I do question the accuracy of the testing. First time, late 2019. Bad cold / mild flu for a couple days followed by a month of annoying cough that wouldn't go away.

This round? Nothing. And I've supposedly been positive for 40+ days this round.

Lots of bacterial illnesses have an asymptomatic carrier states where the body’s immune system and the invading organism sort of develop their own separate peace with one another:

I suppose it is to be expected that may happen with COVID in some people as well...

Not relevant to viruses. A bacteria is an organism that might be able to live on or in your system without harming you and may be tolerated by your immune system. Obvious example is symbiotic gut bacteria.

Viruses function by re-programming specific cells to make more virus, self-destructing in the process. Your system cannot tolerate that behavior and survive.

The closest parallel is a virus which "hides out" in certain tissues where it's hard for the immune system chemistry to reach it. Obvious examples are chicken pox and herpes. If/when the immune system becomes less vigilant (time or age), the virus can then "break out" of hiding at a later date.

Respiratory viruses are not particularly prone to doing that, although it has been observed before.

AZ vaccine causing stronger side effects than mRNA vaccines. These are typical side effects, nothing adverse, but has impacted the French healthcare system because front-line providers are calling in sick after getting the AZ vaccine...

Disagree. A carrier state has been described for both hepatitis C and Hepatitis B. One could, I suppose, argue that both are really just prolonged minimally symptomatic infections, but that would appear to be a distinction without a real difference. If one can potentially spread a disease for a long period of time without themselves being greatly harmed by it, the asymptomatic carrier state label seems appropriate.

But there will always be lumpers and splitters...

Are you (they) basing that off of a positive PCR test? According to CDC, you can test positive on a PCR test for up to three months after you have had Covid - although you don't really have it anymore. That is why they don't recommend a test to "clear" you, rather a symptom based evaluation to end isolation/quarantine.

4. Recovered patients can continue to have SARS-CoV-2 RNA detected in their upper respiratory specimens for up to 12 weeks after symptom onset. (31,33,34)

Why would the govt follow their own recommendations?

Yeah. Such a deadly virus i needed a swab shoved up my nose to tell me I was sick.

First time was a cold or short lived mild flu.

Yes, they keep on shoving a pcr swab up my nose 2-3 times a week.

That's a different topic. "Asymptomatic" means you get an acute infection, have viral shedding for a while without symptoms, then resolve the infection. That's not the same as being a permanent host, which is what I thought we were talking about (ex herpes).

7%, of which the percent with active symptoms was debatable. I'll still go with "not particularly prevalent". If they have symptoms they don't count.

Yes, "killed" virus parts, including the genetic material, will take a while before your system flushes them or they degrade to being non-detectable.

I’d refer you to the veterinary literature where long term viral hosts are sort of commonplace, everything from Hoof and mouth disease to bat lyssa viruses. The mechanism appears to be a partial immunity with frequent localized breakthroughs, which probably is the mechanism for herpes simplex as well as zoster, albeit on a shorter timescale than zoster.


But it happens in humans too, and with respiratory infections.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3142679/



Many viruses have a propensity to cause latent infections. The majority of these viruses are from the family of Herpesviridae: herpes simplex virus (HSV)-1, HSV-2, varicella zoster virus (VZV), Epstein–Barr virus (EBV), CMV, human herpesvirus (HHV)-6, HHV-7 and Kaposi’s sarcoma-associated herpesvirus (KSHV/HHV)-8. Both JC and BK virus (which belong to the family Polyomaviridae), adenovirus (family: Adenoviridae) and parvovirus and adeno-associated virus (AAV; family: Parvoviridae), also have a latent phase of replication
