Good Afternoon-Can someone give me some general information on MRSA. My husband (age 32) was told it was detected about year ago . Up until then he was very active and only needed to have IV's once every year or so. Within the last year he has been in the hospital 4 times and each time he has been admitted MRSA has returned. Does MRSA cause infection? The Doctors are not being very clear, most say it doesn't cause infection. Any information would be appreciated.
