No, not if you think you may have MRSA or Staph. They are highly contagious. I actually have staph as we speak. I picked it up about 5 days ago, it's on my scalp and in my right nostril.
MRSA can be really bad. MRSA ain't no joke! My GF had that, ended up in the ER, on iv antibiotics, whent into pneumonia, almost died a couple of times. There are no longer any effective antibiotics for new strains of MRSA. You just pray you have a strong enough immune system to fight it.
