I have often wondered about odors that are super strong, just filling the air of the room of 2 patients...one with diarrhea and the other without...and the staff that go in and out of these rooms inhaling these partially probably ignitable fumes from the bowels or urinary tract or even lungs from a patient.....my question is....IF YOU CAN SMELL IT...does this mean that those bacteria/germs/etc are floating in the air just like viruses? I tell my aides to wear double masks as well as for myself....I don't like anyone breathing in this foul stench ...you just don't know about certain things...if you can smell certain pollutions in the air, exhausts, chemicals, whatever....they can eventually harm you... I feel the same about C Diff, and any other odors I come across in the Nursing home.
