. @BristolUniversi& #39;s policy is scientifically illiterate. Should be the other way around: masks even if one can maintain 2m distance, to protect against aerosol transmission. Visors in addition, to protect against droplets if one can& #39;t maintain 2m distancing. ( @Bristol_UCU)

I hear that KCL is also recommending visors, not masks. I wonder whether, therefore, this is on advice of the @RussellGroup.

I see that, a day or two after I posted my tweet at the top of this thread, Bristol changed their policy so that now masks (as well as visors) are required in the classroom.
