Needed for context, when talking about kids and immunology:

It is physically impossible to train the parts of the adaptive immune system that haven't developed yet.

They have to be there to activate.

This is not a fringe claim, vaccines are designed with this in mind:

The transient delay in IgG2 antibody production is clinically relevant in the context of vaccination, as this subclass is mainly responsible for the response to polysaccharide antigens.This fact explains why response to polysaccharide vaccines is impaired in children under 2 years https://pmc.ncbi.nlm.nih.gov/articles/PMC6817213/

So if someone tells you an infant under 2 needs to be exposed to pathogens, without being able to tell you which pathogens have polysaccharide envelopes and what that means in the context of infants acquiring immunity, be on guard

And some pathogens are harmful even if adaptive immunity is activated!

If that infant catches RSV (or EBV or SARS2 or influenza or multitudes of other airborne pathogens) there is a serious expected cost and no known advantage.

I am not an immunologist, if I've misunderstood please correct me.

Why is wearing an N95 so effective, and wearing a blue surgical mask not very effective? Physics!

There’s a significant difference between a mask and a respirator. A surgical mask is just fancy fabric that catches, well, spit. An N95 has an electrostatic charge that grabs particles and holds them. Think about rubbing a balloon on your head and watching your hair stick to it. That’s the science working to keep viruses out of your lungs when you breathe, instead of letting them waltz right in.

Parent: "The kids have been sick for weeks, they're probably not contagious any more."

Everyone else: "great!"

Me: "I'll just keep this :mastorespirator: on thanks."

Parent: "But how will you eat?"

Me: "I can manage without snacking, don't worry!"

(very few days later)

Them: "I feel so sick, I can't even imagine going for a walk around the block. Brutal!"

Me: "doing OK over here - get well soon!" (privately thanking the mercies that the respirator seal seems to have been good enough)

@skinnylatte first off this thread is a gold mine of people worth following - informed and unwilling to deny overwhelming evidence :mastothumbsup: :mastorespirator:

my answer varies by who's asking

as @foolishowl said kids are maybe the hardest. I'm mostly at "this stops me from getting sick" for kids.

friends and friendlies, I use the question as an excuse to info dump, which I follow up with an email with pull quotes and citations from reputable sources, so they know it's not BS

unknowns and hostiles get some variation of "I can't afford to get sick", "are you going to pay my bills if I get sick", and then info dump what I can

Already a measles outbreak in the Toronto Area, 2 days after kids went back to school Pls get the MMR vaxx & wear a mask for the best protection Respirator masks (especially N95s) protect against any airborne virus, including measles & COVID COVID cases are also ⬆️ #COVIDinformed #AirborneAware

Protected from airborne viruses while going for a walk & repping some of my faves 🤩 Outdoors is lower risk but not zero risk COVID 🦠 moves like smoke 💨 Protect yourself outside especially in crowded areas 😷 Surge will ⬆️ as kids are back at school #COVIDinformed #AirborneAware #KN95sSaveLives

A recent common cold may nearly halve risk of COVID-19, study suggests

So Covid-Competent folks - this is going to land different in different quarters.

• The previously evidence-supported paradigm/metaphor "the immune system is a candle not a muscle" might need to be abandoned for a third, more nuanced position[+]
• Of course there's the need to check the paper itself, and if it's solid, to replicate / validate, but beyond that.
• Folks with immune dysregulation can't all just catch rhinoviruses all the time to keep the system active.

[+] probably approximately: "microbes vary:

• some are overwhelmingly beneficial, eg. in our gut;
• some have mixed costs and benefits like rhinovirus or conditions when they become pathological like candida, and
• some basically only have costs like influenza(?), SARS1 and SARS2, measles"

in this week's COVID-19 roundup from @ducky includes highlights like:

paper from Germany found that 21% of masters’ athletes (median age in the high 50s) had Long COVID. The prevalence did not differ by sex, athletic specialties, training load, or prior competition level. Long COVID can happen to healthy, fit people!

