Fact check: Cold, flu, flu shot will not cause positive COVID-19 tests
"A positive test for COVID-19 only means you have antibodies for the flu and/or the common cold," reads a post on Instagram. "DONT TAKE THE TEST!"

"Stop testing yourselves!!! If you've had a cold (coronavirus) you will test positive for COVID 19. If you've had the flu. You will test positive for COVID. If you've been vaccinated for influenza, you will test positive for COVID," reads a post on Facebook.

The users behind the posts did not respond to requests from USA TODAY for comment.

This ran in my local newspaper this morning. I just can not believe that almost a year later this garbage goes around, and people believe it.

What if a majority of those people already had Covid? They are not going to catch it again? And spread it? My kids have all had Covid now, they are over it. Is there a reason why people who have had Covid should stay home?

I would guess that a certain percentage of those people that traveled have covid, not a majority. I think most of those people traveling did not have Covid, but quite a few of them were in fact asymptomatic carriers of the virus---

@mickey2942 That's a very deep understanding of all what is to come. Great questions.

We'll be moving into a phase where folks have had, and/or have had vaccines.

I will never ever be able to find the reference (perhaps someone else here can).... but IIRC the antibody levels are ??? many times higher with the vaccine than natural infection.

That said.
How should they mask... for others still just to allay fears vs. being seen as an anti-masker?

Two to 4 months after infection... would they get reinfected. Dunno Yet even with the vaccines, (see above interview with Moderna and many posts) it hasn't been proven if folks can get it, and are protected like your kiddos... yet may transmit.

The science isn't out on that yet. At least from what I've seen. But yet, this is a question that is going to become more and more common! The messaging from leaders and scientists need to get on the same page as to expectations next year as is going to be VERY confusing to many who aren't as exposed to info as we are... and I'm not sure even after all I've read.

Also begs... if you have the vaccine, can you no longer wear a mask. Should you wear a mask just for that "Typhoid Mary type" transmission where may be in your nose, but aren't infected/get sick but could pass forward?

BTW.. I asked weeks ago and never heard... has ANYONE seen IgA studies done ANYWHERE? (IgM and IgG studies yes, but IgA comes later through secretions such as mucous membranes, breast milk etc.... I've seen nothing on such)

If anyone here has seen any IgA studies, can you post please? It's lacking yet very important MOO. Perhaps @10ofRods and others in the area can comment on?

I think much is still unknown about that

"At this time, whether you have had COVID-19 or not, the best ways to prevent infection are to wear a mask in public places, stay at least 6 feet away from other people, frequently wash your hands with soap and water for at least 20 seconds, and avoid crowds and confined spaces."

Scottsdale, Arizona

"...the district does not have enough teachers or substitutes to cover teacher absences on Monday."

"[Superintendant] Menzel also askes families to "voluntarily quarantine if you and your students traveled during the Thanksgiving holiday or if you hosted or attended a large gathering beyond your immediate family."

Edited to add:
To me, if you have that many teachers not wanting to come to work after Thanksgiving holiday, or for any other reason, you need to sit down for a spell and think about that

I don't know, but this merits further inquiry. My kids have had Covid, they stayed home, quarantined, isolated, and were released from Isolation by the county health department.

So, why can't they go out to dinner? Travel to Las Vegas? They are young, healthy, over Covid.

Yes!

Dr. Campbell is so disappointed that MSM doesn't cover vitamin D (probably because not many studies iykwim).. and at 22:33 in this video from yesterday states that ALL care home in England will be given FREE vitamin D from January to April by the PHE.


And remember the swiss cheese model we had months ago, he has shown a new one!

This Swiss cheese model looks good to me.

My SIL’s doctor told her that she is safe from reinfection 6-8 weeks out. But I don’t know. A client of mine who got it early, in March, wears a mask everywhere now.

It seems like they’d be safe now. I mean doesn’t the vaccine do a similar thing to getting infected?

I think those who have had it and those who get the vaccine should be able to return to normal for the most part. But everyone should wear masks in crowded areas for now. Because being immune from reinfection doesn’t mean they can’t carry the virus, does it? Plus, it should just be standard until we get this under control.
 
