compared to the overflow of last year, when a historical record of cases was registered in
three atypical waves
, at the beginning, middle and end of the year.
Now, everything indicates that the influenza virus would have returned to put on the usual corset.
Although we will have to wait to determine if the normalization is consolidated.
The good sign is that the
incidence of flu cases
for this time of the year, compared to the same period in other non-pandemic years, is located well
below
and always in the so-called "safety zone".
Currently there are
315 cases
per 100,000 inhabitants, while the average for the decade -excluding the pandemic- was
467 per 100,000
.
The record from 2014 to this part was precisely in 2022, when at this point there were
680 cases
per 100,000 people.
However, and despite this optimistic panorama, there is a key fact that is worrying and that is the
slow pace
with which
vaccination
against influenza is advancing.
The bad sign is that although the campaign began in mid-March, almost two months ago, the proportion of the
vulnerable population
that has been immunized
is low
.
If it continues like this, that would result in fewer barriers to stop the virus.
There are 2.3 million doses of the trivalent adjuvanted influenza vaccine for those over 65 years of age.
According to data from the Ministry of Health, until May 2, 29.3 percent
of health personnel and
18.5 percent
of pregnant women
had received the vaccine .
Furthermore, only
11.9 percent
of children between the ages of 6 months and two years received the full regimen.
The
vaccination deficit
in general in the post-pandemic period has already been pointed out and the campaign against the flu would not be the exception.
The flu vaccine is indicated for health personnel, people aged 65 and over, pregnant and postpartum women, girls and boys from 6 to 24 months of age, and individuals from 2 to 64 years of age with risk factors such as obesity, diabetes, respiratory diseases
,
diseases cardiac, congenital or acquired immunodeficiencies, oncohematological patients, transplant recipients or people with chronic renal failure on dialysis.
All of them are guaranteed free flu vaccine.
The rest who want to apply it must pay for it.
The importance of
more people being vaccinated
- beyond their personal condition - is that it contributes to
"herd immunity"
and, consequently, to the fact that the influenza virus circulates less.
The Ministry of Health urged the population to take advantage of the time of vaccination to do so against the
flu
and
Covid
in
a single procedure
.
He spoke of "putting special emphasis on the opportunity to
co-administer
vaccines as the main strategy in prioritized groups, remembering that the protection conferred by vaccination is not immediate, but rather requires at least
14 days
to generate adequate protection."
Regarding the vaccine against Covid, the Federal Health Council agreed that from now on it will be
annual
for those under 50 years of age and
biannual
for those over 50 and the population at risk.
The WHO recommended that these boosters be made with the
bivalent messenger RNA
vaccines from Pfizer or Moderna, adapted for the Omicron variant.
Regarding the flu vaccine, the Government reported that
9,300,000 doses
of the trivalent flu vaccine were purchased, of which 5,500,000 correspond to the trivalent adult, 1,500,000 to the trivalent pediatric and 2,300,000 are doses of trivalent adjuvanted influenza vaccine, intended for people 65 years and older.
Now they have to ensure that
those who have it indicated
are not distracted.
