Methicillin resistent S. aureus (MRSA) is one of main causative bacterias of nosocomial infection Recently their prevcalent rate has continuously increase in Korea, so we have studied the incidence rate of MRSA strains which was isolated from
microbiology laboratiory in Sanggye Paik hospital between September 1st, 1993 and february 28th , 1994. And we compared the incidence rate of MRSA among various groups ; physicians, nurses, aides, and medical laboratory technicians. The incidence
rate
of MRSA among S. sureus was 57% (N=227). Among 87 hospital personnels screened, the nasal cavity and hand carrier rates of MRSA in hospital personnel groups which have had direct contact to patients were 78.6% and 50%, respectively, but the one
of
MRSA
in medical laboratory technician group which has not had direct contract to patients were 0% and 0T respectively, of all isolated. S. aureus.
We concluded that hospital personnels were primarily infected by MRSA from patients and spread of MRSA from patients to patients in hospital appeared to have occurred seocndarily by direct from hospital personnels who were nasal cavity or hand
carrier
of MRSA.
