VRE stands for Vancomycin resistant E.coli and MRSA stands for Methicillin resistant Staphylococcus aureus. Both of Staphylococcus aureus and E.coli are normal inhabitants of our body and ALL of us are always carrying these bacteria. If tested in persons who do not have the disease, many of us will test positive for such bacteria. But still there is not much to worry about. In specific situations, when these enter our blood stream, they become pathological. There are all sorts of antibiotic sensitivity and resistance traits in a bacteriological pool. Out of that, on occasion, one strain gets identified. Once treated properly, the person would be cured of the infection and there is no need to think that he is a carrier. If a person has already been treated for the infection, there should be no issues with living in a multi bedded boaring facility and I do not think that the state licensing board will have any issues with the same. The simple precaution to maintain is proper health and hygeine issues that you have to maintain anyway. Not using anyone s usables would be recommended. Nothing more specific. I do not think that isolation is required if the infection has already been treated.
