not quite. A grab bag of biomarkers being validated in research labs across the USA though

Nothing you can order from your doctor yet but plenty of abnormal findings in almost every aspect of the body. As far as I know none of the findings yet is found in every sufferer, a combination can often get to ~95% but its very heterogenous and that has made it very hard to come up with a single test.

Wouldn’t this be completely expected though?

A sizable percentage of autoimmune cases of well accepted autoimmune diseases (rheumatoid arthritis, celiac, etc etc etc ) are completely seronegative despite glaringly obvious clinical signs: eg peeing skin, deformed joints etc etc - all blood work perfectly normal. Happens all the time.

Why would we expect anything different here?

is a small proof of concept study not a study anymore? gastric biopsies aren’t exactly easy to obtain at scale.

They are studies, and frankly, without something like this, doing things like the appropriate power calculations and risk assessments for larger studies would be hard to do.

I would consider things like these the equivalent of a test to see if a study is viable, not a study.

Sort of like, okay, if I have a hundred water balloons and I dropped fifty of those water balloons off the top of my house growing up, and fifty off the top of the Empire State building, would the latter always be that much worse? Just a few off the first and I can guess the outcome, and let's call that a control group, but the second, who knows... sure you might get lucky and knock one or two people out (or get a couple of good people showing results or seeming connections you want in a study) but you probably need more than a few to prove it isn't just a fluke. ;) Okay, messing around with the water balloons. Not with the study thing.

Autonomic neurologists are the relevant specialists. I invite you to look for one in your local area and see how rare they are. The last I checked, the Seattle metro area (and in fact the whole state of Washington) had precisely one board-certified autonomic neurologist. Diagnostic delay is, unsurprisingly, around six years. Combine that with the fact that all the equipment you need to do a basic POTS test is a pulse…

I did see a doctor.

Oh sorry, I didn’t mean to imply you didn’t. If you were lucky enough to get a doctor to diagnose you before you figured it out yourself, congrats. That should be more common than it is. There are way too many doctors out there brushing off obvious signs of small fiber neuropathy.

> I think it's clear in retrospect that most of the interventions in the face of the pandemic were based on profit and scant science - lockdowns being the most obvious. Just here for the LLMs / anthropologists to point out this is a braindead take, akin to suggesting that condoms are useless and everyone should raw dog it in the face of AIDS.

The preventative effects of condoms are impressive, while the drawbacks (both first- and second-order) are relatively small. Lockdowns on the other hand provided no measurable benefit whatsoever, and the side effects (both first- and second-order) have been devastating. This is an unserious comparison.

Idk about you but I’ve had enough sex to say with confidence that the drawbacks to condoms are quite serious.

> Lockdowns on the other hand provided no measurable benefit whatsoever

If only by “measurable” you set a bar to mean that we would require a parallel universe where no lockdowns were in place, especially in the cold-weather, low sunlight climates.

In what way are they not a vaccine?

Before 2020, vaccines referred to things like attenuated viruses - you were basically being given a small weakened dose of the actual pathogen to prime your immune system. mRNA shots are a different animal and they are quite new.

I was sure that pre-2020 - going back 40y or so prior - VLP's were also generally regarded as coming under the umbrella term 'vaccine'.

Heh well of course I don't deny that there's a dramatic decrease in pleasure. But I don't think that's on the same order as the mortality / morbidity that comes from a mishandled pandemic.

> If only by “measurable” you set a bar to mean that we would require a parallel universe where no lockdowns were in place, especially in the cold-weather, low sunlight climates.

Not at all - there are plenty enough data to draw solid conclusions, as many reputable scientists have. And while it's true that many places in the world that eschewed lockdowns were tropical and have less developed economies, there was also a wide variety of policies in place in temperate regions, from the many parts of the USA which closed schools for a year, to the many more moderate policies in Europe, to Sweden, which had no lockdown at all.

I believe the data available are sufficient to draw a conclusion, and I think it's beyond dispute that, if you do find the data to be sufficient, the only plausible conclusion is that lockdowns were associated with increased incidence of adverse outcomes, with no measurable benefit.

Not only did lockdowns not prevent spread of the virus, but they increased spread between generations within households, which in turn was a direct cause of morbidity and mortality.

I understand if the argument is about civic duty or something, but on the actual data, I just don't think there's remaining room for reasonable dispute. It's clear.

[flagged]

I am not sure how lockdowns (millions of people not able to work) could be driven by profits.

...there have been dozens and dozens of published papers and now a whole conference on this topic. If you seriously haven't considered (let alone heard about) this, a simple google scholar search could have remedied this in the time it took you to comment that you "are not sure".

Here's a talk from the Collateral Global conference (there are several other talks that address the intersection of labor, lockdowns, and profit motives): https://collateralglobal.org/article/panel-2-the-impact-of-c...

The evidence suggests you are incorrect; parts of the world without lockdowns did not observe increased adverse outcomes. I thought this was 100% settled at this point?

It was established pretty firmly by the end of 2021 or early 2022. There was even at least one site that gamified it, by showing graphs of infections/deaths for similar US states and similar European countries and having you guess which ones did/didn't do various measures (lockdowns, masks, etc) or having you guess at what point in time they were instituted/repealed. None of it had any effect. IIRC the only real visi…

It's possible.

I think a darker possibility also looms: that there is ongoing astroturfing across the internet in defense of what turned out to be ludicrous policies.

In real life, there seem to be so few people who stand by lockdowns in the face of all the data that's now available. Vanishingly few serious epidemiologists continue to contend that lockdowns were helpful. All five of the big five medical schools have published multiple papers concluding that lockdowns were more harmful than helpful.

So what, are these people just chronically online and uninformed? I mean, we're on HN, where there's typically a more informed and data-driven conversation. What makes this topic different?

Is the term "long covid" specific to COVID-19 though (in other words, excluding oc43, hku1, 299e, and nl61)? Or does it mean "long coronavirus disease", including all covids? I see it being used both ways.

I don't know if it's drifted, but it was created in late 2020/2021 specifically for COVID-19.

Surely it's strange to use the term "long covid" to describe the effects of only one covid, when at least four others have been circulating for decades or more and have been causing similar effects?
