Not sure you can call it limiting the spread. We slow the spread. Which potentially prevents overrunning our hospital.

It seems like eventually everyone is going to get it. Slowing the spread also deepens the chain of infections and may lead to more mutation.

That's comparing apples and oranges because you're comparing the effectiveness of a particular treatment (condoms) with the effectiveness of a particular policy (mask mandates).

According to this study by the University of Cambridge, FFP3 masks provided "31-100% protection (and most likely 100%)": https://www.authorea.com/users/421653/articles/527590-ffp3-r... (preprint).

Face mask policies on a community level.

Not with trained healthcare workers.

What studies?

Do you need a study to understand that a latex condom can catch infected seminal fluids while a cloth mask cannot stop the spread of droplets, or aerosols containing covid?

A cloth mask does reduce the spread of aerlsols as well as droplets. Anything telling you otherwise is false and i will happily bury you in a dozen backing studies.

No it doesn't. The last year and a half is proof that masks played no significant role in reduction of infections. Bringing all kinds of studies doesn't prove anything since we effectively had the chance to witnesss the biggest study of all. Sure, it might stop some droplets. But a mask can never be as effective as a condom in stopping the virus. It s common sense. You can still infect or get infected. And that s the issue.

It's clear masks stop droplets. That's not in question. It's clear masks work for healthcare workers who are trained in their use.

But is wearing a filthy rag until the waiter brings the breadsticks an effective community mask policy?

yes
