A few other things to think twice about.
Professional massages. MRSA can live on surfaces for months. If you are going to get a massage I would ask the parlor owners how they are
cleaning the surfaces that multiple people come in contact with.
Pedicures and manicures. Since MRSA spreads from skin to skin contact, pedicures and manicures are a very easy way to get the infection. Make sure you know what sterilization techniques are being used at the salon you visit. See if they are using an autoclave.
Showers and saunas. Showers and saunas that are used by multiple people are ideal places for MRSA to thrive. Opening your pores at these places might not be the best idea.
Public transportation. Since MRSA can stay on surfaces for months, it's a good bet that you could pick it up from taking the bus or a taxi. I am not advocating being overly paranoid, but I would say you should be conscious about not rubbing your eyes when using public transportation, and to make sure to wash your hands as soon as you reach your destination.
Sex. The definition of safe sex has now changed. Since MRSA can be picked up from skin contact, many people who were enabled to be more promiscuous through the use of condoms were the first to pick up staph infections. Showers before and after sex are definitely a great idea here.
