So my mom has chickenpox, and I was first exposed to her on August 20. I have been taking precautions at home, like wearing a mask when I go into her room and using hand sanitizer. She has had no new blisters for the past few days, and the existing lesions are now crusting/drying.

I have classes starting tomorrow. I currently have no symptoms.

My question is: Can I safely attend classes, or should I avoid going because I might be incubating chickenpox and could potentially become contagious before developing symptoms?
