A recurrence of a COVID infection is more serious than the first

A new study finds that the risk of death, hospitalization and serious health problems from COVID-19 increases with reinfection, regardless of vaccination.

The study examined U.S. Department of Veterans Affairs data collected from March 1, 2020 through April 6, 2022. It included information on 443,588 patients with SARS-CoV-2 infection, 40,947 with two or more infections, and 5.3 million people without infection. . Most of the study subjects were male.

Re-infection with COVID-19 increases the risk of contracting both Seeing “The results and long Covid disease,” said Dr. Ziad Al-Aly of Washington University School of Medicine in St. Louis, adding that this was evident “in unvaccinated, vaccinated and booster people.”

Infected patients had a twofold risk of death and three times the risk of hospitalization compared to individuals infected only once. The study, published in the journal Nature Medicine, found that patients also had an increased risk of a number of other health problems. The problems affected the lungs, heart, blood, kidneys, bones and muscles. Re-infection also increased the risk of mental health and brain and nerve disorders.

“Even if it was someone Before infected and vaccinated – meaning they have dual immunity from a previous infection plus the vaccines – are still susceptible negative said Al-Aly, who is the lead author of the study.

Vulnerability means being easily affected or hurt by something.

The study found that people with frequent infections were three times more likely to develop lung problems, three times more likely to develop heart disease, and 60 percent more likely to develop brain or nerve disorders. The risk was higher in the first month after re-infection, but still clear after six months.

The overall risk of reinfection increased with the number of infections, the researchers said, even after examining differences in COVID-19 variants such as Delta, Omicron and BA.5.

“We are starting to see a lot of patients come into the clinic very eagerly Invincible“They asked, is re-infection really important?” Al-Ali told Reuters. The answer is yes, it certainly is.”

He added that before the season, which often includes travel and indoor gatherings, people should be aware that getting injured again is a serious matter and they should take steps to avoid injury.

Al-Aly explained that the researchers are not suggesting serious measures, “but maybe if you are traveling on a plane, wear a mask.” Or, if someone is in a food store, “Think, the person near you might be lean impervious And if you wear a mask you may help protect them.”
