#sarscov2

2 posts2 participants0 posts today

Excellent article by @nicktsergas about Covid and immunity debt. He interviews many doctors and leading experts to explore whether repeat Covid infections are destroying our immune system.

We must keep reminding people that sarscov2 is a novel virus. It’s only been 5.5 years which is nothing in the lifespan of a brand new disease. We can’t possibly know its true long term implications, and we must have the humility to accept what we don’t know.

The rush “back to normal” and insistence that Covid is “mild” serves the ruling elite. It was shoved down our throat to keep end stage capitalism afloat, not because it was actually mild or over.

What can you do? Wear a mask. Ideally an N95 or better. Clean and ventilate the air. Donate and support local mask blocs. Stay home when you’re sick. Refuse to accept the narrative that anyone is expendable:

The COVID-19 pandemic has raised significant concerns regarding impact on the CNS.
This study, involving MRI analysis of COVID-19 effects on the pediatric brain, raises concerns about long-term effects of even mild #SARSCoV2 infection on brain development.'

NatureMultimodal MRI analysis of COVID-19 effects on pediatric brain - Scientific ReportsThe COVID-19 pandemic has raised significant concerns regarding its impact on the central nervous system, including the brain. While the effects on adult populations are well documented, less is known about its implications for pediatric populations. This study investigates alterations in cortical metrics and structural covariance networks (SCNs) based on the Local Gyrification Index (LGI) in children with mild COVID-19, alongside changes in non-invasive MRI proxies related to glymphatic function. We enrolled 19 children with COVID-19 and 22 age-comparable healthy controls. High-resolution T1-weighted and diffusion-weighted MRI images were acquired. Cortical metrics, including thickness, surface area, volume, and LGI, were compared using vertex-wise general linear models. SCNs were analyzed for differences in global and nodal metrics, and MRI proxies, including diffusion tensor imaging along the perivascular space and choroid plexus (CP) volume, were also assessed. Our results showed increased cortical area, volume, and LGI in the left superior parietal cortex, as well as increased cortical thickness in the left lateral occipital cortex among children with COVID-19. SCN analysis revealed altered network topology and larger CP volumes in the COVID group, suggesting virus-induced neuroinflammation. These findings provide evidence of potential brain alterations in children following mild COVID-19, emphasizing the need for further investigation into long-term neurodevelopmental outcomes.

This preprint seems so good! [edit: pre-proof not pre-print, it has been peer reviewed and the data passed muster, but might have formatting, grammar, and spelling tweaks]

goals were: a) to detect viral load in indoor air in different areas and floors of a separate COVID building in a hospital [...], b) to evaluate the effect of an air-cleaner in the reduction of viral load in the presence of patients, and c) to examine the correlation between viral presence in the air and particle matter burden.

their methodology is making me happy!

Their system separated aerosols into > 2.5 μm, 1.0 to 2.5 μm, 0.5 to 1.0 μm, 0.25 to 0.50 μm, and < 0.25 μm, and found

SARS-CoV-2 was detected in all different fractions and the highest viral loads were detected at stages A (> 2.5 μm) and B (1 - 2.5 μm).

however this was in open-window conditions, ie. low CO2 and higher airflow; sampling with the same equipment in households, they found

the highest amount was detected in Stage 4 (0.25 - 0.5 μm)

The data is mostly PCR but they did do some sequencing, and positively confirmed the dominant variants were stable through the study, and not confounding.

Note the air cleaner was a "Airocide (APS GCS-25 model) air purifier" which uses "photocatalytic oxidation technology" as well as 254nm UV, with no HEPA or other mechanical filter.

Also, this is vindicating for those of us pleading with folks to not immediately de-mask in the hallway:

the highest concentration was detected in COVID clinic rooms displaying a high peak of 1123 copies/m3, whereas at the corridor area showed 481 copies/m3

Also highly of note, they could not detect any virus in the areas that were upstream of negative-pressure COVID-19 care. So yes, home isolation protocols that emphasize negative pressure zones absolutely are well founded!

Origines du covid: l’Académie de médecine accrédite à son tour la thèse de l’accident de laboratoire

Après les services de renseignement américain et allemand, c’est l’Académie nationale de médecine française qui donne du crédit à la thèse de la fuite de laboratoire à l’origine de la pandémie de #SARSCoV2. Mais elle insiste tout autant sur le risque des zoonoses, accru par la destruction de l’environnement.

📗 "Viral Modernism: The Influenza Pandemic and Interwar Literature" by Elizabeth Outka

Have you wondered too: why is covid barely visible in modern media? Why do I never pick up a book with someone wearing a mask, even though it's 2020 in the story? Why do I watch tv shows set in 2021 and they act like everything is fine? I have to dig deep for any text that dares to mention the unmentionable (ongoing) SARSCoV2 pandemic, and that really bothers me.

