Interesting modelling study for schools: (theoretically) most effective is open windows, then masks, then HEPA filter. Would be good to do real world tests though. https://t.co/MDFNqNNUI3 pic.twitter.com/xGSodClipO

This is not real evidence supporting real policy choices as they are really carried out in the real world.

Instead, this is theoretical bioplausibility spun into a full paper.

I hope folks can still tell the two aparthttps://t.co/znwtiaKZ2g
