Around 1 other people of 22 that COVID-19 continue to expand a life sometimes for life called myalgic encephalomyelitis / chronic fatigue syndrome (ME / CFS), suggests new research.
Previous studies have shown that the ME / CFS can be activated through viral and bacterial infections, such as the Epstein-Barr virus, which reasons mono, and Coxiella Burnetii, which reasons the new study. In January, thirteen in the Journal of General Internal Medicine, he sought to notice how much other people come to me / CFS after a Covid-19 blow.
“According to my approximate calculations, more than 7 million Americans would possibly have evolved CF / CF after Covid,” said Live Science in an email.
Pollack, who is not worried about the study, said that this estimate is based on new research, as well as the statistics of the US census workplace and the CDC domestic pulse survey, which he designed to temporarily evaluate the effects of the Coronavirus pandemia in the United. States in the United States.

The ME / CFS (previously called “Chronic Fatigue Syndrome”) affects approximately 1 out of one hundred in the United States, one of its main parts is the discomfort after extraction, in which other people suddenly worsen physical or mental effort. People with the disease occasionally delight in non -refreshing sleep, cerebral fog and orthostatic intolerance or the sudden fall of blood voltage in the state position. Doctors look to perceive the biological reasons of this substudic condition, but for the moment, there is no approved remedy.
In particular, ME / CFS presents many symptoms that overlap with a long covid, a general term that describes a diversity of physical disorders that arise or worsen after a COVVI-19 infection. Scientists still do not know that I / CFS and Long Cavid are separate diseases, said Dr. Anthony Komaroff, a medical professor at Harvard Medical School and the main doctor at Brigham Hospital and women who did not worry in the study.
Emerging evidence suggests that they can be “two examples of greater disease than humans and other animals can pass after a primary infection or a non -infectious injury,” said Komaroff of Live Science in an email.
To examine the dating between COVID-19 and ME / CFS, the researchers studied 11,785 American adults who had contracted the SARS-COV-2, the virus that reasons Covid-19. The majority of the participants were vaccinated at the time of the exam, and the maximum were recorded because the omicron variant of the virus circulated.
The team also studied 1,439 adults who had never caught Cavid-19. The prestige of this organization showed negative effects on the tests that sought the virus itself and the antibodies opposed to it. In particular, antibody degrees are minimized over time, so these tests cannot absolutely exclude infections that took their position a long time ago.
At intervals of 3 months, all participants in the questionnaires full of examination designed to stick to the imaginable symptoms of me / cfs. Then, the researchers accumulated the participants according to the seriousness of the symptoms, tracking if they had all mandatory symptoms for a diagnosis, only safe or without symptoms.
Participants with a formal ME / CFS diagnosis before they are excluded from the analysis. As a general rule, being diagnosed with ME / CFS requires express diagnosis of assembly, which come with fatigue accompanied by physical disability, discomfort after extraction, non -refreshing sleep and a cognitive or orthostatic intolerance of the disorder.
In the study, only 0. 6% of other people without a history of COVID-19 evolved a ME / SFC, 4. 5% of adults who evolved the condition at least six months after having COVID-19. This suggests that COVID-19 significantly increases the threat of coming the ME / CFS.
Pollack said that 79. 5% of other people who evolved the ME / CFS in the study were women, who aligned with previous studies that seemed that the ME / CFS and the length face women in a disproportionate way. “It will be to study later why and read about the roles of sex hormones and sexual differences in pathological immune responses to infection,” he said.
He also revealed that 88. 7% of the participants with ME / CF after COVID-19 were also diagnosed with a long cotvone.
“Long Covid and ME / CFS not only have very similar symptoms, but very similar underlying anomalies of the brain, the immune system, the metabolism of the power and the cardiovascular system,” Komaroff said. “In my opinion, Long Cavid and ME / CFS are probably examples of infection syndromes after Aiguë,” he said.
For their conclusions, the researchers used a strategy called correspondence of propensity score. This means that, in comparison, the participants of the COVVI-19 organization with participants not infected with similar demographic and pre-existing data, so that assistance minimizes the fundamental differences between organizations.

But the team pointed out that some participants would possibly have had a self / CF not followed before having COVID-19, which can also be a limitation of work. The nature founded on the exam questionnaire presented some other limitation, because the participants would possibly have fought whether their symptoms began before or after their COVVI-19.
Despite these limits, the effects that COVID-19 increase the threat of me / cfs. And currently, neither Me / Cfs nor Long Covid have approved treatments.
“The effects of this examine the focus of the pressing need for treatments,” said Pollack. “ME / CFS can be caused through triggers in addition to the SARS-COV-2, and was one of the less financed diseases for research, despite its severity. “