(emphasis hers)

from market vendors who self medicated:
taking aspirin increased the risk of COVID-19 infection by 134%;
taking vitamin C decreased the risk of COVID-19 infection by 56%.
Meanwhile, not getting a 💉 COVID-19 booster increased their risk by 238%.

and

for immunocompromised people, taking Paxlovid for 10 or 15 days instead of five days didn’t make a whit of difference.

hey Covid-Competent, well-informed folks! I have a favour to ask!

has anyone bookmarked a good reference for what % of SARS-CoV-2 cases are due to fomite transmission?

the US CDC was at one point saying:

each contact with a contaminated surface has less than a 1 in 10,000 chance of causing an infection [1]

but that's not a % of infections, it's per contact with contaminated surface. That's supported a few ways, eg. by a sampling that included counting touchpoints:

The estimated risk of infection from touching a contaminated surface was low (less than 5 in 10,000) by quantitative microbial risk assessment [2]

but that study didn't actually culture virus, they checked RNA levels and counted touches (and again, is per contaminated touch, not per case)

Try as I might, I can't actually find a grounded estimate of how many actual infections have been fomite-driven at any point in the SARS-CoV-2 pandemic.

has anyone bookmarked a good reference for what % of SARS-CoV-2 cases are due to fomite transmission?

the US CDC was at one point saying:

each contact with a contaminated surface has less than a 1 in 10,000 chance of causing an infection [1]

but that's not a % of infections, it's per contact with contaminated surface. That's supported a few ways, eg. by a sampling that included counting touchpoints:

The estimated risk of infection from touching a contaminated surface was low (less than 5 in 10,000) by quantitative microbial risk assessment [2]

but that study didn't actually culture virus, they checked RNA levels and counted touches (and again, is per contaminated touch, not per case)

Try as I might, I can't actually find a grounded estimate of how many actual infections have been fomite-driven at any point in the SARS-CoV-2 pandemic.

hey Covid-Competent, well-informed folks! I have a favour to ask!

In 1987 volunteers were exposed to rhinovirus ("common cold") either by sharing air, or by sharing heavily contaminated objects.[2]

Most of the people who shared air with an infected person got sick.

None of the people who handled the heavily contaminated objects (and touched their faces!) got sick. And:

5/8 donor hands yielded culturable RV-A16 virus, while none of the recipient’s hands did [1]

Toronto has the 2nd worst air quality in the 🌎 due to wildfire smoke If you live anywhere near Ontario or Toronto, plz wear an N95 mask if u need to go out If not, turn on your HEPA air purifier(s) indoors as wildfire smoke can seep thru cracks / gaps in windows & doors #AirborneAware #CleanAir

HEPA air purifiers help too Wildfire smoke can seep through cracks or gaps in your windows & doors #N95sSaveLives #AirborneAware #WildfireSmoke #N95sWork

Ridiculous that when you’re pro-mask, some people are quick to say you’re anti-vaxx Most of us in the #COVIDinformed & #AirborneAware community have gotten multiple doses of the COVID vaccine (at least more than 3, but often more than that), the yearly flu shot + all the other recommended vaccines

Not going to reply to ridiculous posts anymore that waste my time Actual #COVIDinformed & #AirborneAware people wear a mask in public spaces because we know that a respirator mask (KN95 or better) is another layer that adds to protection from the most up to date vaccine (for ANY airborne virus)

COVID informed people ARE living our lives We’re just not behaving or making decisions like the government or the rest of society want us to They want us to 🙈🙉🙊 just like them #COVIDinformed #COVIDcompetent #AirborneAware

Imagine a faith that puts the well-being of people ahead of corporate interests in 2025.

THIS is what living a moral life can look like. Caring about others, refusing to perpetuate false narratives, protecting oneself, following evidence as it accumulates.

BONUS: THIS WEEK they're selling ultra-quiet air purifiers at a discount, to fundraise https://www.stmargaretscedarcottage.ca/order-your-air-cleaner.html

h/t a zero :mastomask: 👍
