Given that it’s airborne chances are through breathing in proximity with someone who is currently contagious (and possibly asymptomatic).

Non-huge indoor spaces, absence of masks, breathing the same air for longer than 15-20 min all increase infection rates.

Not OP.

It's even worse than that, my dad got it in an indoor space (office) while both he and the carrier were wearing masks. Then I got it from him in the house, even though I avoided him and kept my distance.

He wouldn't wear a mask in the house (because "I'm fine") and kept coughing up the place, though.

You need to be very very clear about the type of mask you are wearing.

I wear an N95 or KF94 - I like the ones with the valve / vents so do a surgical over that if I use one of those.

I've got friends in covid care who had pretty high exposure with a good N95 and face shield without being infected.

So when people say they were masked up and got infected, you need to ask, was this just some fleece cloth or a mask designed for infection control.

I think it’s safe to presume that it’s a non-sealing, cloth mask as that’s what 99% of us “civilians” are using.

Even these slow down transmission so it’s a function of having a mask, time spent together, flow/amount of air, proximity.

The outlier being Austria where everyone is required to wear FFP2 (N95 equivalent) masks when indoors (shopping, public transport, etc). And the government mandated the price of masks to be less than 1 Euro each. Not to say they are handling things great, but that was at least one step in the right direction.
