Can I get bell's palsy from my sister?

[TaylorFan1513]

My sister just came home and she has bell's palsy. I want to know if I can get it from sharing a bathroom with her. There only other bathroom on this floor she has already use. Is there any way I can not get it? I really don't want to get it. She is 24 and I am 15 and school is coming up. I don't want to go back to school and be teased if I get it.

Help!
