No it hasn't. Show me the research.

It's not an absurd contradiction. A member of the public walks around and is only going to meet a few people with covid-19, and hopefully they are pre-symptomatic (because if they have symptoms they need to stay at home)

A healthcare professional is stuck in a room with symptomatic people, often in close contact. And they're not wearing a cloth mask or fluid resistant surgical mask, they're wearing a mask that has to be fitted to them. They have training on how to put it on and take it off. They also wear gloves, a gown, and a face shield or eye protection. They have running water and soap, and they have alcohol handgel. For fluid resistant surgical masks they take them off and use a new one for each patient.

One patient in one ICU bay will have 30 pairs of gloves used by staff per day.

Here: https://www.livescience.com/face-masks-eye-protection-covid-...

> With face masks, the chance of infection or transmission was 3% with a mask compared with 17% without a mask, a reduction of more than 80%. And for eye protection, the chance of infection or transmission was 6% with protection and 16% without.
