What does bailey have that is making her patients die on Grey's anatomy?

they're not dying i think they're just getting post-op infections, right? but i might be wrong. anyway who knows i guess we have to watch to find out. maybe there's a twist and it's not Bailey after all and it's one of the nurses who always works with her or the guy/lady in charge of cleaning the instruments doesn't do a good job or something like that. who knows but the show is getting good! i dont like how they were all mean to her though at the end of the last episode they could have been more sympathetic even though the own the hospital and whatnot, they are her friends!

I know this one I think its linonophobia ( morbid fear of string ) but you could always ask Dr. Medicine about getting a seeing eye bear.
