You can get Hibiclens at any drugstore, like CVS, and a topical antibiotic cream for the nostrils is what is recommended.
Also, oddly, the less history you have of using antibiotics in the past, the stronger your own defenses are to fight MRSA, which is why so may elderly and those with compromised immunity have such virulent cases.
And persons with AIDS/HIV. NYC had an epidemic in the queer community awhile back. Posted on FR, iirc.
Bactraban is what they use at the Dialysis Center for your nose.
