Can a mandate stop hospital staph infections?

My lede:

The rate of patients entering the hospital with methicillin-resistant Staphylococcus aureus increased eightfold between 1999 and 2006. Politicians in statehouses around the country say hospitals need to take a more active approach to stopping MRSA’s spread.

Since 2007, four states — California, Illinois, New Jersey and Pennsylvania — have enacted laws requiring hospitals to screen high-risk patients for MRSA infection or colonization and follow precautions to prevent other patients from becoming infected. Eight states considered similar legislation last year, and as of late January, new bills had been filed in Washington and Kentucky.

The whole shebang.
