As long as you become APIC (American Professionals in Infection Control) certified, I think you'll find opportunities anyplace, though of course they aren't plentiful. Becoming APIC certified in the ticket and it does an excellent job making sure that you know your business.
In 2004 I was extremely frustrated. I had been told that becoming a MT (Medical Technologist) was the "way to go," to get into IC. I started out wanting to become the IC in a hospital. I was actually told wrong (I believe the RN route is bettter), but after finding the MT program too boring I switched and became an RN.
After working hospital Med/Surg and then moving to a large tertiary Adult ICU, I was even more frustrated. Back in 2004 to sit for the APIC exam you must have worked in Infection Control for a year (part-time was ok). I begged the IC department to let me work, even for free, just 4 or 8 hours a week--no go. (In retrospect it may have been a political decision, which translated to: "don't you dare take any of our ICU nurses away!"
I lost a great deal of respect for APIC then, especially after writing to many people within 100 miles of me who were APIC active (state chapter leaders) and not getting a single response. My take was this fictional discussion was how most people got into APIC:
"Oh, you're so sick of being a floor nurse, why not become our IC nurse?"
"But I have to have been working IC for at least a year to take the exam, and I haven't."
"Of course you have, you practice safe procedures, that's infection control, here I'll sign off for you..."
Seriously, here I was, one of the very few who started my education specifically to become an IC professional, and found myself totally locked out of it. Essentially this requirement locked out some of the people truly interested in the field, while letting others in simply because it, in some places, can be a fairly tranquil job. (Note: While that take may be common--it is NOT always tranquil).
Interestingly APIC has dropped the "practice requirement" meaning that you can take a job as IC for a hospital/rehab and immediately sit for the APIC cert exam. Dropping the work requirement from one year to one day is interesting.
At any rate I would suggest that you utilize your position and study the APIC curriculum, and sit for the exam. Once you are APIC certified, you're golden. Every job that I have ever seen requires APIC certification, there may be some at small facilities that do not require the cert, but they are few.
Good luck and give those 'lil buggers (nasty bacteria/viruses/parasites, etc) a hard time.
