The biology of coronavirus COVID-19 - including research and treatments

Myth #4 is "Long COVID is all in the mind":

 

What I hate about the way this is framed is that it respects the traditional formula of: if we can't figure out the mechanism easily then it has to be psychological. It's the formula and everything behind it that's wrong. The idea that a scientific discipline could have a default explanation that is basically the modern equivalent of "God works in mysterious ways" is beyond absurd, it's basically anti-scientism.

There is no need for any of those abnormalities to be found to dismiss the nonsense about conversion disorder. It's a dumb 19th century myth devoid of any merit, it's not falsifiable, it has no scientific merit whatsoever. And this plays right into it, allowing for the never-ending process that has ruined everything before Long Covid came around, and continues to.

Hard to take anything from that Independent SAGE with Greenhalgh involved, frankly. She is probably a main reason they have been so bad at it from the start.

 

For a perhaps better overview of LC, I was pleased to watch UCSF's grand round "Unlocking the Mysteries of Long Covid" (YouTube, Oct 2022).

This was pleasing on a number of fronts, not least that UCSF has harboured some of the most egregiously minimising voices about the risks and realities of COVID and Long COVID. I liked the comment made that their research approaches are similar to the previously successful HIV model - although they hope for accelerated results rather than 20 years!

If interested but low on time capacity, I'd highlight the 2-5 minutes on hypothesised patho-mechanisms from 22:21.

 

Why are our government officials 'studying' whether we need to reinstate mask mandates with the increase of RVS, Covid and Flu overwhelming our ER's?

 

I'm seeing the term 'immunity debt' circulating on social media these last couple of weeks spreading misinformation.

Immunity debt hypothesis suggests that people's immune systems are weaker now due to lack of exposure to viruses from wearing masks, staying home and vaccines, so now our immunity is weaker to flu, RVS and Covid variants. This is dangerous misinformation.

 

Not just on social media. It's becoming official policy in some countries. Today I saw the French health minister blaming it for the current increase in respiratory illnesses. It's pretty much official in several other countries.

Basically pretending that people were living aseptic isolated lives for nearly 3 years. What nonsense. It's baffling that this doesn't get physicians screaming mad, and yet I see barely any pushback on it. Has there even been a study of how much, how long and how many people were truly at home for an extended period of time? It's been over for well over a year and other than disabled and immunocompromised almost no one was actually stuck at home in a real way, which no one cares about when it comes to us.

I've also seen this dude Prasad talk about how science and laboratory experiments aren't worth a damn, medicine needs to do RCTs of things like masks. It's hard to put in perspective exactly how much less reliable even solid RCTs are compared to real scientific experiments. There are trillions in economic activity that depend on understanding how air and gases work, how to filter particles and how to build and maintain clean rooms/plants. It's 100x more scientifically rigorous and tested in real life, and we have weirdos who think that RCTs, a significantly lesser and less reliable form of evidence, are better than actual rigorous science. What an incredible mess. Not surprisingly, same people who overhype a few anecdotes that validate their beliefs and ignore millions that don't.

It's clear that there are huge issues with scientific literacy in medicine. It's become a major problem. There would be little talk of pseudoscience like immunity debt, from the people who have pushed herd immunity no less, if not for professionals pushing for it. Same with all the pseudoscientific nonsense in the BPS ideology. This is really troubling and yet hardly anyone seems to even notice even as standards keep being degraded.

 

What doesn't get said is that even if there were a bit of an uptick in people suffering from common respiratory viruses, for the most part it doesn't make much difference. These bugs circulate every year, large parts of the population can't realistically escape being exposed to at least some of them via family at home or colleagues at work, and most cause minor, self limiting illness. And for the small minority for whom all infections pose a serious risk, they'd still be a serious risk every winter with or without the intervention of a Covid pandemic. So what's the fuss about?

Clearly nothing a little CBT won't fix.

