How do I prevent someone from dying of the black plague?

My dear sister Lady Agatha Beatrix Lytelfinger the III of Cornwall hath been affected by thy wicked plague and she lay in her chamber as her time slowly ticks to death. Hath we try and bloodlet her sickness away, it only made her body weaker. Because of being bedridden, she hath been sinful of sloth and we will be inviting thy Catholic Priest over tomorrow to perform an exorcism on her. To assure ourselves that she will not succumb to thy seocnes within the passing of these hours, we will need an efficient practice on her to cure her from thy flu so she will not die. Sha'll we try trepanning?

This is my beautiful sister as we speaketh.
