Hiring a nurse that's a carrier of MRSA - Can that happen?

My better half is getting over an outbreak of MRSA. He is a nurse and works in surgery. We think he contracted through a patient who came through the OR two days prior. He's been in the hospital for almost a week, and had I&D for an abscess that developed a week ago. I went to our family dr to get my nose swabbed for MRSA, if I am a carrier or colonize it. I am thoroughly distraught over this whole event and worried about his health, my health and his job. Can they fire him for contracting MRSA? I have been reading everything possible on this nasty bacteria and would appreciate further insights from you all......
