And as for talk of transmission vectors: There are two known primary mechanisms of covid transmission.

The first is direct transmission: short range, effectively line of sight person to person transmission via large droplets that are too large to aerosolize. This is the primary mechanism of outdoor spread, and can largely be eliminated by mediocre masks worn correctly.

The second is aerosolized transmission: potentially longer range, sticking around in air for multiple hours. The key here is ventilation and volume: a proper ventilation system can slowly remove covid particles from an enclosed space, either through venting air or properly maintained HEPA filters. Likewise, larger places with good interior airflow and movement of people are better, as it prevents airborne covid particles from building up enough density anywhere enough to cause infection. Masks can help with this, but you're going to want a well fitted N95 mask. These can filter covid quite effectively, so long as the fit keeps the air moving through the mask instead of via holes around the sides. If worn properly an N95 will drop your odds of getting a covid infection to 25% of what it would otherwise be, and also reduce odds of you spreading it to others to 1/6 your original odds. Notably, if everyone in a room is wearing N95s properly, this means the odds of it spreading are about 4% of what they would otherwise be. Cloth masks are useless against this transmission vector, and basic disposable surgical masks are mediocre. This btw is why everyone kept getting covid after taking their 90% effective first covid vaccine and deciding it was okay to remove their 90% effective masks :P Gotta do both if you actually don't want covid.

As for surface transmission, a big deal was made about it early on before they knew a little of the basics about the spread of the virus and speculated it would be relevant. It was not. Despite searching the topic for years, I have yet to see a single source suggesting even a single case study of transmission occurring outside a (much higher risk) hospital situation which was determined to be caused by surface contamination.

Anecdotally: I always wear an N99 (barring when eating or drinking) and I've not had covid once.  Fwiw

I got both Swine Flu and Avian Flu the first time they came around. 0/10, do not recommend.

It finally happened, I finally caught covid. Ducked it for three goddamn years.

Probably after sharing a train with people for forty hours, since our primary engine, backup engine, and backup backup engine all failed in stupid fashion. Do Amish people still have vaccine hesitancy? There were a lot on the train...

Good thing I work remotely, but it's still going to be a pain in the ass to muddle through work today...

RE Swine Flu: Yeah, it sucked. I caught it and it sucked. 40% of my high school class caught it and were out sick for a week there. Would avoid in the future.

Large droplets survive longer, with payload, to settle on surfaces (including faces) for further contact transmission.

COVID hasn't been shown to readily transmit from surfaces. (This article claims risk 1000 times less than airborne.) The overwhelming majority of cases are from poorly ventilated places where airborne particles saturate to the point where you're constantly breathing them in. Large droplets can't do that, since they quickly fall to the floor.

When working I talk to people at close range. Plus even if what you are saying is true, crying wolf and all that for past several years, +1million death toll etc. I'll just wear a mask when the covid map isn't green in my spot, it's easy for me. I'm sorry if it's not for you.

Didn't even know they made an "N-99."

N, R, and P 99 all seem to be about the same thing; 99% minimum efficiency respirators. There's a 100 tier, too, that's 99.97% efficient. Mostly seems to be getting up to the point there's active filters of some sort or another going on, they seem to generally have the lil' insert thingummies on 'em. They're apparently notably less comfortable than a n95, and largely overkill for general use to boot.

But how does a military gas mask rate when compared to a N95?

Are there any reuseable n95ers? I just did a glancing cost check and they seem to be sold in the price range of 10-30 Crowns per mask ($1-3) here, and 20 crowns per day isn't a negligible reoccurrent cost.

The bird flu reached the lakes around my area. Killed a nesting couple of swans and the duck herds have thinned greatly, though otherwise the geese and swan population at large appears very robust

None of you seem to understand . The geese are not trapped out there with the bird flu. The bird flu is trapped out there with them.

Most of them I've noticed are noted as being reusable at least four or five times before it starts being a concern, iirc, especially if you let them air out for a day or two between uses.

You might want to be extra careful if you've been in a particularly high risk environment (i.e. inside a hospital or whatever), but for day to day use some reuse seems to be okay.

For real, the geese actually seem happier now a lot of the aggressive swans are dead

The geese want you to think the bird flu killed the swans, but in reality the geese killed the swans.
