I had to be tested for Mrsa prior to my surgery, to see if I was a carrier. They told me that even though you may not have it, you could be a carrier. My surgery was in Cincinnati, Ohio. However, I do have a brother that was working in a hospital installing some equipment and he contracted Mrsa while there. So you can never be to sure. I'd definitely make sure anyone who comes into contact with you washes right there in front of you. That is what I did. Even my husband and daughters.
