Most of us now consider the Covid-19 as a more nuisance than the danger, thanks to vaccines and the past impact of the virus, all of which created our immunity.
But studies show that the multiple Covid-19 infections represent the risk of a long Covid. In the largest long pro-retaining study of young people today, scientists, led by a team from the University of Pennsylvania, report that young people who have been infected with Covid-19 were twice more likely than those who once had Covid-19 to develop long symptoms of Covid, which affect the main organs, such as heart, kidneys and lungs, as well as tastes and tastes, as well as tastes and tastes, as well as tastes, as well smell.
The ongoing research project, called Recover, is financed by the National Institute of Health and explores the influence of COVID-19 infections on long-term health. Yun Jong, a professor of biostatistics and director of the Center for Artificial Intelligence and the Synthesis of Evidence (Chase) at the University of Pennsylvania, and his colleagues focused on people 21 and younger to better understand how the reinfection of Covid-19 affects health. “People think that reinfection does not matter much and do not take them seriously,” says Chen. “Our main message is that reinfection still matters, and you must do everything possible to avoid repeated infection Taking a vaccine Or wear a mask. “

The study included data collected from more than 460,000 children, adolescents and young people from 40 pediatric hospitals, in which the infection of the first Covid-19 was diagnosed around January 2022; Some continued to develop a second infection after that. At the end of 2023, researchers compared a group with one infection with a group with a second infection, focusing on long covid -like symptoms, such as abdominal pain, respiratory disorder, changes in taste and smell, fatigue, chest pain, myocarditis or irregular palpitations.
Those who developed a second infection were more than twice as often than a group with one infection to make a diagnosis of a long chok, and re-infected people almost three times more often reported changes in taste and smell than those who had only one COVID-19 infection. This risk remained regardless of whether people were vaccinated or not, or regardless of how serious their infections were.
Nevertheless, the “vaccination status” mentioned whether people were vaccinated before the study period, and not the way they recently received a shot. (The study was also initiated before the first updated vaccines aimed at Omicron were available.) The authors emphasize that the results do not suggest that vaccines do not help reduce the risk of a long cycle. Rather, the data show that the children who were vaccinated were much less likely to receive the Covid-19 in the first place, and also with less probability were re-infected compared to unevaccinated children.
According to Chen, vaccination is an important first step in protection against a possible long cycle.
Nevertheless, the study shows that even if you are vaccinated, Reinfection represents a fairly significant risk to double your chances of developing a long Covid compared to just get it once.
“A message about how seriously you should relate to your potential risk to get the second Covid-19 infection,” Chen says. These results, along with other studies, suggest that there may be a cumulative harmful effect of re-cycle-19 on the body, and scientists are trying to better understand these potential long-term consequences. Chen also continues to study what influence can affect the first infection not only on the risk of additional infections, but also on the development of a long Covid.
