Physicians: Community Associated MRSA
 

is the medical community much concerned?

Very much so. In the community where I practice, when a patient presents with a suspected staph infection (abscess), I will drain the abscess and treat empirically for MRSA with either vancomycin or clindamycin. Reason being that about 30% of these will be MRSA and you can't afford to loose 3 days of treatment waiting for your cultures to come back. About 98 % of the community acquired MRSA is sensitive to clindamycin which also comes in an oral form.

When the 2% turns into 50% how will it be treated? Anyhting in the pipeline?

MRSA is still > 99% sensitive to Vancomycin. If this fails the next is Linezolid (Zyvox).
