Oh my. I just brought my Mom home from the hospital on Sunday after a 3 day stay. It was discovered that it was C Diff. I had no clue what it was and now I know way more than I wanted to! Spent Sunday night santizing her 3 bathrooms.
What a nasty bug. Her's was from another medication that she'd taken for a long time. The MD surmised that it changed the acidity level in her gut, allowing the C Diff spores to "bloom". She is taking heavy duty antibiotics and is feeling quite good now.
She too had recently had a UTI, I was schooled by the nurses that seniors can harbor these infections and they "just can happen". Aging is not for the faint of heart!
Hope your Father is doing well and I am keeping fingers crossed that he comes out healthy and feeling good!
