and she took her mask off in the lavatory because . . . ????!!! A small confined space with I think no ventilation.

My impression from reports of the study is that the authors conclude the infection was most likely from aerosols, not surfaces. They probably inquired about hand washing in the lavatory. And if the infection had been transmitted via a surface, maybe another passenger would have turned positive as well. But unclear--did the infected transmitter create aerosols despite wearing a mask? Or did that person take his or her mask off in the lavatory too?

Still, effectiveness of masks again demonstrated, despite middle seats being occupied.
