"“We ran Epstein-Barr virus serological tests on COVID-19 patients at least 90 days after testing positive for SARS-CoV-2 infection, comparing EBV reactivation rates of those with long COVID symptoms to those who never experienced long COVID symptoms,” says lead study author Jeffrey E. Gold of World Organization in a media release. “We found over 73% of COVID-19 patients who were experiencing long Covid symptoms were also positive for EBV reactivation.” Long COVID and severe COVID-19 infections associated with Epstein-Barr virus reactivation

Investigation of Long COVID Prevalence and Its Relationship to Epstein-Barr Virus Reactivation by Jeffrey E. Gold 1,*, Ramazan A. Okyay 2, Warren E. Licht 3 and David J. Hurley
Abstract:
Coronavirus disease 2019 (COVID-19) patients sometimes experience long-term symptoms following resolution of acute disease, including fatigue, brain fog, and rashes. Collectively these have become known as long COVID.

Our aim was to first determine long COVID prevalence in 185 randomly surveyed COVID-19 patients and, subsequently, to determine if there was an association between occurrence of long COVID symptoms and reactivation of Epstein–Barr virus (EBV) in 68 COVID-19 patients recruited from those surveyed.

We found the prevalence of long COVID symptoms to be 30.3% (56/185), which included 4 initially asymptomatic COVID-19 patients who later developed long COVID symptoms. Next, we found that 66.7% (20/30) of long COVID subjects versus 10% (2/20) of control subjects in our primary study group were positive for EBV reactivation based on positive titers for EBV early antigen-diffuse (EA-D) IgG or EBV viral capsid antigen (VCA) IgM. The difference was significant (p < 0.001, Fisher’s exact test). A similar ratio was observed in a secondary group of 18 subjects 21–90 days after testing positive for COVID-19, indicating reactivation may occur soon after or concurrently with COVID-19 infection.

These findings suggest that many long COVID symptoms may not be a direct result of the SARS-CoV-2 virus but may be the result of COVID-19 inflammation-induced EBV reactivation.

Abstract:
The objective of this study was to detect the Epstein–Barr virus (EBV) coinfection in coronavirus disease 2019 (COVID-19). In this retrospective single-center study, we included 67 COVID-19 patients with onset time within 2 weeks in Renmin Hospital of Wuhan University from January 9 to February 29, 2020.

Patients were divided into EBV/SARS-CoV-2 coinfection group and SARS-CoV-2 infection alone group according to the serological results of EBV, and the characteristics differences between the two groups were compared. The median age was 37 years, with 35 (52.2%) females.

Among these COVID-19 patients, thirty-seven (55.2%) patients were seropositive for EBV viral capsid antigen (VCA) IgM antibody. EBV/SARS-CoV-2 coinfection patients had a 3.09-fold risk of having a fever symptom than SARS-CoV-2 infection alone patients (95% CI 1.11–8.56; P = 0.03). C-reactive protein (CRP) (P = 0.02) and the aspartate aminotransferase (AST) (P = 0.04) in EBV/SARS-CoV-2 coinfection patients were higher than that in SARS-CoV-2 infection alone patients. EBV/SARS-CoV-2 coinfection patients had a higher portion of corticosteroid use than the SARS-CoV-2 infection alone patients (P = 0.03).

We find a high incidence of EBV coinfection in COVID-19 patients. EBV/SARS-CoV-2 coinfection was associated with fever and increased inflammation. EBV reactivation may associated with the severity of COVID-19.

I can´t read anything or write much, so I listen to this
Me, too!

I listened to part of this yesterday. Amy's story of her childhood sounded almost just like my version.

Except Amy got her ME treated and Amy is now well. She certainly speaks rapidly.

And I have not, over the last 68 years, solved my medical mystery. So I am sharing this made me feel bad, and like I am some type of failure, unable to work a medical system, unable to get any help or meaningful treatments.

so just sharing my petty, unevolved emotional response.

Its just wonderful we have this amazing motivated smart person working on our troubles.

Epstein-Barr Virus May Be Leading Cause of Multiple Sclerosis
Multiple sclerosis (MS), a progressive disease that affects 2.8 million people worldwide and for which there is no definitive cure, is likely caused by infection with the Epstein-Barr virus (EBV), according to a study led by Harvard T.H. Chan School of Public Health researchers.

Their findings will be published online in Science on January 13, 2022.

“The hypothesis that EBV causes MS has been investigated by our group and others for several years, but this is the first study providing compelling evidence of causality,” said Alberto Ascherio, professor of epidemiology and nutrition at Harvard Chan School and senior author of the study.

“This is a big step because it suggests that most MS cases could be prevented by stopping EBV infection, and that targeting EBV could lead to the discovery of a cure for MS.”

MS is a chronic inflammatory disease of the central nervous system that attacks the myelin sheaths protecting neurons in the brain and spinal cord. Its cause is not known, yet one of the top suspects is EBV, a herpes virus that can cause infectious mononucleosis and establishes a latent, lifelong infection of the host.

Establishing a causal relationship between the virus and the disease has been difficult because EBV infects approximately 95% of adults, MS is a relatively rare disease, and the onset of MS symptoms begins about ten years after EBV infection.

So how do they tell reactivation? More antibodies and antigens? Is it just a threshold that they assume means reactivation? Would you expect more antibodies in a person with an overactive immune system? Is this any different to the old studies showing the same for ME? And also showing the same for ME with hhv6 and coxsackie b?

Researchers have several ideas about why this happens. "It’s clear that genetics play a role in autoimmune disease, but researchers still don’t fully understand how. For example, having a family member with lupus or multiple sclerosis (MS) raises your risk of getting these diseases. Some families have multiple members affected by different autoimmune diseases. However, genetics alone isn’t enough to cause autoimmune disease."
“We know that genes are important, but they aren’t everything,” Orbai says. “You can have family members with lupus or MS and never get them yourself. You can even test positive for lupus-specific DNA and still not have the disease.”
"It’s possible that autoimmune disease occurs based on the immune system’s ability to handle stress. Orbai says that this is an area of intense research. “When does the stress on your body exceed your immune system’s ability to handle it? If we knew this, it could be the key to preventing autoimmune disease before it develops.”

A positive PCR test. I had EBV and HHV6 PCR tests before and after my COVID vaccines - HHV6 was negative before but positive after. Zoster is also known to be reactivated and I wouldn't be surprised if all herpesviruses reactivated. I also had HHV6 and EBV reactivate after my cancer treatment, triggering my ME/CFS.

SarS-CoV-2 induces oxidative stress.

SARS-CoV-2 infection pathogenesis is related to oxidative stress as a response to aggression

From the first study: "Finally, we suggest a therapeutic strategy to reduce oxidative stress using antioxidants, NF-κB inhibitors, Nrf2 activators, and iron complexing agents. We believe that this hypothesis can guide new studies and therapeutic strategies on this topic."
