I’ve already been infected with Ómicron. Can I be infected again?
Specialists admit that a reinfection with the same variant can occur, but believe that it will not transform major complications. Doctors and infectious disease specialists explain to CNN Portugal what is known about this subject

Anyone who has now managed to ‘escape’ SARS-CoV-2 and has been infected for the first time with an Ómicron variant is not free from getting the same variant again, which is milder in symptoms and severity, but much more contagious than as variants. previous.
“It is not at all impossible [uma reinfeção]. If an Ómicron variant remains [em circulação]it is possible that the person will be reinfected with the same variant after a period of time”, begins by telling CNN Portugal Luís Tavares, doctor and coordinator of the Infectious Diseases Unit at Hospital Lusíadas in Lisbon, without saying how long it can take between a infection and another, as the duration of immunity is still uncertain.

override immunity in addition to Delta and continua variants, responsible for the vaccine of the most years of resistance in recent years, although most can go ahead, confer the vaccine most cases of resistance in the last, and confer the shield the vaccine of previous years -protector against serious disease – the Ómicron variant can overlap itself, even if strains of the same variant can occur.

“There are two different strains, two variations. There is a suspicion that a person infected with one lineage can be infected with the other”, explains Gustavo Tato Borges, president of the Association of Public Health Physicians.
Manuel Ferreira Magalhães Also Manuel Ferreira Magalhães, a pediatric pulmonologist and university professor, had already explained that “due to the inexistence of the immune system’s ability to produce a permanent defense of SARS-CoV-2”, it is possible that the person can be variant twice by the same variant, since “there is no immune memory”.
How frequent is a double Omicron infection?
Not for now, because a good part of the cases that are happening now concern people who have been infected so far, with a Delta variant.
However, Óscar Felgueiras, a mathematical specialist in epidemiology at the University of Porto, adds that “there are reports on the matter”, but argues that “the important question”, for now, is to know “to what extent this is frequent, if we are talking about ” of a pattern or not”.

Looking at the case, which already assumes the covid-19 and is evolving to the most endemic phase, as Filipe Fro told CNN Portugal, Ó Felgueiras considers the cases of reinfection that have been reported by a Denmark there may be due to the the fact that the country already has “a completely dominant form variant”.
“We had Delta and Ómicron reinfection microlevels of the same age and they do not move away with the same family”, originated Gustavo from the family, which was created by Gustavo Tae, who does not continue: “Although we have no sepsis alerts BA.2 [nova linhagem]the difference you can determine with BA.
Are there more risks with a double infection with Ómicron?
It depends. Not allowing information about this variant, but in light of what is known today, it is as possible that the damage is not as severe as with other variants. However, for immunosuppressed people and for those who are not yet vaccinated, the risks are always a reality.

“This second line remains light, therefore, being re-infected with Ómicron as it does not bring, so far, major complications”, says Gustav Tato Borges, who continues: “with what ends up, it will not make any difference if [as pessoas] may or may not appear to be a good disease and the microorganism resistant”.
Regarding the potential impact on health systems, Óscar Felgueiras says that “at the outset it does not seem to be too much of a risk”. “I would say that it will constitute another protective layer”, considers the mathematician.
How long does the Ómicron solution last?
This is one of the doubts of the scientific community and is due to the fact that Ómicron has been circulating for a short time among the population.
“There is no information that increases the risk of reinfection in advance”, which increases the risk of reinfection in advance Luís Tavares.
On this point, Gustavo Tato Borges reports reports also in South Africa, in which “there were in variants with variants from the same family, but there is a certain uncertainty regarding the duration of the Ómicrofetan immunity”. Also in Israel data on people who have been infected twice by Ómicron are starting to emerge.

Ómicron doesn’t crash Ómicron, but other variations?
Again, it is not yet known. Although long-term analysis has already been taking place with the new coronavirus for 24 months, the truth is that this variation was discovered at the end of its period and only as limited to the possibility of its temporal and only as CNN Portugal Gustavo Tato says. Borges: “Ómicron is at a very early stage”.
If a Delta variant is at stake, Ómicron could be a blockade, according to a study developed by a team of scientists at the African Research Institute, which gives those recovered from an infection of the Ómicron variant can achieve later infections of the variant Delta.
“If another variant appears, the possibility of a reinfection is more plausible”, says infectious disease specialist Luís Tavares.
Regarding this topic, Óscar Felgueira considers that “in a population with a large and comprehensive vaccine, as with Portugal derived from Ómicron, this will initially strengthen the immunity of the population”. However, the mathematician that “we will never know for sure what will come to a new variation, but it will be more expected with the passage of time the population becomes more resistant”.
