epidemiologist interested in IC nursing

I'm currently a master's level epidemiologist with about 5 years experience, first doing outbreak investigations and original epidemiologic research with the CDC and now working in a community outreach department at a hospital. I've been thinking about going back to school for a nursing degree (associate's from a local community college), working for a year or so to get some clinical experience, and then getting into the infection control field and had a few questions.

In general, how much clinical experience would I need to qualify for IC jobs? Would one year be enough?

What areas of the hospital would give me the best clinical experience for IC jobs?

Would my lack of a BSN hurt me when lookign for jobs or would by previous epidemiology training and experienc make up for that?

Thanks for any answers or advice you might have for me.
