There is no doubt about it.  I think the key point is they may be less likely to be symptomatic and less likely to be tested.  Those are conjecture based on numbers in my health system so it might be limited by the fact that it only has data from 3 states.

The statement “kids do not pass the virus to adults” is misleading.  The correct statement is that they are not the primary source of infections and are a less likely source.  “Do not” would men zero infections.  I have plent of positibe clusters to prove it.  Just so you know, I am one of the planners for the Southern USA.  I am the one that oversaw the ramp up testing and treatment.    

And masks do not stop the spread of covid.

That is why I said children are not a main driver.  They simply are not a cause to worry about.

The best part about a posted, peer reviewed, scientific study is that all the data and methodology used is easily available. 

Rather than claim your anecdotal evidence is the actual truth, respond to the study and show where they are wrong.  Just know that anecdotal evidence will always lose when put against direct evidence, so you will need far better support to show what is already scientifically accepted as correct is actually wrong.

That is how science works.  Just saying "I claim it is not true, so it is not true" is meaningless.

Show them wrong by rebuttung their study, science is designed this way on purpose.  It is a good system.

When you do, post the link here so we can read it.  I look forward to reading the scientific rebuttle you provide.  Until then, the peer reviewed and direct data supported study stands as correct.

What is your source for the 64% immunity in children? I'm finding plenty of material on the lower impact of the disease on children, but nothing stating so high a number are outright immune, nor anything indicating that they are not capable of transmitting the disease.

The link is near the top of this article, it takes you to a preliminary PDF of the actual study, since Nature Magazine is a for pay magazine.

https://www.technologynetworks.com/immunology/news/common-cold-coronaviruses-could-help-produce-anti-sars-cov-2-immune-cells-337504

Basically, the common cold is made up of several coronaviruses and other virus types. Some of these create antibodies that also protect against covid19 in a greater or lesser degree based on the age of the person.

The immune systems of children are far more powerful than adults, giving them a full on immunity instead of only making covid19 a hassle, as it does in adults who have the same antibodies. This is part of the reason why most people who get the virus have such minor symptoms.  Genetics are another factor. 

 

The reason they do not pass it on is the viral load never gets high enough to transmit the virus.  Their immune system crushes it so very quickly. 

I suspect almost no one understands the common cold is made up of rhinoviruses, coronaviruses. RSV, and parainfluenza viruses.  If they did, the number of people in terror over covid19 would be reduced.  Respect it, yes, live in fear, no.

The link is near the top of this article, it takes you to a preliminary PDF of the actual study, since Nature Magazine is a for pay magazine.

The actual study is available here (Nature) and referenced here (NIH PubMed).

[...] Basically, the common cold is made up of several coronaviruses and other virus types. Some of these create antibodies that also protect against covid19 in a greater or lesser degree based on the age of the person.

That's not what the article says. The article actually says:

From the study published in Nature: SARS-CoV-2 belongs to the Coronaviridae, a family of large RNA viruses that infect many animal species. Six other coronaviruses are known to infect humans. Four of them are endemically transmitted8 and cause the common cold (OC43, HKU1, 229E and NL63), while SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV) have caused epidemics of severe pneumonia9

The viruses associated with the common cold are 4 members of a larger family of viruses that also includes other coronaviruses including the outbreaks referred to as MERS and COVID-19. COVID-19  is not caused by one of those 4 viruses, but is a member of a larger group of viruses. It is a "relative" if you like, much like a cat and a tiger are both felines but not the same thing.

From the study published in Nature: Next, we showed that patients (n = 23) who recovered from SARS (the disease associated with SARS-CoV infection) possess long-lasting memory T cells that are reactive to the N protein of SARS-CoV 17 years after the outbreak of SARS in 2003; these T cells displayed robust cross-reactivity to the N protein of SARS-CoV-2. We also detected SARS-CoV-2-specific T cells in individuals with no history of SARS, COVID-19 or contact with individuals who had SARS and/or COVID-19 (n = 37). SARS-CoV-2-specific T cells in uninfected donors exhibited a different pattern of immunodominance, and frequently targeted NSP7 and NSP13 as well as the N protein.

