Yes. If you have mrsa in your nose. You have mrsa. We all have staph on our skin and especially in our nose. The only way to really catch it as I have it myself is to have an open sore from her touch an open sore from you. I have it in my blood now. It started in my nose. Still the same do not touch any sores and have her get a perscription of bactoban nasal or muciprocin to put in and under her nose. This has helped many people. And will help it not to spread onto her.