 

My OH attended a doctor's on call / outpatient clinic ( it seemed to have morphed during daytime into a general clinic which GPs could refer to ) and was referred to dermatology for a rash ( assessed as a COVID booster side effect)

There were 4 other young women ( all under 40) at the initial clinic, all being treated for clots due to COVID.
He didn't know what the treatment was , ( he thought it was something that broke them up and let them go somewhere out of harm's way - he was a little preoccupied with himself to fully get the gist)

one woman had clots deemed " too big to break up " and had to attend weekly for 4-6 weeks for an alternative treatment.

Only women presenting - are clots more prevalent in female s?

These are the same people saying that masks aren't effective

I'm only wearing respirator N95 masks from now on. I got Covid or Influenza December 4th after going into store wearing a triple cloth mask for only 13 minutes.

I'm still dealing with this virus but it's slowly getting better.

If the market wasn't the source of COVID 19, it nevertheless constituted a serious ongoing public health threat for the spread of known and novel zoonoses. (my bolding)

"The HSM is located in the Jianghan District in the downtown area of Wuhan, the capital city of Hubei Province, and is approximately 800 m away from Hankou Railway Station, a major railway travel hub. It occupies >50,000 m2 , with 678 stalls located close to each other in extremely crowded conditions (Fig. 1A). The market is separated into two zones, the East and West Zones, with seafood and animals mainly sold in the West Zone
and livestock meat in the East Zone. Among the 678 stalls of the market, 10 stalls selling domesticated wildlife (1.5%) were identified according to sale records 24, located in the south-western corner of West Zone (8/10) and the north-western corner of East Zone (2/10), respectively (Fig. 1A). According to sale records, during late December 2019, animals or animal products were sold in these 10 animal stalls. Animals included snakes,
avian species (chickens, ducks, gooses, pheasants and doves), Sika deer, badgers, rabbits, bamboo rats, porcupines, hedgehogs, salamanders, giant salamanders, bay crocodiles and Siamese crocodiles, etc., among which snakes, salamanders and crocodiles were traded as live animals (described in detail in the Report of WHOconvened global study of origins of SARS-CoV-2 24 ).

Out of the 923 environmental samples collected in and around the HSM, 73 were found by the real-time polymerase chain reactions (RT-PCR) to be positive for SARS-CoV-2 with positivity rate of 7.9%. Cycle threshold (CT) values for the RT-PCR ranged from 23.9 to 41.7 (Supplementary Table 2). Among the 828 samples inside the HSM, 64 samples (7.7%) were positive. Of the 64 SARS-CoV-2 positive samples collected inside the HSM, 87.5% (56/64) were collected in the West Zone of the market, in particular streets from no. 1 to 8, with 71.4% (40/56) positive samples identified herein (Fig. 1A). Among the 14 samples from warehouses related to the HSM, five tested positive. This may reflect the nature of SARS-CoV-2 presence in the market during the early phase of the outbreak. Among the 51 samples from sewerage wells (Supplementary Table 1) in the surrounding areas outside the HSM, three tested positive (Supplementary Table 2). Notably, one sample (Env_0601), a floor surface swab, out of the 30 environmental samples collected from Dongxihu Market in Wuhan on January 22nd 2020, also tested positive (Supplementary Table 2, Extended Data Table 4.

Of the 110 samples collected from sewers or sewerage wells in the market, 24 samples were positive for SARS-CoV-2 nucleic acid. All four sewerage wells in the market tested positive. During the onsite investigation of the overground drainage pathway in the HSM, we found that the wastewater in the overground drainage led into the underground drainage inside the market and then flowed into the wells on the edge of the market. We then did a spot-check sampling across all the overground drains according to the principles described in the Methods (Extended Data Fig. 1). Excreta of the upper respiratory tract of infected humans and the potential animal waste would be mixed together into the overground drainage. Thus, these data suggested that either infected people and/or animals in the market contaminated the sewage or that the contaminated sewage may have further played a role in furthering the virus transmission within the case cluster in the market."
