 [ Symptoms ] my friend found out she has mrsa from a nose swab we have had sex should i get tested [ Disease ] unless you have a skin infection that is consistent with mrsa there is really nothing to test mrsa is carried by 2 out of every 100 people regular staph is carried by 1 out of every 3 people just because it was in her nose does not mean she is infected just a carrier you should not be worried