Turns out this is not a rare phenomenon. The same happened after Spanish Flu a full century ago. This book from 2019 digs into the why of it, and then goes on to analyze the presence of the 1918 pandemic in the very few books that did mention it.

The book is divided into three parts. Part 1 zooms in on 'why?'. Why was the flu silenced in literature? Why was it such a taboo? Even if you're not interested in reading the rest of this book, this part is worth it if you've been wondering the same. It has some interesting theories. Partly the war overshadowed the pandemic. But partly it's also a problem of a lack of language and narrative. War is easy to explain: us, the goodies, fight a 'them', the baddies, and someone wins. But a virus is invisible and not well-understood. The 'enemy' doesn't invade from the outside, but spreads throughout your loved ones, penetrates your body and blurs all the lines of who's what. There was a lot of guilt about participation and ignorance. On top of the grief, there's a societal view of sickness as weakness, and of caring and ill health with femininity, which didn't help. I won't recap all of the book here, but it was a fascinating read to see why the pandemic was hidden in media, and how so much can be applied to the current times too. Plus there were lots of archival pictures that I'd never seen before!

In part 2 several books from around that era are discussed and the role of the pandemic in the story is analyzed. I was afraid that it might be too academic for me, but it was quite readable. Most notably I've gotten a more negative view of Virginia Woolf. Although she was one of the few acknowledging sickness in her literature, she also minimized Spanish Flu in daily life, not wanting to engage with it. I was also surprised to see 'look to windward' appear, which I've only known as a quote on war through Bank's books. And wow, the amount of 'living dead' analogies that pop up, interesting stuff.

Part 3 goes into two major trends that became popular post-pandemic: spiritualism and zombie tales. Both are forms of the dead coming back, one for mourning and peace of mind, the other for an outlet for fear and anger. I got quite upset reading about seances where ghosts of flu victims return to earth to exonerate their families from guilt of infection, hmpf. Either way, I thought it was engrossing. In hindsight, it all makes sense, and it helps me understand the way people behave now.

At the end the book states that we're not ready for a new pandemic, although we could be, if only we'd look reality in the eyes and prepare well. Covid started and... here we are. Millions dead, many more millions chronically ill, ableism abound, covid still around and mutating. And probably more pandemics coming at us in the near future. Every day I feel stronger about not letting this truth go unsaid. It's uncomfortable, but more tragedies will occur if the majority of people keep avoiding unpleasant realities. Don't look away, don't underestimate yourself -you can bear it and do your part to keep the people around you safe and well.

As the book says: "Reading the letters and stories told by the survivors of the pandemic —and the literary representations that simultaneously revealed and hid these very stories— launch us into new narrative streams, allowing us to hear voices long ignored in part because the viral, dust-like form at the heart of the story was itself invisible and silent."

I'm adding this book under #PlagueBook and I've also gone back and tagged all previous books that talk about pandemics that I've reviewed with that too (in a tiny effort to not lose these works into silence once again). You can view them all here:

Please stay safe and #WearAMask !

I just had a guy get angry at me for saying we’re still in a pandemic. He said it was fear mongering and “silly” to continue to take precautions.

He then went on to say his wife has Long Covid and he’s had Covid “at least 4-5 times”.

This attitude is why we’re in this mess. His own wife was disabled by Covid, and rather than adapt his behaviour he’s exposed her 4-5 additional times.

Repeat infections are devastating to those with Long Covid. Not to mention each infection does cumulative damage, and eventually you will be left disabled.

Even if you’re someone who believes it’s “just a flu”… surely you recognize people didn’t get the flu 4-5 times in a four year period? Being sick that often is an aberration, and a darn good reason to take precautions.

You know who hasn’t had COVID 4-5 times? People who are taking precautions.

Bonus tip: If you’re masking and you become infected anyways, you’ve reduced your viral load AND you’ve made sure not to infect anyone else. That’s community care & compassion and it’s worth doing.

Mask bans are ableist, discriminatory ugly laws.

Disabled advocates have been warning for years that if people didn’t help normalize masking, bans would follow

Please call legislators in New York and tell them No mask bans!

Medical exemptions aren’t enough, everyone needs the legal right to mask

The police are not doctors. They can’t determine who’s “sick enough” to wear a mask.

Many people with invisible illnesses struggle to get healthcare workers to take us seriously. We don’t want to be questioned by police.

Everyone should be allowed to mask up to prevent covid.
