If you have a MRSA infection can you always have mrsa?

CARRIER STATUS. You can be a carrier, but this can also be treated. It is usually harbored in the nose, and intranasal treatment with Mupirocin ointment (bactroban) can help get rid of it.
Yes. Mrsa has found an environment that is hospitable enough for it to colonize the skin and other parts of the body. Though this may sound horrific, one should really just embrace the fact that MRSA is here to stay, and requires vigilance on one's part to clean cuts immediately, avoid sharing personal clothing/towels/razors, washing hands, and practicing excellent hygiene.
