Two years were in the US, wearing good quality disposable masks designed to catch droplets. (They weren’t paper. More
Iike special non-woven fabrics.) One year was in Africa, where our sponges were made of the same absorbable, multi-layer cotton fabric as laparotomy sponges. These were laundered, boiled, dried in the sun, and reused. There were no N-95 masks yet. I like to believe those masks served a purpose and prevented the spreading of micro-organisms. They were required. When they were invented, their use cut infections. When I arrived in Africa, my OR had a 50% surgical infection rate. When I left, it was 2%. Required sterile technique works. Properly worn, high quality masks do filter out organisms, each way. I know of a study in the UK based on surgeries done without masks that says they don’t stop the spread of infection in the OR, but I’d like corroboration of that, and I still don’t want people coughing in my face.

OR masks are not designed to protect anyone from viruses. It's BACTERIA, which are exponentially larger than viruses...

You're comparing apples to kumquats...
