Brent Palmer's first inkling about long COVID started in the early days of the pandemic, before the term "long COVID" even existed.
Some of his friends had caught the virus while on a ski trip and returned home to Colorado with the mysterious, new illness. It was a frightening time — and an irresistible opportunity for Palmer, who studies the immune response to infectious diseases like HIV.
In particular, he was keen to see how their T cells, part of the immune system's arsenal for fighting infections, were handling the novel infection. So he started taking samples of their blood. And there was one subject in particular who intrigued him. She was still dealing with heart palpitations, chest pains and trouble breathing more than six weeks after her acute illness.
In the lab, Palmer noticed that she still had a very high percentage of these T cells directed at the virus compared to her husband who'd also fallen ill, but didn't have lingering symptoms. "They had very different responses," says Palmer, an associate professor of medicine at the University of Colorado.
Typically, T cells aimed at the virus reach very high levels during the acute infection and over time they drop off, but Palmer noticed that wasn't the case as he began studying more patients with these persistent symptoms.
"These individuals had frequencies that were 100-fold higher in some cases than the individuals that didn't have any persistent symptoms," he says.
In fact, Palmer says it was like their body was still fighting the virus. It led him to questions: "Despite the fact that they test negative in a nasal swab, is the virus still persisting in the lungs? Is it persisting in some other organ?"
Other scientists trying to uncover the roots of long COVID have asked some version of that same question for the last few years now. This theory of "viral persistence" posits that some people never fully eliminate the infection, that viral reservoirs are subsisting in the body and possibly triggering the symptoms of long COVID.
While a direct link isn't yet proven, this line of research has gained momentum as more evidence has emerged indicating that some people seem to harbor "viral reservoirs'' after their initial illness has passed. It's far from the only explanation under consideration, but some scientists see it as one of the most promising.
Same old same old. So it's looking more and more like the most likely explanation is the one that will see the fiercest defiance. Medicine has huge hang-ups about any combination of chronic and an infectious pathogen, it's considered a truism that this is not a thing, they can't handle this truth. Other than in exceptions, I guess. It's all so arbitrary. I don't see it all that often, but it's still commonly derided as the "new" chronic Lyme, the very concept isn't just taboo, it's basically toxic poison.Why viral reservoirs are a prime suspect for long COVID sleuths

deja vu?
That's not an admission of defeat, just that the first LC treatment won't be a cure. Never is the initial version of a technology perfect and medicine is no exception. Apparently they also asked what "toxicities" patients would be able to tolerate.
Actually, this annoys me a lot. Angers me, even.Believe the patient. “Say it out loud. They need to hear it,”
It literally does the opposite, because I know they're lying. And I see nothing happening. It has nothing to do with stress, the only reason people go see professionals is because they expect them to do professional-grade work. They really should think less often about stress, they don't really know what to do with the concept anyway. But very little destroys the credibility of professionals than lying on the job. Stop treating people like freaking children, it's annoying and leads to worse outcomes anyway.If their physician says, “‘I believe you, and I will work with you to try to make you better even though I know very little about this,’ stress levels go down.”

I don’t think he’s particularly prominent at the moment. He came to my attention when he wrote his book “Science Fictions: How Fraud, Bias, Negligence, and Hype Undermine the Search for Truth” in 2020. Seems to have weekly column in the i newspaper on same theme. He was at KCL but not sure if he’s still there or a full time writer/journalist now.Is he prominent in some way? He looks pretty young for the image.
Former academic ( resigned from KCL last year). He is probably the only notable UK science commentator currently writing in popular media. Mostly on the ball although he went a bit weird on Geoffrey Hinton's cassandra moment, still he has a flare for connection to common culture not evident in the usual donnish 'speaking from authority' that is UK science commentary:Is he prominent in some way? He looks pretty young for the image.
This sounds bad. Cognitive deficits = anxiety + depression. Of course!
“More than one in three people experiencing long COVID symptoms perceived such cognitive deficits, which have been found to be related to anxiety and depression.
The findings indicate that psychological issues such as anxiety or depressive disorders may play a part in some people who are experiencing long COVID, technically known as post-COVID-19 condition, or PCC.
"This perception of cognitive deficits suggests that affective issues—in this case anxiety and depression—appear to carry over into the long COVID period," said senior author Dr. Neil Wenger, professor of medicine in the division of general internal medicine and health services research at the David Geffen School of Medicine at UCLA. "This is not to say that long COVID is all in one's head, but that it is likely not a single condition and that for some proportion of patients there is likely a component of anxiety or depression that is exacerbated by the disease."
How are they so bad at this? It's the near perfection of this incompetence that is infuriating. Just so completely out of their depth that they can't even see that they are failing miserably.“More than one in three people experiencing long COVID symptoms perceived such cognitive deficits, which have been found to be related to anxiety and depression.