  • #610
From what I understand from information posted and I honestly cannot remember where in the media I read it, once a person has Covid they can get it again because the antibodies do not stay with the person forever. The antibodies are short lived....a few months at the most.

So my question is this: The vaccine, just how long is that good for? Is it only good for a short time just like if you had Covid?

And....what about those who cannot take the vaccine? Because of what chemicals are put in the vaccine to insure its shelf life, like Sulfites used for this use or when dyes are used in medications people have reactions to dyes. Not much is being revealed as to just what is in vaccine. Trying to ask a doctor or pharmacist about what ingredients, active or inactive are in a medication is useless. Doctors say they don’t have time to research but still want you to take a medication that may be harmful. Pharmacists just look at the information sheet inside the package which does NOT give all the ingredients. It appears there are many people,not able to take this vaccine.

For me, too much remains uncertain. I'm sure we had it in March, but I havent seen anything definitive about immunity time scales. If anything, we are probably more cautious than a lot of people because we dont want to get it again. I still feel battered from round one!

I don’t think that’s true. The traces of preservatives in vaccines are miniscule. The things that are in large enough quantities to cause a reaction (eggs, and for the syringe tip, sometimes latex) are screened in all patients. There aren’t many people who are unable to get vaccines.

The CDC has a list of ingredients for all vaccines. I’m sure these vaccines will be added as well:

Sure. I don't mean to start an argument, but the CDC keeps moving the goal posts on Covid. I think that people who tell everyone to stay home, and make a lot of judgment on people who don't "stay home", are ignoring a significant section of the population who have had Covid, and have been released from the Health Department to go back to work.

If anyone here has seen any IgA studies, can you post please? It's lacking yet very important MOO. Perhaps @10ofRods and others in the area can comment on?

Really interesting questions. There are some studies on IgA, but not many studies of that type that would answer the question about people who were already infected and whether they should wear masks. If there's a mask mandate, everyone has to wear a mask (regardless of whether they are transmitting or capable of getting COVID, due to mere logistics - if the mandate is to be enforced, everyone has to do it). There's no way that hospitals or airplanes or casinos can trust people to be honest or even knowledgeable about their own disease status.

Thing is, we just don't know whether people can briefly reacquire COVID, be asymptomatic and still transmit COVID. I found this:

https://onlinelibrary.wiley.com/doi/full/10.1002/jmv.26422

It shows that not all of the recovered patients had IgA antibodies. In fact, it showed that different groups of patients have different antibody profiles. Without the neutralizing IgA antibodies in the nasal passages, I would think it's possible for a person to carry COVID around until the other antibodies came into play.

The way I'm understanding it, IgA responses lessen over time:

Neutralizing and binding antibody kinetics of COVID-19 patients during hospital and convalescent phases

So, after about 6 months, the host's response to COVID would require humoral immunity (which would then trigger production of IgA antibodies to COVID. Is there a brief period, then, when a person could still transmit COVID?

I watched a couple of doctors discuss this somewhere (I can't remember where, I think it was a university channel on youtube) and they said it is unknown whether the vaccine OR regular immunity gives "sterilizing immunity," which is what we're talking about. Right now, all the evidence is about "neutralizing immunity," in which the body's antibodies step up and defeat COVID. Apparently some vaccines (polio, IIRC) provide sterilizing immunity, but others do not (and these doctors said there's no way to predict, so the research has still be done).

Keep in mind that the vaccine provides recipients with greater amounts of antibodies, which should result in a robust humoral response and a longer period of other active immunity.

It does seem possible that people could "get COVID twice" and there's some chance they could still transmit it (we just don't know) even if they are themselves immune and experience no symptoms (that's the case if we just have neutralizing antibodies and not a sterilizing system).

Since no one knows the answer to this, any medical professional is obviously going to say we should all still wear masks.

I've never heard of dyes in vaccines, nor do I see a sulfite in this list... here ya go..

I posted this a few days ago, and this has what you are asking for. COVID not approved yet, although may give you a potential idea of possibilities? Since mRNA are new... I'm not sure there is a comparison on this list.

