I read a US article today (CDC or some other official body) that said for Omicron, you need an N95 or KN95. Cloth masks just don't cut it.

I was wrong about the source of the study, but here is the complete article from NPR.

www.npr.org

With omicron, you need a mask that means business

To block a variant this transmissible, scientists say you need an N95 or other high-filtration mask. Here's how to find a good one and when to wear it.

Just to confirm, this post is meant to be humorous so no hate mail please :nailbiting:


For any or all information on masks, we need go no further than the World's highest paid Health/Science adviser on all things Covid related.

Dare I mention he has/is making a motza from Vaccine sales via his NIAID agency

The dis-honorable habitually lying, and generally naughty boy: I give you

Mr Anthony Fauci :shifty:


Trust me. My name is Fauci

There's been recommendations of wearing multiple masks. But unless you follow all the protocols on masks and disposal then you can actually increase infection.
Almost everyone just throws them in their car and wears them for days or weeks on end.

N95 were the only things that really lessened it in the past with delta/covid.

It's basically a public "feel good" measure if it's masks alone. But it captures when people cough,sneeze, or yell.

But everyone is getting omicron masks or not.

I think Sydney is going to surge with case numbers shortly, the clinic mix up giving out wrong test results will have a huge impact.

Having said that, Omicron isn't nearly as deadly as Delta.

I cant believe it when I see the queues over East on tv, it must be a family day out for some, "come on kids get the thermos and the picnic hamper, we're off for a test".
 
Sons gone to get tested as he has tested positive on the rapid testing twice. He has flu symptoms. So at least two of them have it. I'll test on the rapid test to see if I won the lurgi Lotto.

Lucky I've been lazing round the house the last few days.
 
Haven't seen to many discussions re masks that are any where near the mark and usually end up on some ideological rabbit hole or about discomfit.

All masks work to a degree its not a binary situation.

Its about the materials, face fit, face shape, beards etc, fit for purpose, at what point overload / saturation occurs, mitigation strategies and much more.

Pretty much all the masks / respirators I used in industry failed at some point even the escape respirators, have seen many lung injuries as a result but they also saved lives.

In a industrial setting the protection is for the wearer, in a medical setting its actually both ways and as the level of protection falls generally ends up for the purpose of others not the wearer.

Even in a full face SCBA with sealed suit you get failures particularly getting out of the gear, contamination / infection control is still difficult.

Even poor materials or badly fitting quality masks still provide some level of protection its not a binary argument.

Watching the testing people in those drive through stations often the masks are not worn correctly (fitted) yet they still provide protection combined with the face shields.

Poor masks provides next to zero protection or increases risk. They stop you spreading it though.

Viruses can just pass through as masks will stop down to a certain size particle.

Indoors and in crowded numbers and you are not stopping it.
Outdoors which is where they do the testing and it reduces the risk by a large margin. Hence why testing is normally done Outdoors.
Being outdoors and distancing is enough

Kitty Flanagan's "More rules for life" best selling book is very funny on masks. Specially the bit on letters saying you don't have to wear them.

The point is pretty much all masks leak they don't totally stop particles, gases or pathogens and can be a source of infection or contamination but they still do a job.

Early in the COVID out break doctors and nurses were leading in the death rate largely due poor or lack of PPE leading to their continued exposure to higher viral loads hence suffering higher levels of disease which came out in the death rates.

There are similar studies regarding the flu.

Wearing a mask, any mask will reduce the viral load whether either breathing or exhaling safe to assume that translates to a degree if you contract or the level of disease you might suffer.

Like many of the issues surrounding COVID there are no certainties and a lot of grey but there are absolute probabilities.

Some actually provide that little protection
It can also stick to your cheapesht mask and increase risk.

It's actually dangerous to say certain types of masks offer any sort of protection.
They protect everyone if everyone is wearing one and following rules. And they do that by capturing aerosols not by blocking.

As a mechanical engineer with a background in aerosol science, I often wondered why months into the pandemic we were still using cloth masks. People used similar coverings during the Spanish flu pandemic in 1919, more than 100 years ago. I knew better mask technology existed, and people needed to know about it.

So I embarked on a year-long mission to test, document, and review the best masks I could find. This eventually entailed building a mini aerosol laboratory in my bathroom, with scientific instruments capable of measuring particles 1/50,000th the width of a human hair. I have a public database for my results. And a Youtube channel. Over time I began to be known as the Mask Nerd.

... Aside from helping individuals choose the best mask for themselves, I would also encourage governments to increase the domestic production of masks, which would not only create jobs, but also allow regulatory oversight and a supply of effective, safe masks for their citizens. And good masks should be provided free of charge to the many that may not be able to afford them.

Not all masks are created equal, so it’s time to make sure everyone knows about high-filtration masks. These simple, inexpensive and super-effective masks can make a significant difference in our fight against Covid. If you wear a mask, you might as well make it count by wearing the best.

Omicron in Newcastle, I know two young people (20s) from Argyle House vaccinated super spreader party.

Both feel lethargic, say it feels like a bad cold, both isolating in their bedroom of shared houses, all people in both houses are vaxed so they don't care if they get it (so they say)

Wait and see I guess

Update on this, one is good to go (4 days), the other still a bit iffy after 7 days (I wonder does she have Delta)

Thanks for the updates chaps.

Just wondering, have the folks tested positive been on any vitamin or medication regimen prior to or post infection? And if so, has it helped.

I still take my daily Quercetin/Zinc/D3/C .... fortunately no infection even though had close contact recently (lucky perhaps?)

Covid is basically a "clotting disease" so apparently plain old aspirin (if you contract covid) is helpful, but dyor of course.

Good luck with it.
