The role of healthcare workers in MRSA transmission

Is discussed in a paper in the Lancet Infectious Diseases - are healthcare workers the source of the infection, or a vector, or something else?

Conclusions (looking quickly) seem to be that they are important as a vector, but possibly not as a source.

I think I am a little worried by the search strategy, which doesn't seem to include alternative terms for "MRSA", just "MRSA" (does this matter, I wonder?), and doesn't seem to include specific healthcare workers, only the phrase "healthcare worker(s)". The authors did however use the Outbreak Database, http://www.outbreak-database.com/, which was new to me. Not sure if this is a current database - it seems to have started with information from a Medline search done up until 2002. The search page doesn't seem to be working at the moment.

Paper is:

Albrich WC, Harbarth S. Health-care workers: source, vector, or victim of MRSA? Lancet Infectious Diseases 2008; 8(5): 289-301.