"I was down a rabbit hole for something else and found this. Of interest, what are the "other" ingredients in vaccines. Each vaccine in the US is listed. Just found it interesting to add to the knowledge here and had to look up the 4 that I've gotten in recent years (flu, shingrex, MMR, pneumonia)

COVID-19 and MIS-C: Two Diseases, One Virus in Kids
— Both clinical profiles and even outcomes varied, researcher says

Nov. 17, 2020

“Pediatric patients with acute COVID-19 and those with multi-system inflammatory syndrome in children (MIS-C) had evidence of acute liver injury, but each group had different clinical features, a researcher said.

MIS-C patients were younger, had more ICU admissions, and higher levels of inflammatory markers, while COVID-19 patients with acute liver injury were more likely to have higher BMI
, reported Amanda Cantor, MD, of Columbia University in New York City.

In fact, BMI was significantly associated with degree of liver injury among kids with COVID-19, but not MIS-C, she said in a presentation at theAmerican Association for the Study of Liver Diseases virtual meeting.

Cantor described how there were "two distinct clinical phenotypes caused by the same virus." She and her colleagues added that MIS-C "changed the perception of the severity of this infection in children," as pediatric manifestations of COVID-19 in children were thought to be mild.“


Now, keep in mind, this is just one hospital, and as seen in the above quoted post, this is not the only hospital to say they are seeing more and more patients:

“While the CDC classifies MIS-C as rare, the doctors treating Vivian told her family they're seeing a kid a week show up with symptoms.“

MIS-C in Atlanta child who had COVID-19 | wtsp.com


News 8: What’s it like treating these patients?
McGee: I’d rather not have to do it. These are children that can get very, very sick and as I’ve said before some of these kids can die. This virus is real. This virus is dangerous. It doesn’t matter whether you’re a child or an adult. So, we all have to be careful to make sure we don’t get it because your child could be the one that suffers from a major consequence.“


Re: Here is another reason why I think it’s possible we are not seeing the full spectrum here:

“Nelson Delacruz, an epidemiologist for the state, confirmed the hospital’s cases had been reported. But while public health investigators counted them toward Virginia’s COVID-19 cases, they did not for MIS-C.

That’s because the department did not consider them to meet the U.S. Centers for Disease Control and Prevention’s narrow definition for the syndrome.
Delacruz could not elaborate on how the cases differed.“



CDC:

“Clinical Presentation
Patients with MIS-C usually present with persistent fever, abdominal pain, vomiting, diarrhea, skin rash, mucocutaneous lesions and, in severe cases, with hypotension and shock. They have elevated laboratory markers of inflammation (e.g., CRP, ferritin), and in a majority of patients laboratory markers of damage to the heart (e.g., troponin; B-type natriuretic peptide (BNP) or proBNP). Some patients develop myocarditis, cardiac dysfunction, and acute kidney injury. Not all children will have the same signs and symptoms, and some children may have symptoms not listed here. MIS-C may begin weeks after a child is infected with SARS-CoV-2. The child may have been infected from an asymptomatic contact and, in some cases, the child and their caregivers may not even know they had been infected.”

Multisystem Inflammatory Syndrome in Children (MIS-C)



ETA: My final assessment after posts above indicate that IMO, as a result of MASSIVE family travel and gatherings over Thanksgiving, as well as an already severely escalated Covid situation, there is very likely IMO going to be a surge of children, and babies, who will get very ill, have potential long term effects, and some (more) will die. Again, this is not something we are seeing a lot of talk about (yet), but wait for it, imo. This is very upsetting, especially considering much will occur due to disinformation and outright disregard, which could have been prevented.

Yesterday I mentioned the guilt that some may later feel for infecting their family members as a result of Thanksgiving travel - well, I now revise this to include guilt over their children who, as seen above, could become sick and die as a result - “rare” or not. Again, what does one consider “rare” - there comes a point where even a small percentage results in a large number when there is this much community spread. IMO, with increasing cases, this will become “not as rare” as previously described, simply due to increased spread/prevalence, jmo.

Ya know Margarita.... it is hard to keep up with ALLLL that you find, read and discuss. But it would be so hard, without ya, to be as informed as we are.

I so hope that you are wrong about the MIS-C and more and more children getting the more severe symptoms.... but I, too, really do want to stay on top of this as we go into these next weeks.. ....

I think we all should be sharing this info on kids and Covid... I am now.

We really do need you!!!!

From your hibernating friend, in Floridah...
