American research systematically defines “long new crown” for the first time, and 12 “sequelae” symptoms are included

On May 25, “Journal of the American Medical Association” (JAMA) published a large-scale study from the United States on the sequelae of the new crown. For the first time, the study systematically proposed the definition of “long-term new coronary pneumonia” (“long new crown”) based on symptoms , which can be used as the basis for the future diagnosis of “new crown” disease tools.

Many people still experience some symptoms long after being infected with the new crown, and these symptoms are also considered as sequelae of the new crown. However, there has been no systematic research or generally accepted definition of “long crown” before.

Newly published research has identified 12 symptoms of COVID-19, the most prominent of which include loss of smell and taste, discomfort after exertion, chronic cough, brain fog, thirst, palpitations, chest pain, fatigue, changes in libido, dizziness, stomach Bowel problems, unusual movements, and hair loss.

The study included nearly 10,000 patients at 85 hospitals, health centers and community centers in 33 U.S. states. More than 8,600 patients infected with the new coronavirus were compared with more than 1,100 patients who did not have the virus.

Leora Horwitz, author of the study and a professor at the NYU Grossman School of Medicine, said: “This study attempts to come up with a specific definition for long-term new crowns, which may in the future help develop a method for doctors to diagnose patients.”

However, he also said that the definition of “long new crown” proposed by the study is still an early definition, which needs to be continuously improved, and there is still a distance from the final clinical diagnostic application. Our goal is to provide researchers with a more systematic definition. It can be used to answer questions about risk factors, such as the likelihood of “new crowns” after repeated infection with new crowns and differences in infection with different virus variants.

The study also found that “long crowns” were more common among infected people before the Omicron wave. The data show that among the patients enrolled more than 30 days after infection during the Omicron variant epidemic, the proportion of “new crown” was about 17%; More than 35%.

However, patients who were re-infected with COVID-19 during the Omicron epidemic were more likely to develop “long-term COVID-19” than patients who were infected once. Among the reinfected patients enrolled 30 days after infection, the proportion of “new crown” was 21%.

It is worth noting that people who have been fully vaccinated are less likely to develop “new crowns” than those who have not been vaccinated, no matter what kind of mutant strain they are infected with or how many times they are infected. During the Omicron epidemic, 16% of vaccinated infected people developed “long new crowns”, and 22% of unvaccinated patients developed “long new crowns”.
