I definitely went through a range of emotions from confusion to anger that more wasn't done to minimize the likelihood of incidents like this.
As I learned more, I realized how improbable this situation was in the first place. My current understanding is that while our* probability is higher than the average American, we're still highly unlikely to develop CJD. More importantly to me is that there isn't anything I can do about it, so I try not to let it consume a lot of my mental energy.
*I think there was a two week window, so anyone operated on at that hospital during that window is in the same situation.