The article is noting that people who have not directly been exposed to COVID-19 can have some resistance, possibly due exposure to other members of that family of viruses. 

The immune systems of children are far more powerful than adults, giving them a full on immunity instead of only making covid19 a hassle, as it does in adults who have the same antibodies. This is part of the reason why most people who get the virus have such minor symptoms.  Genetics are another factor. 

I searched the peer-reviewed article and am finding no occurence of the words "child" or "children". The word "school" only appears in references. I do not see any reference to 64% or actual immunity, only the presence of T-cells in the population at large.

The reason they do not pass it on is the viral load never gets high enough to transmit the virus.  Their immune system crushes it so very quickly. 

That is not stated in the article. The speculation that Common Cold” Coronaviruses Could Help Produce Anti-SARS-CoV-2 Immune Cells is a headline from technologynetworks.com. That article states:

From the technologynetworks.com article: It’s important to consider that the presence of T cells that can react to a peptide of SARS-CoV-2 in a person’s bloodstream doesn’t necessarily mean that they are protected against COVID-19.

This emphasizes that these findings don't imply that a population is immune, merely that they have T cells present that can react to the COVID-19 virus.

I suspect almost no one understands the common cold is made up of rhinoviruses, coronaviruses. RSV, and parainfluenza viruses.  If they did, the number of people in terror over covid19 would be reduced.  Respect it, yes, live in fear, no.

As the study cited in Nature clearly states, the common cold is associated with 4 viruses that are in the same family of coronaviruses as those that cause MERS and COVID-19. They are distinct and different in many ways, including mortality and transmissibility. MERS and COVID-19 are not merely flavors of colds. The viruses are related but different in many ways.

True.  Coronaviruses actually make up a small portion of common cold virus.  

Viruses that cause the Common Cold:

  • Rhinoviruses: 20-40%
  • Adenoviruses: 10-20%
  • Coronaviruses: 10-20%
  • Respiratory syncytial virus: 10%
  • Parainfluenza Virus 10%
  • Influenza A and B have very similar symptoms in healthy humans.  It either bowls you over or is mild like a cold.

I find human physiology amazing.  We know so much, and yet we still know so very little about ourselves.

The best reason to wear a shield combined with the mask is to avoid touching one's face with contaminated hands.

I had not thought if thay, excellent idea. 

AOC could use that, while saying not to touch your face, she touched her own close to a dozen times.

I concur.  The face shield has multiple avenues of protection.  

I got the vaccine, Moderna, on 23 December.  I become very ill on the 28th.  I am positive for COVID.  I am 100% certain I caught it waiting in line for the immunization.  No starts my mandatory downtime.

That is valid but debatable considering the eyes are one location to catch aerosolized virus.

Chuck, sorry to hear you've tested positive. Take care of yourself and those you hold close. Touch base when you can.

I can trust only the N-95 even though I'm not that paranoid about Covid. These regular ones you get from the pharmacy, sorry but they're shit nothing else

N-95 or 3M repirator are all I will use in the ICU.  I caught COVID treating patients.  I am surprise it will me nearly 10 months to catch it.

Thanks.  I am 90% back.   I had both vaccines also.  They kicked my butt twice.  

I really hope this ends soon.  I have lost a lot of patients.  I have treated hundreds and my success rate is over 80% in ICU patients.

Me too, my Aunt passed away last month victim of this scourge, she refused to be placed on a ventilator reserving it for someone who'd live longer. We'll miss her the next time we visit the States.

I'm really glad to hear that you are almost over your fight.

I've never been tested but early on I had cold symptoms with loss of taste and smell and some lesions on my hands and feet. This following a visit to the ER with my mother in law late February last year.

A few months following that I had a few weeks where my thyroid gland albeit shut down.

In the next months I suppose that I'll get the vaccine, slow rolling in Europe. If I was there in the States perhaps it would be sooner.

Keep getting better! 

Stay safe and healthy, Phil...
