If you already have it or had it, there is nothing much you can do. Maybe start eating more flaxseed and anti-inflammatory foods like turmeric and doing more sudoku.

You can’t avoid it at this point unless you live alone and become a shut-in.

I was really worried about that when DD got Covid. Still very smart and graduated Ivy. Working now at highly analytical job. No problem.

Not everyone will get it and risk is higher during an Omicron type situation compared to Delta. I am hoping the variant in Southern France peters out because it sounds a bit worse.

This is from last summer, and hopefully we get more information soon, but I thought this article provided some good explanations on what we currently think may be happening.

Mother of the Long COVID patient. My DC had mild illness without any loss of taste or smell, and yet, DC has real significant cognitive struggles.

You are grasping at straws if you think that not having loss of senses protects you from Long COVID outcomes. There are many, many studies that have come out detailing the myriad of ways the body invades different body tissues and that the virus stays in the body for months even in patients who have mild infection. Like other viruses before it (flu, zika, ebola, HIV, HPV, Herpes), COVID is likely to have long term effects in at least some portion of the population and because of the millions of infected people, even if only 1% or 10% have long term issues, that’s still a ton of people.

It’s not grasping at straws to posit that previous variants that were more likely to produce olfactory symptoms may be more likely to affect olfactory related brain areas. It also stands to reason that people who get Covid after being vaccinated will not experience the same invasion of multiple organ systems. A lot of the data being published right now is from before vaccines were widely available.

We should be concerned but not panicked, based on available evidence. Speaking of evidence, please point me to the studies showing that the virus stays in multiple organs of people who had a mild illness. The only studies. I have seen on that used patients who died from Covid. You can’t look at viral mRNA or RNA on tissues of people who are still alive.

The study that showed the persistence in the organs did include people that had mild cases. They died of something else and were autopsied. What was noticeably lacking was signs of inflammation despite signs of Covid, so many question if it will be lying dormant for years and possibly reactivated. Or not. I wish they had checked for Lewy bodies on those patients.

You should catch up on your reading, neuroscientist….

“ We show that
SARS-CoV-2 is widely distributed, even among patients who died with asymptomatic to
mild COVID-19, and that virus replication is present in multiple pulmonary and
extrapulmonary tissues early in infection. Further, we detected persistent SARS-CoV-2
RNA in multiple anatomic sites, including regions throughout the brain, for up to 230 days
following symptom onset. Despite extensive distribution of SARS-CoV-2 in the body, we
observed a paucity of inflammation or direct viral cytopathology outside of the lungs.
Our data prove that SARS-CoV-2 causes systemic infection and can persist in the body for
months.”

more:

“ We show SARS-CoV-2 disseminates across the human body and brain early in infection
268 at high levels, and provide evidence of virus replication at multiple extrapulmonary sites during
269 the first week following symptom onset. We detected sgRNA in at least one tissue in over half of
270 cases (14/27) beyond D14, suggesting that prolonged viral replication may occur in extra-
271 pulmonary tissues as late as D99.”

and

“ Finally, a major contribution of our work is a greater understanding of the duration and
330 locations at which SARS-CoV-2 can persist. While the respiratory tract was the most common
331 location in which SARS-CoV-2 RNA tends to linger, ≥50% of late cases also had persistence in
332 the myocardium, thoracic cavity lymph nodes, tongue, peripheral nerves, ocular tissue, and in all
333 sampled areas of the brain, except the dura mater. Interestingly, despite having much lower
334 levels of SARS-CoV-2 in early cases compared to respiratory tissues, we found similar levels
335 between pulmonary and the extrapulmonary tissue categories in late cases. This less efficient
336 viral clearance in extrapulmonary tissues is perhaps related to a less robust innate and adaptive
337 immune response outside the respiratory tract.
338 We detected sgRNA in tissue of over 60% of the cohort. While less definitive than viral
339 culture23,24, multiple studies have shown that sgRNA levels correlate with acute infection and can

