My mother has recently been diagnosed with a Staph infection. She had surgery in January and a small area of the incision now has Staph aureus on culture. She has already been on antibiotics for 1 week and the wound has improved - redness and drainage has subsided. What are the chances she would develop TSS at this point? She is planning on leaving for a week long cruise on Saturday and has been advised not to go because she could get sick .
