People need to calm down about MRSA. Do you realize how many people are colonized by MRSA and have no signs of being infected? Walk into any tertiary care hospital and see how many patient rooms have contact precaution signs on the doors. At my hospital, which is one of the top academic medical centers in the US, we screen every patient (for carrier status) admitted to the hospital using PCR of their nasal secretions. I have been working with MRSA carriers for years now and I have had no problem. I am sure that at this point I am colonized. There are quite a few antibiotics that are still effective against MRSA. You just need to worry about the bugs that are resistant to vanc/zosyn/daptomycin/linezolid/meropenem. The bugs that are resistant to all of those are so incredibly rare that you don't need to worry about them unless you are working in a large tertiary hospital where they use tons of those antibiotics, such as is common on Heme/Onc/BMT units.