340 be detected in respiratory samples of immunocompromised patients experiencing prolonged
341 infection24. These data coupled with ISH suggest that SARS-CoV-2 can replicate within tissue
342 for over 3 months after infection in some individuals, with RNA failing to clear from multiple
343 compartments for up to D230. This persistence of viral RNA and sgRNA may represent infection
344 with defective virus, which has been described in persistent infection with measles virus –
345 another single-strand enveloped RNA virus—in cases of subacute sclerosing panencephalitis25.
346 The mechanisms contributing to PASC are still being investigated; however, ongoing
347 systemic and local inflammatory responses have been proposed to play a role5. Our data provide
348 evidence for delayed viral clearance, but do not support significant inflammation outside of the
349 respiratory tract even among patients who died months after symptom onset. Understanding the
350 mechanisms by which SARS-CoV-2 persists and the cellular and subcellular host responses to
351 viral persistence promises to improve the understanding and clinical management of PASC.”

Funny how you chose not to copy the info about the patient cohort. Most of the cases were from before vaccines were available and all of them were hospitalized and died of Covid. Extended Data Table 2 shows that the vast majority needed to be intubated.

But go ahead and explain how this can be generalized to healthy, vaccinated adults with mild Covid. You can read all the studies you want but it won’t be worth much if you can’t properly interpret the findings.

PP is directly quoting the studies though - not interpreting them. Agree that most of the patients were very sick, but it's not the PP who wrote the part about mild and asymptomatic. It's directly from the abstract, so your beef is directly with NIH.

Again, quoting from the study, “ Our results collectively show while that the highest burden of SARS-CoV-2 is in the
313 airways and lung, the virus can disseminate early during infection and infect cells throughout the
314 entire body, including widely throughout the brain. While others have posited this viral
315 dissemination occurs through cell trafficking11 due to a reported failure to culture virus from
316 blood3,22, our data support an early viremic phase, which seeds the virus throughout the body

317 following pulmonary infection[b]. Recent work by Jacobs et al.22 in which SARS-CoV-2 virions
318 were pelleted and imaged from COVID-19 patient plasma, supports this mechanism of viral
319 dissemination. Although our cohort is primarily made up of severe cases of COVID-19, two
320 early cases had mild respiratory symptoms (P28; fatal pulmonary embolism occurred at home) or
321 no symptoms (P36; diagnosed upon hospitalization for ultimately fatal complications of a
322 comorbidity), yet still had SARS-CoV-2 RNA widely detected across the body, including brain,
323 with detection of sgRNA in multiple compartments. Our findings, therefore, suggest viremia
324 leading to body-wide dissemination, including across the blood-brain barrier, and viral
325 replication can occur early in COVID-19, even in asymptomatic or mild cases. Further, P36 was
326 a juvenile with no evidence of multisystem inflammatory syndrome in children, suggesting
327 infected children without severe COVID-19 can also experience systemic infection with SARS-
328 CoV-2.[b]

It is true that vaccinated individuals do not appear to be a part of this study; however, given the findings in mild, asymptomatic and juvenile patients, I think it’s wishful thinking to believe that vaccination and mild illness protects a patient fully from the early viremic seeding phase theorized in this paper.

Do we know? No. Is vaccination at least partially protective? Probably. But this dissemination appears to happen in Wk1 even in those with mild illness, so I wouldn’t be surprised if we found out it is happening in vaccinated patients who have symptoms and test positive but recover in a week and never need medical care.

This news is scary but so many people have had covid now. Many kids at my DS's school, my friends, entire families...many people have it don't realize it or never received an official test.

I have a friend whose husband tested positive with a mild case last year (low grade fever, cold symptoms). One of the kids got mild cold symptoms- wife and other child, no symptoms, but they assume that the whole family caught it and didn't test...just isolated and followed the CDC procedures at that time.

When the kids go back to school and DH returns to work next week, I'm sure it will be our turn. We don't have much option to isolate ourselves-- DH would be fired if he refused to come into the office and my DS's school is resuming in person without a remote option.
