Things are not quite right a few months after you recovered from Covid.

You feel unwell when you stand up. You feel like you're spending time even with routine tasks. It doesn't feel like a good night's sleep anymore.

Is it possible to have long carbon dioxide? It might not be easy.

According to a recent study published in the journal Frontiers in Immunology, a mild or even an asymptomatic case of COVID can cause some viruses to come back, potentially leading to Chronic Fatigue Syndrome.

Unvaccinated patients who had experienced Covid were found to have circulating Epstein-Barr viruses. In patients with chronic fatigue syndrome, the immune system was struggling to fight off the viruses.

Chronic Fatigue Syndrome is thought to be caused by non-COVID pathogens. Symptoms of the condition include fatigue, brain fog, dizziness, and unrefreshing sleep.

Experts say that the symptoms of long COVID patients could be described as chronic fatigue syndrome. According to a study done in October, COVID can lead to suppression of the immune system, which in turn can lead to reactivation ofviruses that are linked to chronic fatigue syndrome and long COVID.

It's possible that "long COVID" in some infections isn't a new thing, but that it's related to Chronic Fatigue Syndrome.

In 2020, top U.S. infectious disease expert Anthony Fauci said that long COVID may be associated with a post-viral syndrome.

‘We’re still not doing that’

According to Dr. Alba Miranda Azola, co-director of the long COVID clinic at the University School of Medicine, it is possible that COVID causes Chronic Fatigue Syndrome.

Her clinic does not check for the reactivation of Viruses in COVID patients. She doesn't think it's worth giving patients antibiotics or antivirals if there is a chance they will cause symptoms

There isn't enough evidence to support that treatment.

Azola said that the patients who were prescribed such treatments didn't see much improvement. She asked her infectious disease colleague if it was a good idea to test for and treat long-term COVID patients with infectious diseases.

She recalled him saying that they weren't doing that.

The long COVID clinic is run by a pulmonologist at National Jewish Health in Denver. The condition is a lot of different and complex.

There isn't a consensus definition for long COVID. There are hundreds of possible symptoms and no single explanation can explain them all.

It is difficult to know the cause of the association. It's possible that long COVID causes reactivation, not that reactivation causes long COVID.

Most COVID patients respond well to treatments that their clinic uses, so Dr. Galiasatos doesn't routinely test his patients for infectious diseases.

He said they might test for other things if a patient doesn't respond to treatment.

The immune systems of a lot of people may be weakened by COVID.

He believes that the immunodeficiency allows the viruses to come back.

According to the October study, scientists still don't know if chronic fatigue syndrome is caused by aviruses or if it is just a symptom. Researchers don't know what role the viruses play in the development of COVID.

Few options, for now

It doesn't really matter which patient has long COVID or chronic fatigue syndrome, experts say, at least not right now There is no specific drug that can be used to treat the symptoms of both.

Azola doesn't order the test because it's the main reason There isn't any treatment for chronic fatigue syndrome. Treatments can help with symptom management and improve quality of life, but they are not a cure.

If researchers can show that the conditions are caused by residual viruses, it will be possible to eradicate them.

After the H1N1 flu infections, Azola has several patients who were diagnosed with chronic fatigue syndrome. She says that their fatigue symptoms are worse now that they caught Covid.

She said that they remember the things that worked for them before, learning how to pace themselves, staying out of what she calls the corona-coaster, and crashing for days. They have implemented strategies that worked for them in the past.

A deeper understanding of the condition and tailored treatments could be achieved by the end of the year.

According to the October study, long COVID is caused by a persistence of the SARS-coV-2 virus, which causes COVID after acute infections. It will try to find out if Paxlovid reduces or eliminates long COVID symptoms.

Azola said that they were starting to move into the trial-treatment phase.
