In particular, researchers in San Francisco have documented an "alarming" prevalence of community-acquired MRSA in hospitalized patients. Since 2000, there has been an "exploding prevalence" of MRSA, largely fuelled by the epidemic spread of a single clone (known as ST8:USA300) in the community."The early consequences of an escalating epidemic of community-acquired MRSA infections involved the spread of the epidemic clone into the hospital environment and the development of multidrug resistance," Diep said. The researchers found that result when they first screened laboratory reports from January 2000 to June 2004, and came up with more than 2,500 cases of MRSA. They then performed a detailed analysis of a random sample of 389 patient isolates. The sample was stratified according to hospital- or community-onset of infection, as defined by the time of each patient’s first MRSA culture.During that period, community-acquired MRSA accounted for more than 81% of unique infections, and 42% of the community patients required hospitalization.
