You are absolutely right! This woman is terrified and with good reason. If the TEACHER would wear a mask, at least the flying germs could be contained, no matter what sort of bacteria she was getting on everyone! It would ease the caregiver's mind about carrying the virus home. At the very least, it is RUDE of the teacher. No matter what she's spewing, nobody wants it on them! Has anyone spoken with the teacher? Of course, teachers know more than anyone else so she probably wouldn't listen...
