The pandemic that hits the world, and that will soon occupy pages in the history books, added a new chapter this Friday with 155 new confirmed deaths.
Argentina broke one more barrier: it reached
50,029 fatalities
as a result of the coronavirus.
Shortly after the first anniversary of the arrival of this virus in the country, today we are talking about the
dynamics
of Covid 19, the
high transmissibility of some mutations
and the importance of
vaccinating
risk groups
as soon as possible
to prevent them from more contagious variants impact the fatality rate.
"Viruses vary.
This usually happens.
The issue is when it happens very quickly and when the mutations are many and significant ”,
Arnaldo Casiró, head of Infectious Diseases at Hospital Álvarez
, tells
Clarín
.
"For now, we know that there
are more transmissible variants
, such as that of Great Britain, but that they do not necessarily imply greater gravity," Casiró reviews.
Regarding mortality, it ensures that it can only translate into more deaths if that population that is considered at risk is infected.
In this sense, he points out, it will be necessary to see "
in what period
of
time
we get to vaccinate the elderly and people with comorbidities."
"As many people as possible should be vaccinated, starting with those who can develop serious symptoms," adds the Álvarez specialist.
It also refers to the latest news that warns that some vaccines would not be entirely effective against certain mutations of the virus.
"We have already seen, for example, that
AstraZeneca's would not be as effective against the South African variant
," he says and explains that, in these cases, the vaccines will have to be modified to adapt them according to the mutations.
“Once the formula is in place, transforming it based on some variant is not so complex.
In fact, with the common flu every year the vaccine is modified because
the strain changes,
"says Casiró, stressing that it is likely that with the coronavirus, vaccines will have to be updated from the appearance of new mutations.
According to him, what worries now has to do with
"the dynamics of the scene
.
"
"The bases are changing, we have to speak in potential permanently because what is a reality today can change in a few months," he highlights.
For Eduardo López, infectologist at Gutiérrez Hospital and member of the committee that advises the President, an increase in transmissibility does not imply an increase in mortality.
“
It is not that linear
.
Now many young people are getting infected and the fatality rate is falling.
The issue is that the most contagious variants, that of Great Britain, that of Manaus and that of South Africa,
do not begin to spread
among risk groups ”, he says.
"The only way to
counteract the possible impact
of mutations is with the prompt immunization of people who are more likely to develop complications if they contract Covid 19," López details.
He affirms that
we still cannot speak of community circulation
of the variants and advances that, due to a proximity issue, everything indicates that
the mutations in Brazil would spread first
, both in Manaus and in Rio de Janeiro.
Liliana Clara, infectologist at the Italian Hospital and former president of the Argentine Society of Infectology,
he agrees on the way forward although he assures that
"it will be difficult to comply with what is recommended".
"If they are more infected and the virus reaches risk groups,
mortality could also grow,
" he estimates. Although he points out that the outlook, for the moment, is uncertain. He says that today's photo has to do with what happened in the holidays and at the beginning of January and that the impact of the arrival of the new variants could only be observed in the coming weeks.
For this reason, like his colleagues, he aims to "early immunize people who may suffer severe symptoms."
"The issue is that vaccines are lacking," he adds.
And he clarifies that it is not something that happens exclusively to us.
"It occurs worldwide, but
in developing countries the situation is even worse,
" he says.
Then, he remarks that to this is added the possibility that vaccines have to be adapted to the new variants.
“If necessary, it will be possible.
There are already laboratories working on that.
What we will have to do later is
how much delay
the corrected doses would reach our country with, ”he closes.
