My sister-in-law was in ICU for 2 weeks with this infection, and then went to a convalescent facility for a week. She is now home, but my brother is beginning to show symptoms - diarrhea, cramping, low grade fever. They are both in their 70's and have a myriad of other medical issues. They are both pretty much homebound, so how could they have gotten this? Neither of them was on antibiotics prior to the onset of symptoms. We have hired a sitter to be with them to help. I'm also concerned that she might be exposed. I'm very concerned. Any information the DC Family can give me will be very appreciated.
