Many of my coworkers have noticed the same problem I have noticed-- I can't get rid of this sinus infection.  I have been various stages of sick from a sinus infection since mid-December, and every time I kick it thanks to antibiotics, it comes back after a week or so of constantly wearing a mask. PLEASE make it personal choice to wear masks for teachers and END THE MASK MANDATE.  The CDC has said they don't actually do what we want them to do anyway, and at this point it is causing more harm than good, at least in my sphere.  Thank you for your time and attention to this.
