The people who have the Covid-19 plus d’une fois ont davantage de risques d’avoir a series of serious health problems that celles who are not eu qu’une seule fois, souligne ce jeudi la première grande étude sur theme.
Repeat infections increased as the virus mutated, but the long-term health effects of these reinfections were unclear until then. A new study published in the journal Nature Medicine examines for the first time how reinfection increases the risk of long-term health problems from Covid.
The US researchers analyzed the anonymous medical records of 5.8 million people in the US Department of Veterans Affairs’ national health care database.
Heart and lung problems, brain ailments, kidney diseases, diabetes…
More than 443,000 people tested positive for covid at least once between March 1, 2020 and April 2022. Of these, 41,000 had covid more than once. In detail, more than 93% had a total of two infections, while 6% had three and almost 1% had four. The remaining 5.3 million have never contracted Covid.
When the researchers compared the health outcomes of the different groups, they found that “people who were reinfected were at higher risk for all sorts of unwanted health problems,” Ziyad Al-Aly, an epidemiologist at Washington University told St. Louis and lead author of the study.
Heart and lung problems, for example, were more than three times more common among people who had been reinfected. Reinfection also promoted brain disease, kidney disease and diabetes, according to the study.
The authors, however, acknowledged some bias in their study, including the fact that it mostly involved older white men.
