This is supposed to be a right wing conspiracy sight

So you likely have antibodies?

did you read my OP?

Yes, for procedures, not casual contact.

Yes, I do.

Not going to answer? Not surprised.

These are the conclusions by a quack.

Such a quack that when Britt Hermes, who spent a lot of time and money learning that form of quackery came to realize that it is indeed quackery and spoke out about how quacky the quackery is that this quack sued to silence Hermes.

Chalk this up to a fail.

It would be easier.

Why do they bother?..Apparently, according to some, they don’t stop the spread of virus, or droplets from the nose or mouth.

Would anecdotal evidence of you not contracting it again as a result of wearing a mask apply?

i would suggest the mask makes you no more or less safe. but what i suggest is not based on science as i have done no studies.

For myself? No. My coworkers? Absolutely. My institution has an antibody rate of around 4.5 percent, compared to the general population of 7%+, despite us having 5 floors dedicated to covid patients.

what else do you do to protect yourself? just wear a mask or what?

I have goggles, a face shield and a protective smock that is disposed of once I leave the patients room.

Normally I don’t engage in debunking gibberish, but I scanned it and look what it says.

"In this meta-analysis, face masks were found to have no detectable effect against transmission of viral infections. (1) It found: “Compared to no masks, there was no reduction of influenza-like illness cases or influenza for masks in the general population, nor in healthcare workers.”

Yeah, guess what, that’s known that masks aren’t effective against influenza.

Guess what isn’t influenza? Coronavirus. Guess what is showing to be effective coronavirus? Masks.

This is why you don’t do motivated reasoning, or believe quacks.

If your glasses fog up while wearing a mask, you nor those around you are any safer by wearing a mask.

Interesting. Do go on.

That is not all it says, but still you have no studies of masks to present. are you a quack?

If doctors are wearing them to treat people in hospital pretty sure they work somewhat.

no vitamins or anything else?

Sure.

That means your breathing unfiltered air and exhaling the same.

Do you need me to explain what unfiltered means?
